5.0.0 - 23 Oct 2015

PSPDFKit 5 is a major new version, introducing our own renderer and focusing on improving performance. It requires Xcode 7.1 and is compatible with iOS 8.0 - 9.1. This release is a huge usability improvement with Swift but also Objective-C, as we annotated all headers with generics. This release now shares our new core with our Android SDK to further improve quality and performance.

Changed

PSPDFKit now uses its own PDF renderer and no longer uses Apple's Core Graphics renderer, which means better performance, stability and quality. (#3737)
Changed

Undo and redo now remember individual lines drawn instead of the previous behavior where undo removed the whole annotation, once committed. (#2825)
Changed

The tabbed bar has been completely redesigned and now supports animations and reordering, not to mention it being much prettier. (#665)
Changed
View controllers are now presented using UIPresentationController and are much easier to handle and dismiss. (#3519)
- Changed
  
  We removed the popoverController and halfModalController properties, as these are now custom presentation styles.
Changed

Popovers are no longer dismissed on rotation. (#3519)
Changed
iOS 8 adaptivity is fully supported: view controllers swap between being popovers, half modal or full screen depending on context. (#3743)
- Changed
  
  A new presentation option has been added to prevent view controllers from adapting their presentation style: PSPDFPresentationNonAdaptiveKey.
Changed
The default presentation style has changed for presentViewController:options:animated:sender:completion: from PSPDFViewController and PSPDFPresentationActions. The default is now to use the presented view controller’s modalPresentationStyle, similar to the old PSPDFPresentationStyleForceModal style, which has been removed.
- Changed
  
  To restore the equivalent of PSPDFKit’s previous default behavior (using either a popover or full screen, depending on the space available), set the presented view controller’s modalPresentationStyle to UIModalPresentationPopover.
Changed

The annotation toolbar now automatically adapts its items depending on the available screen real estate. This change comes with a new API that allows setting multiple toolbar configurations amongst which the toolbar picks the optimal layout. (#3950)
Changed
The free text input accessory view has been updated to show popover pickers whenever possible, with a fallback to the half modal inspector, if vertical space is tight. (#3987)
- Changed
  
  Note: We noticed some input accessory view resizing issues on iPad Air 2 Simulator. We could not reproduce the same problems on actual devices.
Changed

We’re using UIAlertController and UISearchController everywhere, replacing the older deprecated API for further view controller unification. (#3381)
Changed

Automatic double page mode is smarter, comparing the aspect ratios of the view and the document and only showing two pages if they fit without too much shrinking. Automatic mode is now the default on iPhone too, but since two pages are only shown in large views the behavior will be similar.
Changed

By default, page thumbnails are now sized adaptively to comfortably fill the available space.
Changed
Instead of CGPDFDataProvider we now have a new PSPDFDataProvider protocol, which finally allows writing as well. (#3690)
- Changed
  
  PSPDFAESCryptoDataProvider has been updated to allow writing annotations back into the secure storage.
Changed

Safari view controller is used instead of PSPDFWebViewController on iOS 9.
Changed

PSPDFScrobbleBar has been renamed to PSPDFScrubberBar to better express its purpose.
Changed

Changed

PSPDFAnnotationStateManager now supports multiple delegates and the delegate protocol gained some new methods. (#3607)
Changed

The color menu is now represented visually, and uses the style manager color presets. (#2802, #2890)
Changed

Switching between regular and callout styles for text annotations now produces better results and has been made easier with a redesigned UI. (#3664 and #3859)
Changed

The annotation stream now gets properly reset when an annotation is modified, preventing stale content from being rendered on screen. (#3817)
Changed

PSPDFDocumentActionExecutor’s presentationController has been renamed to sourceViewController to better describe its purpose and avoid confusion with UIPresentationController.
Changed

The prefersStatusBarHidden property in the PSPDFStyleable protocol has been renamed to forcesStatusBarHidden to be distinct from the closely related UIViewController method of the same name.
Changed

It is now possible to show color presents on PSPDFAnnotationStyleViewController, even if color and opacity settings are disabled. Color presets can still be hidden by adjusting typesShowingColorPresets. (#4108)
Changed

Accessibility and voice over support has been improved on some of our key UI elements. (#3834)
Changed

The author username is now requested earlier and managed via the new PSPDFUsernameHelper class.
Changed

The border radius of PSPDFSearchHighlightView is now dynamically calculated based on the current zoom level and can be configured via cornerRadiusProportion.
Changed

PSPDFImageInfo is now much more reliable and detects more image formats.
Changed

PSPDFActions nextAction is now an array to correctly reflect the PDF spec, and the whole tree is iterated as required upon execution.
Changed

PSPDFRenditionAction now also exposes optional attached javascripts.
Changed

The hooks for markedContentStack and shouldParseCharacter: in the PSPDFTextParser have been removed since they were very rarely used but caused a noticeable slowdown for all text extraction. If there's demand, we'll look into ways to reintroduce a similar feature with less performance impact.
Changed

prefersStatusBarHidden in PSPDFStyleable has been renamed to forcesStatusBarHidden to not confuse this with properties that UIKit recently introduced.
Changed

Several annotation classes have new parent types to unify certain features, such as PSPDFAssetAnnotation and PSPDFAbstractShapeAnnotation.
Changed

Small UI updates across the board. (For example, dark colors are easier to see in menus.)
Changed

Various lesser-used API has been redesigned or removed for better clarity.

This release will be one of our last v4 releases, while v5 for iOS 9/8 is steadily nearing completion with a huge list of updates/improvements. We backported the new bezier path calculation code, so ink annotations are quite a bit faster now. There's a lot more coming soon!

Changed

When invoking search, we now prioritize the current visible pages before searching the rest. Search results will show up significantly faster on complex documents. (Z#1829)
Fixed

Fixes an issue where resetting choice form elements didn't always reset all properties. (Z#1813)
Fixed

Fixes an issue when applying a PSPDFRenderFiltersKey on rotated documents. (#3892)
Fixed

Fixes a rare floating point precision issue that could cause pages to show up distorted. (#3882)
Fixed

Fixes an issue where rotation caused ill–positioned pages when switching from single–page to two–page layout. (#3878)

4.4.13 - 28 Aug 2015

Changed

Improves rendering during annotation selection, decreasing the possibility of stale content. (#3488)
Changed

Improves behavior for the go to page dialog when invalid numbers are entered. (#3662)

4.4.11 - 31 Jul 2015

Added

Adds Czech, Greek and Finnish translations and updates various other localization details.
API

The rotationLock has been removed. Subclass PSPDFViewController and override the rotation methods and/or implement supportedInterfaceOrientationsForWindow: to lock rotation.

