2.0.0-alpha.1

Added

• The new Format API simplifies the detection of file formats, including known publication formats such as EPUB and PDF.
  • A format can be "sniffed" from files, raw bytes or even HTTP responses.
  • Reading apps are welcome to extend the API with custom formats.
  • Using Link.mediaType?.matches() is now recommended to safely check the type of a resource.
  • More details about the Swift implementation can be found in the pull request.
• In Publication shared models:
  • Presentation Hints and HTML Locations extensions.
  • Support for OPDS holds, copies and availability in Link, for library-specific features.
• (Experimental) Audiobook toolkit:
  • AudioSession simplifies the setup of an AVAudioSession and handling its interruptions.
  • NowPlayingInfo helps manage the "Now Playing" information displayed on the lock screen.

Changed

• All the Publication shared models are now immutable, to improve code safety. This should not impact reading apps unless you created Publication or other models yourself.
• The DocumentTypes API was extended and offers an easy way to check if your app supports a given file.
• Dependencies to format-related third-party libraries such as ZIP, XML and PDF are being consolidated into r2-shared-swift. Therefore, r2-shared-swift now depends on Fuzi and ZIPFoundation. This change will improve maintainability by isolating third-party code and allow (work in progress) to substitute the default libraries with custom ones.
