The builds 50-56

15.0.56 (6/7/2010)

1. Changed: Added PlayingNowPosition, PlayingNowTracks, and PlayingNowPositionDisplay variables to MCWS/v1/Playback/Info function.

7. Changed: Import of document title, keywords, etc. from the filesystem better handles UTF-8.
8. Optimized: Loading the default 'Artists' view with a huge library is about 5% faster. (speed increases should help smaller libraries and other views as well)

15.0.55 (6/7/2010)

1. Changed: Media Type specification for DVB-T television's MPEG-2 audio and AC3 audio is updated.

4. Fixed: WebRemote did not work nicely with Library Server authorization enabled.
5. Fixed: Quicktime files (mov, qt) could not be thumbnailed if they were set to play in DirectShow.
6. Changed: When playing files externally to MC (i.e. double click a file in Win explorer), windowed playback is now an option in General options.
7. Changed: Improved DLNA track advancement system to be less dependent on DLNA events. (events are used to help performance, but system functions fine even if device doesn't event properly)
8. Fixed: Webpage style stores would just show 'Installing' instead of a webpage. (since build 51)
9. Fixed: Theater View > Playing Now > Info view would not advance properly as tracks changed.

15.0.54 (6/3/2010)

6. NEW: Added Russian translation.

15.0.52 (6/1/2010)

1. Fixed: Playing different audio file types consecutively without clicking the stop button could cause some audio types to output noise.
2. Fixed: The background behind a video would be glass instead of black when using a glass-enabled skin.
3. NEW: Library Server, WebPlay, and WebRemote use a token-based authorization system so that once a client is authorized, it won't have to authorize again on subsequent requests. (fixes issues using Gizmo with authorization enabled, etc.)
4. Changed: List management windows no longer hide their list when disabled now that lists can nicely render a disabled state (applies to Options > Network, etc.).
5. Changed: Revised naming and versioning of Gizmo Android application.
6. Changed: WebPlay and WebRemote no longer show Play, etc. buttons at the view scheme level.
7. Changed: Reversed change #6 in build 51.

3. Optimized: Improved caching of server hits done by Performer Store for better performance.
4. Changed: Playing a Performer track from the local library (or Playing Now) will login so that full length version is played.
5. Fixed: Fixed possible dead-lock from audio engine parallelization improvements of build 50.
6. Changed: Television will try using generic Microsoft Network Provider filter first, instead of individual ATSC/DVB-T Network Providers.
7. Fixed: Making changes to Playing Now just as a song was ending (and the next track was prebuffering) could cause the visual play indicator to disappear.
8. Fixed: The 'Media Editor' start menu shortcut was not working (will recreate start menu group at stock location; later upgrades will not).
9. Fixed: Converting multiple audio files to mp3 did not work properly due to temporary filename conflict.