Changed

Text selection now supports text-to-speech on iOS 7+. See PSPDFSpeechSynthesizer for details and options to customize the language.
Changed

Forms on iPhone/iOS 7 now have an automatic zoom feature that makes it a lot easier to enter text.
Changed

Search now also includes annotation and form element contents. This is especially useful for note annotations and forms. (PSPDFKit Basic/Complete)
Changed

Search results are now hidden on page tap (unless that tap finds an action like selecting an annotation.)
Changed

Note annotations are now always rendered at the same size and also visible in the thumbnails.
Changed

PDF annotation writing will now be faster and produce a more compact trailer, reducing target file size.
Added

Adds support for mailto: links with multiple email addresses (also for CC and BCC).
Changed

Saving will now use the correct z-index for annotations and forms in the same ordering as they are added. Saving changed objects will no longer change the z-ordering.
Changed

Simple JavaScript actions like printing, alert boxes or adding form values now work. If you have a use case for that, please contact us at support@pspdfkit.com.
Changed

The XFDF parser now parses basic rich text strings as used in Acrobat and keeps color and font informations.
Changed

Increases contrast for the selection color on form choice list-boxes.

Changed

The behavior of the pdfViewController:didTapOnPage:View:atPoint: has been updated when no PSPDFPageView was hit to return nil here, and coordinates relative to the current PSPDFViewController.
Changed

The PSPDFThumbnailBar has a new parameter to optionally enable the page labels: showPageLabels (defaults to NO).
Changed

Many improvements related to PDF AcroForm handling and input validation.
Changed

Calls to didHidePageView: and didShowPageView: of views with the PSPDFAnnotationViewProtocol are now properly balanced.
Changed

The text parser now has a more sophisticated text shadow/overlay detection, which improves search results by removing duplicated glyphs.

Font annotations are now rendered with their AP stream for greater document accuracy.
Changed

Annotations now support the additional action mouse up event.
Changed

API

PSPDFProgressHUD has been replaced with the all-new PSPDFStatusHUD, which features a modern iOS 7 design and an improved API.
API

PSPDFDocument should be treated as an immutable object (apart from settings). Thus, the files and fileURL properties have been made readonly, and appendFile: has been removed. Create a new document with the new files/data objects instead. Use the new helper documentByAppendingObjects: to create a modified document with a new file or data objects.
API

The PSPDFAnnotationManager now supports various protocol strings, thus the property protocolString has been renamed to protocolStrings and is now an NSArray that takes NSStrings. We've added embed:// as a second, neutral protocol format.
API

The textSearch class has been moved from PSPDFDocument to PSPDFViewController.
API

PSPDFNoteAnnotationViewFixedSize has been removed. Notes are now drawn with a fixed size, however you can define the bounding box to whatever you like. We recommend using 32px, but this value is being ignored by both PSPDFKit and Adobe Acrobat. Other, less capable renderers like Apple Preview.app might use the value, so 32px is a good value - but also depends how large or small your document is.
API

The PSPDFSignatureViewController no longer dismisses itself. Dismiss the controller in the delegate callbacks.
API

Code and subclassing hooks that could be used to change the PSPDFScrobbleBar frame have been moved to PSPDFHUDView.

3.3.0 - 29 Dec 2013

Happy holidays!

PSPDFKit now requires iOS 6+ and Xcode 5. Keep using PSPDFKit 3.2.x if you're still building with Xcode 4.6 or need to support iOS 5. Apple will enforce usage of Xcode 5 starting February 1st. (https://developer.apple.com/news/index.php?id=12172013a) Removing iOS 5 resulted in deleting almost 10.000 lines of code - which will give you a smaller, faster and more efficient binary.

The binary is now again fully universal including armv7, armv7s, arm64, i386 and x86_64. The separate iOS 7 only (64 bit) library variant has been removed.

PSPDFKit Complete now supports PDF form signature validation and thus links with OpenSSL. There is an optional build without OpenSSL that disables these cryptographic signature checks.

Changed

Localization! PSPDFKit now ships with English, Chinese, Korean, Japanese, French, Spanish, Russian, Italian, Danish, German, Portuguese and Brazilian Portuguese.
Added

Adds preliminary compatibility with Xcode 5.1 and iOS 7.1b2.

Changed

PSPDFKit Complete/Enterprise can now validate cryptographic signatures (unless you use the build without OpenSSL)
Changed

PSPDFAESCryptoDataProvider now supports the popular RNCryptor data format: https://github.com/rnapier/RNCryptor/wiki/Data-Format (It autodetects the legacy format and supports that as well)

Finally fully supports the new UIViewControllerBasedStatusBarAppearance. (we now support both modes in iOS 7)
Changed

The PSPDFAnnotationToolbar now displays the style picker for text markup annotations (highlights).
Changed

The PSPDFGalleryViewController now supports local/remote video and audio files next to images.
Changed

The internal PSPDFWebViewController now shows a progress bar, much like Safari on iOS 7.
Changed

Improves automatic font resizing for single line text field form entries.
Changed

Improved support for additionalActions and nextAction to add actions to all annotation types.
Changed

API Change: PSPDFTextSelectionMenuActionWikipediaAsFallback has been renamed to PSPDFTextSelectionMenuActionWikipedia. Since checking for a word in UIReferenceLibraryViewController can be unpredictably slow as of iOS 7.0.3, we had to remove this feature. Define will now always be displayed and you can optionally enable Wikipedia as well. The new default will omit Wikipedia by default.
Changed

Don't show the PSPDFWebViewController bottom toolbar on iPhone if there are no availableActions defined.
Changed

Allow detection for a PSPDFKit signature and blocks the "Copy" feature if detected. Will also be saved into the PDF as proprietary extension.

Changed

Brand-new image gallery (define a region in the pdf to be covered by a smooth gallery). Allows configuration via inline-pdf or external JSON.
Changed

Use menu-based annotation manipulation for text markup annotations.
Changed

The way how the document UID is generated has been changed. Previously, for files it used the full app path. However since the app UID could change after an upgrade, we had to change this behavior. This is only important if you used bookmarks or allowed annotations saving into the internal storage - not for embedded annotation data. Set the global variable PSPDFUseLegacyUIDGenerationMethod to YES to continue using the old path. Those files are in Library/PrivateDocuments. You might want to write a custom migration step to rename the custom data paths from the old UID to the new UID system. The PSPDFUseLegacyUIDGenerationMethod can be changed at any time to switch between old and new UID (generate a new PSPDFDocument instance to force UID regeneration).
Changed

The file-based annotation backing store by default no longer saves link annotations but instead merges the saved annotations and the links from the file. This improves performance for PDFs that have lots of internal links (our current way of saving starts to get slow once there are more than 10.000 objects). In most cases, you don't need to care and your save file will be migrated automatically. If you rely on custom link annotations being saved/deleted, you need to set the new saveableTypes property of the fileAnnotationProvider back to the old default PSPDFAnnotationTypeAll.

Important! Currently PSPDFKit 3 requires that you set the key UIViewControllerBasedStatusBarAppearance to false in your project Info.plist file. We're working on supporting view controller based status bar appearance in a future update.

Note: Several methods and constants have been updated and renamed to make the API cleaner. Read the PSPDFKit 3.0 Migration Guide if you're updating from version 2.

Important: PSPDFKit 3 requires a serial number and will run in demo-mode by default. Visit https://customers.pspdfkit.com to register your app bundle ID and get the serial. If you are a PSPDFKit 2 customer with a license that includes a free PSPDFKit 3 update, please contact support@pspdfkit.com with your PET* purchase number to get an invite.

PSPDFKit 3 still supports iOS5, however we plan to drop support for it later this year. We already see less than 5% usage and expect this number to drop further in the future.

