Although not revealed in the release notes, the release name "Matrix" certainly pays tribute to the previous "The Matrix Trilogy" and the upcoming "The Matrix 4" movie. The Matrix-style visualization of computer screens has been around since "The Matrix" was released in 1999 – and was probably used by every coder at least once in their lifetime.
What's under the hood?
- Improved metadata handling for audio files (dates, album duration, multi-disc sets, etc)
- HDR10 video support across multiple Operating Systems (Windows and Android)
- Screen redesign in the user interface, new "now playing" view, new and updated GUI controls
- Subtitles gets a lot of updated, from changing colors and opacity as well as fixing the timestamp overlay
- For add-on developers: Python 2 is dead, long live Python 3
- The previous XML based metadata scraper is replaced by the new Python scraper (for movies and tv shows)
- PVR (receiving tv or radio signals using a tuner card) tools received a lot of attention: PVR reminders, widgets on the home screen, group/channel manager enhancements, channel numbering and sorting (that was previously always a pain), performance improvements
- Additional security, especially for installation of add-ons: By default third-party add-ons cannot overwrite existing libraries from already installed add-ons, Kodi's web interface is now by default password protected
