2018.1 Migration Guide
PSPDFKit Server 2018.1 adds support for importing and exporting XFDF and Instant JSON files and improves validation of your configuration settings.
Necessary Steps When Upgrading PSPDFKit Server
PSPDFKit Server no longer allows you to use the default
secret-key-base. If you were using the default value, please note that you’ll have to change your configuration. Otherwise, PSPDFKit Server will abort the startup. Take a look at the configuration overview for more information about our configuration options.
When uploading documents, you can include an additional
attachmentfile, which in turn will be imported into the uploaded PDF.