With the release of PSPDFKit 3 we will focus development on this version and won't be able to offer support for version 2 anymore. Most customers who bought PSPDFKit after January 14th are eligible for a free update, if your update window is still open (6 months for Binary/Viewer, 12 months for Source/Enterprise) Contact us with your PET* purchase number (or invoice ID) for details on your status.

Changed

Paste also supports general pasteboard types like Text, URL or Image and will create the appropriate annotations (if this is allowed)
Changed

New global PSPDFStyleManager that saves various annotation properties and applies them to new annotations. For example, if you change the color of a highlight to red, all future annotations are created red until you change the color back.

You can disable this with nilling out the styleKeys property of PSPDFStyleManager.
Changed

The PSPDFFreeTextAnnotationView is now always sharp, even when zoomed in. Because we have to work around the broken contentsScale property, the API has changed a bit. If you previously had textView overridden, you now need to subclass PSPDFFreeTextAnnotationView and change the textViewForEditing method to apply your custom textView.
Changed

PSPDFStampViewController is now more flexible and will evaluate the new PSPDFStampAnnotationSuggestedSizeKey key for the default annotations.

If a new PSPDFViewController is created based on a PDF action that links to a new document modally, all important settings are copied over to the new controller.
Changed

PSPDFKit will no longer create empty highlight annotations when using the annotation toolbar and tapping on a point without text.
Changed

No longer retains the view controller while the document background cache is being build (less memory pressure)
Added

Adds some more safeguards against abuse of certain methods.
Changed

The render queue now retains the document while rendering. This fixes cases where image requests never returned because the document disappeared before.
Fixed

Fixes a regression from 2.10 where through an event optimization sometimes the text of a note annotation was not properly saved. PSPDFDocument now sends out a PSPDFDocumentWillSaveNotification before a save will be made to give all open editors a chance to persist it's last state in time.
Fixed

Fixes an issue where the contentRect was calculated wrong for uncommon view embedding use cases.
Fixed

Fixes an issue where the thumbnail filter values were hardcoded.
Fixed

Fixes a potential timing-related crash on iOS5 when the search controller was shown too fast.
Changed

Titanium: Add thumbnailFilterOptions property.

2.10.1 - 26 Mar 2013

Changed

Shape annotations border and fill color can now be customized.
Changed

Clearing the memory cache will now also clear any open document references.
Added

Add white color to common color picker colors (except for highlights, replacing purple)
Changed

PSPDFRenderQueue now has a cancelAllJobs to clear any running requests.
Changed

The render queue now better prioritizes between cache requests and user requests (zooms) to allow even faster rendering.
Changed

FreeText annotations can now no longer be created outside boundaries.
Added

Add support for text alignment for FreeText annotations. (It seems that Adobe Acrobat has a bug here and ignores this property - other Applications are compliant to the PDF spec and do display this, e.g. Apple's Preview.app)
Changed

Edit mode now directly hides the HUDView.
Changed

API change: The color picker now has a context: flag to allow state storage. Update your delegates if you use this class directly.
Fixed

Fixes some minor issues with the new cache.
Fixed

Fixes a UI weirdness where the scrollview had a slow scroll-back animation when text was edited at the very top.
Changed

Titanium: Add new linkAnnotationHighlightColor property.

2.10.0 - 22 Mar 2013

PSPDFKit 2.10 is another major milestone. The cache has been rewritten from the ground up to be both faster and more reliable. Annotations are now cached, they are no longer an "afterthought" and will show up in the thumbnails and even the scrobble bar. The disk cache now limits itself to 500MB (this is customizable) and cleans up the least recently used files. The memory cache is now also smarter and better limits itself to a fixed number of pixels (~50MB of modern devices in the default setting). Loading images from the cache is now more logical and highly customizable with PSPDFCacheOptions. The two render code paths have been unified, PSPDFRenderQueue now does all rendering and can now render multiple requests at the same time and also prioritizes between low priority cache requests and high priority user zoom requests. In this process some very old code has been completely reworked (PSPDFGlobalLock) and is now much more solid. Several methods have been renamed, upgrading will require a little bit of effort to adapt to the new method names. It's definitely worth it. If you find any regressions or missing features for your particular use case, contact me at peter@pspdfkit.com.

Changed

Completely rewritten cache that now renders all screen sizes and shows annotations.
Changed

PSPDFThumbnailViewController now has a new filter to only show annotated/bookmarked pages. See filterOptions for details. http://twitter.com/PSPDFKit/status/314333301664006144/photo/1

Prevent too fast tableView updates (and thus flickering) in PSPDFSearchViewController.
Changed

Increases loupe magnification on iPhone to 1.6 and make kPSPDFLoupeDefaultMagnification customizable at runtime.
Changed

A UISplitViewController in the hierarchy is automatically detected and the pan gesture will be blocked while the PSPDFViewController is in drawing mode (else this would interfere with drawing).
Changed

The note annotation controller now no longer generates change events per typed key, but will wait for a viewWillDisappear/app background event to sync the changed text back into the annotation object.
Changed

Expose availableLineWidths and availableFontSizes in PSPDFPageView to customize menu options.
Changed

On iPhone, scrolling down the search results will now automatically hide the keyboard.

Add workaround against rdar://13446855 (UIMenuController doesn't properly reset state for multi-page menu)
Changed

The selectionBackgroundColor of PSPDFSearchHighlightView can be updated after it's displayed now.
Changed

PSPDFTabBarView of PSPDFTabbedViewController can now be overridden with the overrideClassNames dictionary.
Changed

API change: The renderBackgroundColor, renderInvertEnabled, renderContentOpacity methods have been removed from PSPDFViewController. Please instead update the dictionary in PSPDFDocument to set these effects. (e.g. document.renderOptions = @{kPSPDFInvertRendering : @YES}).
Changed

API change: PSPDFViewController's renderAnnotationTypes has been deprecated and will update the renderOptions in PSPDFDocument instead.
Changed

API change: renderPage: and renderImageForPage: will now automatically fetch annotations if the annotations array is nil. To render a page without annotations, supply an empty array as the annotations array (as soon as an array is set, auto-fetching will be disabled).

The loupe has been improved, it's now fast in every zoom level and now 100% matches UIKit's look. Developers can now easily update the magnification level.
Changed

Greatly improved UIAccessibility support. Reading mode is now line-based and reading column-based layouts works much better.
Added

New feature: PSPDFScrobbleBar can control tap behavior outside the page area with allowTapsOutsidePageArea.
Changed

Improved PDF rendering speed for pageCurl mode.
Changed

RichMediaAnnotations (directly embedded video) now support autoplay set directly via Adobe Acrobat (Both page visibility modes will enable autoplay)
Removed

Removes deprecated methods from PSPDFViewController and PSPDFPageView.
Changed

NSNull entries are now properly filtered out from the PDF metadata.
Changed

Greatly improves outline parsing speed. In some cases parsing of extremely complex outlines went down from 120 seconds to 2 seconds (in a ~5000 pages document)
Added

Add progress while data is transferring when using the "Open In…" feature.
Changed

Changed

UIMenuController is now smarter and no longer places the menu above the toolbar when there's space underneath as well.
Changed

'allowTwoFingerScrollPanDuringLock' in PSPDFAnnotationToolbar now defaults to NO, since this delays drawing.
Changed

API change: Refactored the thumbnail view out of PSPDFViewController into it's own controller: PSPDFThumbnailViewController. If your code relied on modifying the collection view delegates within PSPDFViewController, you must update your code to override PSPDFThumbnailViewController instead. PSPDFViewController' gridView has been deprecated. Use thumbnailController.collectionView instead.
Changed

API change: Removed iPhoneThumbnailSizeReductionFactor. item size is now set conditionally during initialization. The best way to set this is in PSPDFCache.sharedCache.thumbnailSize.
Changed

Fixed

Fixes an off-by-one error in PSPDFOutlineParser's resolveDestinationNameForOutlineElement.

2.8.6 - 20 Feb 2013

Changed

PSPDFShapeAnnotation now creates appearance stream data. This is needed to work around a bug in Adobe Acrobat for iOS. This behavior can be disabled with setting kPSPDFGenerateAPForShape to @NO in renderingOptions of PSPDFDocument. As a side effect, this also improves display of transparent shapes with Apple's Preview.app
Changed

Improvements to smart zoom - text block choose method is now smarter.
Changed

viewLock no longer locks the HUD (just the view state)
Changed

Improves animation for the Table of Contents controller cells.
Changed

Removed

Removed deprecated options from PSPDFEmailBarButtonItem.

2.8.2 - 10 Feb 2013

Changed

HUD visibility/transparency can now be set more fine-grained with the new properties transparentHUD, shouldHideNavigationBarWithHUD, shouldHideStatusBarWithHUD and statusBarStyle.

Fixed

Fixes a touch inconsistency where a annotation deselection could be done without marking the touch as processed.
Fixed

Fixes several entries in the localization table.
Fixed

Fixes a regression introduced in 2.8.1, a potential crash when using the highlight annotation tool outside of a glyph.
Fixed

Fixes a potential crash in the search view controller due to invalid state handling.
Fixed

Fixes an issue where part of the drawing state was lost when opening a modal controller while in drawing mode. (e.g. iPhone/color picker)
Changed

Various typos fixed, and some very minor API changes due to spelling corrections (thanks to Tony Tomc).

2.8.1 - 6 Feb 2013

Changed

The highlight tool now matches full words. A single touch will highlight the complete word instead of just one character.
Changed

A new syntax for link annotations to control UI. For now pspdfkit://control:outline is supported to open the TOC directly from the document.
Changed

The signature controller now uses "Signatures" as title instead of "Choose Signature" on iPhone, since later was too long and got cut off.
Fixed

Fixes an issue where setFileURL: could generate a new UID if one was already set.
Fixed

Fixes an UI issue when resizing an annotation purely horizontally would result in no redraw.
Fixed

Fixes an UI issue where the thumbnail indicator could move behind the thumbnail image in some cases.
Fixed

Fixes an UI issue in PSPDFFixNavigationBarForNavigationControllerAnimated() that could potentially shift down the navigationBar for unusual view controller setups.
Fixed

Fixes an UX issue where a second tap was sometimes required after using certain modes in the annotation toolbar.
Fixed

Fixes an issue where an external PSPDFBarButtonItem would not update on iPhone.
Fixed

Fixes an issue where videos played in a popover continued to play even after the popover was dismissed.

2.8.0 - 5 Feb 2013

Changed

Image annotations. PSPDFKit can now add images from the camera and the photo library and embed them as stamp annotations.
Changed

Search / Text extraction is now more than twice as fast and reports the current page.
Changed

The whole AP stream generation system has been improved and performance optimized to allow bigger streams like images.
Changed

PSPDFKit will now require Xcode 4.6/SDK 6.1 to compile. (4.5 should still work fine, but we follow Apple's best practice with always compiling with the latest SDK available.)
Changed

API change: editableAnnotationTypes is now an ordered set. Using a regular set to change this property will work for the time being, but please update your code. The order now will change the ordering of the buttons in the annotation toolbar and the new annotation menu.
Added

Add experimental phone/link detection: detectLinkTypes:forPagesInRange: in PSPDFDocument. This will create annotations for phone numbers and links found in the document, if they are not linked already. This is the same that Preview/Mac and Adobe Acrobat do - they allow to click URLs even if they don't have any link set on them.
Changed

Search now displays the current processed page.
Changed

Further tweaks to PSPDFHighlightAnnotation highlightedString.
Added

Add setting to enable/disable the "Customer Signature" feature. (customerSignatureFeatureEnabled in PSPDFSignatureStore)
Changed

The signature controller has now landscape as preferred rotation under iOS6. (but still supports portrait)
Changed

Controllers presented via the PSPDFViewController helper now use a custom PSPDFNavigationController that queries the iOS6 rotation methods of the topmost view controller. This makes it easier to customize rotation for PSPDF* controllers without hacks.
Changed

Performance improvement: deleted annotations now are no longer serialized if the external annotation format is used.
Changed

The "hide small links" feature now works better on iPhone.
Changed

FreeText annotations now parse even more font definition styles.
Changed

Improvements to the heuristic in PSPDFHighlightAnnotation highlightedString.
Changed

Changed

Smart zoom now uses less border when zooming into a text block, which looks better. (other columns usually are no longer visible)
Changed

Taps that dismiss an annotation editing popover no longer modify the HUD state.
Changed

The scrobble bar thumbnail size has been tweaked to be a little bigger. This now can also be fine-tuned, see PSPDFScrobbleBar.h.
Changed

The font selector now selects the currently chosen font.
Changed

Various performance improvements. (esp. search and the color picker)
Changed

Thumbnails are now sharper and always aligned to pixel grid (fixes a bug in UICollectionViewFlowLayout)
Changed

Text selection knobs are now pixel aligned as well.
Changed

When thumbnails are loaded from scratch, they are loaded in order. (PSPDFCache's numberOfConcurrentCacheOperations has been set to 1)
Fixed

Fixes an UX issue where PSPDFKit could end up displaying something like '1 (1 of 2)' for page labels.
Fixed

Fixes an UX issue where a tap wasn't set to being processed when the delegate delegateDidTapOnAnnotation:annotationPoint:... was being used.
Fixed

Fixes an UIKit bug that in some cases froze the UIScrollView when we zoomed out programmatically (e.g. a double tap after already zoomed in)
Fixed

Fixes a potential crash when saving NSData-based PDFs with a corrupt XRef table.
Fixed

Fixes a rendering issue where some landscape documents were incorrectly scaled when using renderImageForPage:withSize in PSPDFDocument.
Fixed

Fixed

Fixes a regression in the 2.7.x branch that caused movies loaded in the PSPDFWebViewController to fail with the error "Plugin handled load".
Fixed

Fixes an issue when using Storyboard and setting the viewState to thumbnails initially.
Fixed

Fixes an issue where the signature selector controller dismissed the whole pdfController under certain conditions.
Fixed

Fixes an issue with annotations moving to other pages on a document with multiple document providers.

Fixed

Fixes an issue with zooming when in text edit mode and page centering.
Fixed

Fixes an issue with searching for certain characters that are reserved regex characters (like *+).
Fixed

Fixes an encoding issue with annotation content and certain Chinese characters.

2.7.5 - 25 Jan 2013

Changed

Signatures are now securely saved in the Keychain and a list of signatures is presented. To disable this feature, set PSPDFSignatureStore.sharedSignatureStore.signatureSavingEnabled = NO in your appDelegate.
Changed

While annotation mode is active (highlight, drawing, etc) scrolling is now enabled with using two fingers. The old behavior can be restored with setting allowTwoFingerScrollPanDuringLock in PSPDFAnnotationToolbar to NO.
Changed

PSPDFKit now requires Security.framework.
Fixed

Fixes an issue that could cause an initial "white page" when the controller is first loaded, even when there's cache data available.
Fixed

Fixes an UX issue where, with creating a new note, the menu could be displayed on iPhone, stealing the keyboard from the newly created note controller.
Fixed

Fixes a regression of 2.7.4 that broke some remote videos/audios.
Fixed

Fixes a potential issue when reordering bookmarks.
Fixed

Fixes an issue where the last letter was cut off when using PSPDFHighlightAnnotation highlightedString.

Added

Add more audio file formats to the support list. (aiff, cif, ...)
Changed

Ensure that addAnnotation:animated: in PSPDFPageView sets the page and documentProvider.
Changed

Better workaround for MPMoviePlayer's problem with multiple audio/video views on the same window. (A play button is now displayed in those cases)

Changed

Several tweaks for PSPDFProcessor PDF from web/office files generation.
Fixed

Fixes a potential crash in the iPhone popover controller.

Fixed

Fixes several issues with certain RichMedia embedded video annotations.

2.7.0 - 16 Jan 2013

Changed

PSPDFKit model classes now have a common base model class 'PSPDFModel' - allows to serialize/deserialize via JSON easily using externalRepresentationInFormat:. To get the JSON dictionary, use annotation externalRepresentationInFormat:PSPDFModelJSONFormat. (The old annotation serialization format is still supported for the time being)
Changed

PSPDFKit now requires AssetsLibrary.framework - if you're using PSPDFKit.xcproj or the source distribution, this is already been taken cared of. If you added the frameworks manually and get a linker error, make sure you are linking sAssetsLibrary.framework.
Changed

PSPDFMenuItem learned to show images in UIMenuController - this beautifies many of the annotation menus, images are now used for annotation types/colors where appropriate.
Changed

PSPDFKit has learned to write appearance streams. Currently they are emitted for Stamp and Ink annotations. This will help to further improve annotation compatibility with some apps that behave less standard compliant (like Adobe Acrobat/iOS, last tested version is 10.4.4, which doesn't show Ink annotations if they do not have an attached AP stream, even if this is invalid behavior according to the PDF spec. (GoodReader/Preview.app/Adobe Reader on the Mac don't require an AP stream and work in compliance to the spec.))
Changed

Annotation menus have been cleaned up a little, Opacity... has been moved into a submenu of Color for highlight annotations.
Changed

PSPDFProcessor has learned to write annotations as dictionary, not only flatten. This will be used e.g. for Open In... when the original PDF is not writeable and thus annotations are saved in an external file.
Changed

Open In... will now create a new file if there are annotations and the source PDF is not writeable itself.
Changed

Stamp annotations now have limited support for appearance streams.
Changed

Stamp annotations can now be added via the new PSPDFStampViewController.
Added

Add experimental pageRange feature in PSPDFDocument to allow showing of a subset of the pages.
Changed

Highlight annotation hit testing is now more accurate, checking the specific rects of the highlights, not the outer boundingBox.
Changed

Annotation rendering now checks if the annotation will be visible at all and only then renders the annotation. This speeds up zooming on complex documents with many annotations.
Changed

Improves search by ignoring certain whitespace characters like no-break-spaces.
Changed

Allows to create password protected PDFs with PSPDFProcessor up to AES-128 (and mix other CGPDFContext properties like kCGPDFContextAllowsPrinting or kCGPDFContextAllowsCopying)
Changed

Improves word detection with splitting words between a line of thought and adding special logic for non-default whitespace characters. to use the old behavior.
Changed

Improves french translation.
Changed

zIndex of annotation images is now below zIndex of links, so that links are always displayed before annotation images.
Changed

Email sending using PSPDFEmailSendMergedFilesIfNeeded will not perform a merge if there is only one source document.
Changed

Links are now handled even if they are overlapped or hidden underneath other views.
Changed

Hides the page label and the scrobble bar if the document is password protected and not yet unlocked.
Changed

PSPDFAnnotation now shows if an appearanceStream is attached.
Changed

PSPDFAnnotation now as a userInfo dictionary to add any custom data.
Changed

Annotations now have a creationDate.
Changed

When note annotations are tapped, don't fade-animate the former annotation out.
Changed

Page label will not be displayed if the page label is simply the real page number. (Prevent titles like 2 (2 of 10))
Changed

The internal web browser will now display an error within the HTML, much like Safari on iOS: https://twitter.com/steipete/status/287272056524001280
Changed

Selected images now have a (default iOS light blue) selection state, matching the selection behavior of glyphs.
Changed

Brightness control now has indicator images for less/more brightness and a better icon.
Changed

Improves performance for pages with many links by dynamically disabling the rounded corners in that case.
Changed

External PDF links can now be opened modally in a new controller, use [modal:YES] in the option field, e.g. pspdfkit://[modal:YES]localhost/two.pdf#page=4.
Changed

KNOWN ISSUE: Annotations can't yet be moved between pages. This feature is on our roadmap.

2.4.0 - 2 Nov 2012

PSPDFKit now requires iOS 5.0+ and Xcode 4.5+ (iOS SDK 6.0) to compile. (Support for iOS 4.3/Xcode 4.4 has been removed, support for iOS 6.1 and Xcode 4.6b1 has been added.)

2.4 is a big release and a great new milestone of PSPDFKit. If you upgrade, make sure to read through the full header diffs to make sure methods you were calling/overriding still exist and are not moved. Common methods like pageScrolling will always get a compatibility method for the time being. Methods/Properties are are deeper within the framework won't get a compatibility method, but it's usually pretty easy to figure out what the property was named before. I am planning on working on PSPDFKit for a long time, and as the API evolves, it's sometimes necessary to clean up and rename things so that the API stays clean and logical.

Changed

Huge refactoring of PSPDFAnnotationParser. It's now much easier to add custom annotation providers (see PSPDFAnnotationProvider). If you have subclassed saving/loading or other parts of PSPDFAnnotationParser, you most likely need to change this over to the new PSPDFFileAnnotationProvider.
Changed

Page scrolling is now even smoother. And finally removes the slight stuttering when pushing the PSPDFViewController - now animates like butter.
Changed

PSPDFShapeAnnotation can now be saved into the PDF.
Changed

Ink drawings can now customize the Thickness. Select an annotation and use the new "Thickness..." menu item.
Changed

Ink drawings and shape annotations can now also contain comment text.

Added

Add support for embedded and external RichMedia and Screen (Video) annotations of any size.
Changed

PSPDFBarButtonItem now has longPress-support. Long-Press on the bookmarkBarButtonItem to see the new PSPDFBookmarkViewController. Bookmarks can now also be renamed/reordered.
Changed

If there's no searchButton visible, the search invoked from the text selection menu now will originate from the selection rect.
Changed

The Open In... action now also works on multi-file documents and/or data/cgdocumentprovider based documents (will merge the document on-the-fly, shows a progress window if it'll take some time)
Changed

PSPDFBarButtonItem now also accepts a generic UIView as sender on presentAnimated:sender:. (makes it easier to manually call menu items from custom code)
Changed

Better support when barButtonItems are added to custom UIToolbars.
Changed

The internal used BarButtonItem subclasses are now exposed, so that they can be overridden and their icon changed.
Added

New activityBarButtonItem to share pages to Facebook/Twitter on iOS6.
Changed

Double-Tapping on a video now enables full-screen (instead of zooming the page. This does not apply to YouTube movies)
Changed

Greatly improves handling of multiple video views on one page/screen.
Changed

Annotation views now have a optional xIndex. Video has a high index by default, so link annotations won't overlap a video anymore.
Changed

No longer allowing text selection above video annotations.
Changed

PSPDFDocument now has a new property 'PDFBox' to customize the used PDF box (ClipRect/MediaRect/etc).
Changed

PSPDFPositionView has been renamed to PSPDFPageLabelView. PSPDFPageLabelView and PSPDFDocumentLabelView are now easier skinable with the common superclass PSPDFLabelView.
Changed

PSPDFLabelView has now a second predefined style (PSPDFLabelStyleBordered)
Changed

PSPDFPageLabelView can now show a toolbar item. Check out the "Settings for a magazine" example how to enable this.

Changed

Improves annotation parsing speed.
Changed

Shape/Circle annotations now correctly display their fillColor.

Changed

Exposes firstLineRect, lastLineRect and selectionRect on PSPDFTextSelectionView.
Changed

The text loupe now fades our correctly when in drag-handle-mode.
Changed

Improved caching of external resources like annotations/text glyphs on page init. Caching now won't overflow the dispatch queues anymore if A LOT of pages are loaded at the same time.
Changed

PSPDFWord now has a lineBreaker property to detect line changes.
Changed

PSPDFPageInfo now regenerates the pageRotationTransform when the pageRotation is changed manually.
Changed

PSPDFKit now checks if a URL can be handled by the system and weird/nonrecognizable URLS no longer open the "Leave Application" alert.
Changed

The PSPDFAnnotationBarButtonItem is now smart enough to choose the right animation depending if the toolbar is at the top/bottom (slide in/out from top/bottom)
Changed

Setting the UIPopoverController no longer removes preexisting passthroughViews.
Changed

The renderQueue now no longer renders the requested image if the delegate has been released in the mean time. (The delegate is now weak instead of strong)
Changed

UI: Undo/Redo buttons on the drawing toolbar are better placed on iPhone.
Changed

UI: The color selection button is now smaller on iPhone/Landscape.
API

PSPDFPageInfo is not calculated in PSPDFDocumentProvider. If you've overridden methods that affect PSPDFPageInfo in PSPDFDocument, you should move that code to a PSPDFDocumentProvider subclass.
API

"realPage" has been renamed to "page" and is now set-able. The old "page" has been renamed to "screenPage". This finally cleans up the confusion that has been around page and realPage. In 99% of all cases, you're just interested in page and can ignore screenPage. Please update your bindings accordingly. If you formerly did KVO on realPage, change this to page too. (There's a deprecated compatibility property for realPage, but not for the KVO event)
API

additionalRightBarButtonItems has been renamed to additionalBarButtonItems.
API

pageScrolling has been renamed to scrollDirection. A deprecated compatibility call has been added.
API

handleTouchUpForAnnotationIgnoredByDelegate has been moved to PSPDFAnnotationController.
API

pdfViewController has been renamed to pdfController on PSPDFTabbedViewController.
API

Warning! If you've used pspdf_dispatch_sync_reentrant in your own code, you now absolutely must create your dispatch queues with pspdf_dispatch_queue_create. Apple has deprecated dispatch_get_current_queue(), so we're now using a different solution. This will most likely affect you if you're using the "Kiosk" sample code of PSPDFCatalog.
Changed

2.3.3 - 18 Oct 2012

Note: This will be the last release that supports iOS 4.3*. The next version will be iOS 5+ only and will require Xcode 4.5+ (iOS SDK 6.0) If you're having any comments on this, I would love to hear from you: pspdfkit@petersteinberger.com The binary variant is already links with SDK 6.0 and will not link with 5.1 anymore. (It still works down to iOS 4.3 though)

(*) There is no device that supports iOS 4.3 and can't be upgraded to iOS5, and PSPDFKit already dropped iOS4.2 and with it armv6 in 2.0.

2.1.0 - 17 Sep 2012

Changed

New: PSPDFAESCryptoDataProvider. Allows fast, secure on-the-fly decryption of AES256-secured PDF documents. (PSPDFKit Annotate feature) Unlike NSData-based solutions, the PDF never is fully decrypted, and this even works with very large (> 100MB) documents. Uses 50.000 PBKDF iterations and a custom IV vector for maximum security. Includes the AESCryptor helper Mac app to properly encrypt your PDF documents.
Changed

Allow to customize caching strategy per document with the new cacheStrategy property. This is automatically set to PSPDFCacheNothing when using PSPDFAESCryptoDataProvider.

Changed

PSPDFOpenInBarButtonItem no longer performs a check for compatible apps. Checking this is pretty slow. An info alert will be displayed to the user if no compatible apps are installed (which is highly unlikely for PDF). You can restore the original behavior with setting kPSPDFCheckIfCompatibleAppsAreInstalled to YES.
Changed

The viewState is now preserved when another controller is displayed/dismissed modally. This mostly happened with showing/hiding the inline browser or the note text controller on an iPhone. After that the zoom rate was reset; this is now properly preserved.
Changed

The annotation toolbar now flashes if the user tries to hide the HUD while the bar is still active (and blocking that)
Changed

Various performance optimizations; especially scrolling and initial controller creation.
Removed

Removes sporadic vertical transition of the navigationController's navigationBar when HUD faded out.
Fixed

Fixes "Persistent Text Loupe" when moving over a link annotation while selecting.

Add additional checks so that even incorrectly converted NSURL-paths (where description instead of path has been called) work.
Fixed

Fixes a issue where annotations were not saved with multiple-file documents on all but the first file.

Changed

Improved memory usage, especially on iPad1.

2.0.0 - 8 Sep 2012

PSPDFKit 2 is a major updates with lots of changes and a streamlined API. There are some API deprecations and some breaking changes; but those are fairly straightforward and well documented.

You need at least Xcode 4.4.1 to compile. (Xcode 4.4/4.5 both run fine on Lion, Mountain Lion is not needed but recommended) PSPDFKit 2 is compatible with iOS 4.3 upwards. (armv7, i386 - thus dropping iOS 4.2/armv6 from version 1)

The installation has been simplified. You now just drop the "PSPDFKit.embeddedframework" container into your project. Next, enable the PSPDFKit.xcconfig project configuration. Here's a screenshot: http://cl.ly/image/1e1I2Z2e1D3F (Select your project (top left), select project again in the PROJECT/TARGETS tree, select Info, then change in "Based on Configuration file" from None to PSPDFKit.)

If you have the sources and embed PSPDFKit as a subproject, don't forget to also add PSPDFKit.bundle.

MAJOR NEW FEATURES: * Text selection! (PSPDFKit Annotate) (Includes Copy, Dictionary, Wikipedia support) * Annotations! (PSPDFKit Annotate) Highlight, Underscore, Strikeout, Note, Draw etc. Annotations also will be written back into the PDF. There is a new annotationBarButtonItem that shows the new annotation toolbar. * Smart Zoom (Text blocks are detected and zoomed onto on a double-tap; much like Safari) The PDF is now also dynamically re-rendered at every zoom level for maximal sharpness and quality. * Customizable render modes (enable/disable use of upscaled thumbnails). PSPDFPageRenderingModeFullPageBlocking is great for magazines. * Greatly improved Search. Faster, parses more font styles, compatible with international characters (chinese, turkish, arabic, ...) * Site Bookmarks (see bookmarksBarButtonItem and PSPDFBookmarkParser) * Support for VoiceOver accessibility (yes, even within the PDF!)

Further, PSPDFKit has been improved in virtually every area and a lot of details have been tweaked.

Changed

Inline password view. (Before, just a empty screen was shown when document wasn't unlocked.)

1.10.0 - 25 May 2012

This will probably be the last major release in the 1.x branch. Work on 2.x is already underway, with a focus on text selection and annotations.

This release has some API-breaking changes:

Added

New toolbar handling (breaking API change) The properties searchEnabled, outlineEnabled, printEnabled, openInEnabled, viewModeControlVisible have been replaced by a much more flexible system based on the PSPDFBarButtonItem class.

For example, to add those features under the "action" icon as a menu, use this: self.additionalRightBarButtonItems = [NSArray arrayWithObjects:self.printButtonItem, self.openInButtonItem, self.emailButtonItem, nil]; If you're looking to e.g. remove the search feature, set a new rightBarButtonItems array that excludes the searchButtonItem.

Likewise, the functions additionalLeftToolbarButtons, magazineButton and toolbarBackButton have been unified to self.leftBarButtonItems. If you want to replace the default closeButton with your own, just create your own UIBarButtonItem and set it to self.leftBarButtonItems = [NSArray arrayWithObject:customCloseBarButtonItem];

Changed

Resolving pdf link paths has changed. (breaking API change) Previously, if no marker like "Documents" or "Bundle" was found, we resolved to the bundle. This version changes resolving the link to the actual position of the pdf file. If you need the old behavior, you can set PSPDFResolvePathNamesEnableLegacyBehavior to YES or use a custom subclass of the PSPDFAnnotationParser.
Changed

New class PSPDFTabbedViewController, to show multiple PSPDFDocuments with a top tab bar. iOS5 only. (includes new TabbedExample)
Changed

New feature: PDF page labels are parsed. (e.g. roman letters or custom names; displayed in the PSPDFPositionView and the thumbnail label)
Changed

New feature: send via Email: allows sending the pdf as an attachment. (see emailButtonItem in PSPDFViewController)
Changed

New feature: PSPDFViewState allows persisting/restoring of a certain document position (including page, position, zoom level). See documentViewState and restoreDocumentViewState:animated: in PSPDFViewController.
Changed

Add support for puny code characters in pdf URLs (like http://➡.ws/鞰齒). This uses the IDNSDK.
Changed

New property: useParentNavigationBar, if you embed the PSPDFViewController using iOS5 containment and still want to populate the navigationBar.
Changed

New property: pageCurlDirectionLeftToRight to allow a backwards pagination. (for LTR oriented documents)

Changed

Titanium: New min SDK is 2.0.1.GA2.

1.9.15 - 20 Apr 2012

Added

New delegate: pdfViewController:didEndPageScrollingAnimation: to detect if a scroll animation has been finished. This will only be called if scrollToPage:animated: is used with animated:YES. (not for manual user scrolling)

Changed

Link elements are not shown with exact metrics, and touches are tested for over-span area. Also, over-span area is now 15pixel per default. (old was 5)
Changed

Link elements now don't interfere with double/triple taps and only fire if those gestures failed.
Changed

Link elements no longer use an internal UIButton. (they are now handled by a global UITapGestureRecognizer)
Changed

Annotations are not size-limited to the actual document, no more "bleeding-out" of links.
Changed

Minimum size for embedded browser is now 200x200. (fixes missing Done button)

Changed

Support tintColor property for inline browser.

Changed

removeCacheForDocument now has an additional parameter waitUntilDone. The previous behavior was NO, so just set NO if you use this and upgrade from an earlier release.
Fixed

Fixes a potential cache-loop, where the device would constantly try to load new images.
Added

Adds a sanity check for loading images, fixes a rare issue with images not showing up.

1.9.1 - 17 Feb 2012

Changed

Allow scrolling to a specific rect and zooming: see scrollRectToVisible:(CGRect)rect animated:(BOOL)animated and (void)zoomToRect:(CGRect)rect animated:(BOOL)animated;
Changed

PSPDFAnnotationParser now allows setting custom annotations. (to complement or override pdf annotations)

Changed

PDF cache generation is no no longer stopped in the viewWillDisappear event (only on dealloc, or when document is changed)
Changed

Titanium: Add ability to hide the close button.

Note: For pageCurl, Apple's UIPageViewController is used. This class is pretty new and still buggy. I had to apply some private API fixes to make it work. Those calls are obfuscated and AppStore-safe.

If you have any reasons to absolutely don't use those workarounds, you can add PSPDFKIT_DONT_USE_OBFUSCATED_PRIVATE_API in the preprocessor defines. (only in the source code variant) This will also disable the pageCurl feature as the controller will crash pretty fast when my patches are not applied.

Don't worry about this, I have several apps in the store that use such workarounds where needed, it never was a problem. Also, I reported those bugs to Apple and will keep track of the fixes, and remove my workarounds for newer iOS versions if they fix the problem.

1.8.4 - 27 Dec 2011

Fixed

Fixes a problem where search highlights were not displayed.
Changed

Updated git version scripts to better work with branches. (git rev-list instead of git log)

1.8.3 - 26 Dec 2011

Changed

Update internally used TTTAttributedString to PSPDFAttributedString; prevent naming conflicts.
Changed

Fallback to pdf filename if pdf title is set but empty.
Changed

pageMode can now be set while willAnimateRotationToInterfaceOrientation to customize single/double side switching.
Fixed

Fixes a problem with the document disappearing in certain low memory situations.

1.8.2 - 25 Dec 2011

Fixed

Fixes a regression with scrobble bar hiding after animation.
Fixed

Fixes wrong toolbar offset calculation on iPad in landscape mode.
Changed

Various performance optimizations regarding CGPDFDocument, HUD updates, thumbnails, cache creation.

Lazy loading of thumbnails.

1.8.1 - 23 Dec 2011

Changed

Changed

Annotation page cache is reset when protocol is changed.
Fixed

Fixes Xcode Archive problem because of public header files in PSPDFKit-lib.xcodeproj
Fixed

Fixes a regression with the Web-AlertView-action not working.

1.8.0 - 21 Dec 2011

Changed

Search Highlighting! This feature is still in BETA, but already works with many documents. If it doesn't work for you, you can disable it with changing the searchMode-property in PSPDFDocumentSearcher. We're working hard to improve this, it just will take some more time until it works on every document. As a bonus, search is now fully async and no longer blocks the main thread.
Changed

ARC! PSPDFKit now internally uses ARC, which gives a nice performance boost and makes the codebase a lot cleaner. PSPDFKit is still fully compatible with iOS4 upwards. You need to manually include libarclite.so if you are not using ARC and need compatibility with iOS4. Check the MinimalExample.xcodeproj to see how it's done. (You can drag the two libarclite-libraries directly in your project). If you use the PSPDFKit-lib.xcodeproj as a submodule, you don't have to think about this, Xcode is clever enough to not expose this bug here. See more about this at https://pspdfkit.com/guides/.
Changed

New default shadow for pages. More square, iBooks-like. The previous shadow is available when changing shadowStyle in PSPDFScrollView. The shadow override function has been renamed to pathShadowForView.
Changed

New: PSPDFDocument now uses the title set in the pdf as default. Use setTitle to set your own title. Title is now also thread-safe.
Changed

New Thumbnail-Framework (removed AQGridView). Faster, better animations, allows more options. Thumbnails are now centered. You can override this behavior with subclassing gridView in PSPDFViewController.
Changed

New: HUD-elements are now within hudView, hudView is now a PSPDFHUDView, lazily created.
Changed

New: Page position is now displayed like in iBooks at the bottom page (title is now just title)
Changed

Changed: Videos don't auto play per default. Change the url to pspdfkit[autoplay:true]://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8 to restore the old behavior (or use delegates).
Changed

Changed: viewMode does not longer animate per default. Use the new setViewMode:animated: to change it with animation.
Changed

Changed: the left section of the toolbar now uses iOS5-style leftToolBarButtons if available; falls back to custom UIToolBar in iOS4.
Changed

Shortly pressed link targets are now highlighted with a minimum duration.
Changed

Alert is no longer displayed for URLs that can't be opened by the system.
Changed

Support detection of "m4v" as video annotation.
Changed

Improves performance when caching very large documents.
Changed

Expose the borderColor of PSPDFLinkAnnotationView; set in one of the delegates.
Changed

Removes a lot of glue code and switches to KVO for many view-related classes (Scrobble Bar)
Changed

Add methods to check if PSPDFPageInfo is already available, improves thumbnail speed.
Changed

Add generic support to override classes. See the property "overrideClassNames" for details. This replaces "scrollViewClass" and "scrobbleBarClass" and is much more flexible. Just use a key/value pair of NSStrings with default/new class names and your custom subclass will be loaded.
Changed

setScrobbleBarEnabled is now animatable.
Changed

The protocolString for the multimedia link annotation additions can now be set in PSPDFAnnotationParser (defaults to pspdfkit://).
Changed

didTapOnPage is now didTapOnPageView, the former is deprecated.
Changed

PSPDFPageCoordinates now show a nice description when printed.
Changed

Many deprecated delegate calls have been removed. Check your calls.
Changed

Version number is now directly written from the git repository. (PSPDFVersionString() is now more accurate)
Changed

When a link annotation is tapped, the HUD no longer shows/hides itself.
Changed

HUD show/hide is now instant, as soon as scrolling is started. No more delays.
Changed

Scrollbar is now only changed if controller is displayed in full-screen (non-embedded).
Changed

Fixes a issue where PSPDFKit would never release an object if annotations were disabled.
Changed

Fixes a bug where the outline was calculated too often.
Changed

Fixes an issue where the title was re-set when changing the file of a pdf.
Changed

Fixes problems with syntax highlighting of some files. Xcode 4.3 works even better; use the beta if you can.
Changed

Fixes a bug with video player when auto play is not enabled.
Changed

Fixes encoding for mailto: URL handler (%20 spaces and other encoded characters are now properly decoded)
Changed

Fixes potential crash with recursive calls to scrollViewDidScroll.
Changed

Fixes a rare crash when delegates are changed while being enumerated.
Changed

Lots of other small improvements.

1.7.5 - 1 Dec 2011

Fixed

Fixes calling the deprecated delegate didShowPage when didShowPageView is not implemented. (thanks Albin)

1.7.4 - 29 Nov 2011

Changed

Custom lookup for parent viewcontroller - allows more setups of embedded views.
Fixed

Fixes a crash related to parsing table of contents.

1.7.3 - 29 Nov 2011

Added

Add a log warning that the movie/audio example can crash in the Simulator. Known Apple bug. Doesn't happen on the device.
Changed

PSPDFCache can now be subclassed. Use kPSPDFCacheClassName to set the name of your custom subclass.
Fixed

Fixes a bug where scrollingEnabled was re-enabled after a zoom operation.

1.7.2 - 29 Nov 2011

Changed

Changes delegates to return PSPDFView instead of the page: didShowPageView, didRenderPageView.
Changed

Improve zoom sharpness. (kPSPDFKitZoomLevels is now set to 5 per default from 4; set back if you experience any memory problems on really big documents.)
Changed

Increase tiling size on iPad1/older devices to render faster.
Changed

Reduce loading of unneeded pages. Previously happened sometimes after fast scrolling. This also helps when working with delegates.
Fixed

Fixes a locking race condition when using PSPDFDocument.twoStepRenderingEnabled.

1.7.1 - 29 Nov 2011

Fixed

Fixes a rare crash when encountering non-standardized elements while parsing the Table of Contents.

1.7.0 - 28 Nov 2011

Changed

PSPDFKit now needs at least Xcode 4.2/Clang 3.0 to compile.
Changed

Following new frameworks are required: libz.dylib, ImageIO.framework, CoreMedia.framework, MediaPlayer.framework, AVFoundation.framework.
Changed

Images are now compressed with JPG. (which is usually faster) If you upgrade, add an initial call to [[PSPDFCache sharedPSPDFCache] clearCache] to remove the png cache. You can control this new behavior or switch back to PNGs with PSPDFCache's useJPGFormat property.
Changed

Optionally, when using PNG as cache format, crushing can be enabled, which is slower at writing, but faster at reading later on. (usually a good idea!)
Changed

New multimedia features! Video can now be easily embedded with a custom pspdfkit:// url in link annotations. Those can be created with Mac Preview.app or Adobe Acrobat. Try for example "pspdfkit://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8" to get the HTTP Live streaming test video.
Changed

Link annotations are now UIButtons. This allows more interactivity (feedback on touch down), and also changes the default implementation of PSPDFDocument's drawAnnotations function to be empty. Clear the cache after updating, or else you get two borders. You can also return to the old behavior if you return NO on shouldDisplayAnnotation (PSPDFViewControllerDelegate) anytime an annotation of type PSPDFAnnotationTypeLink is sent.
Changed

Localization is now handled via the PSPDFKit.bundle. You can either change this, or use PSPDFSetLocalizationDictionary to add custom localization.
Changed

PSPDFLinkAnnotation is renamed to PSPDFAnno
