19.0.25 (8/12/2013)
1. NEW: Added support for user accounts that are stored with the library and allow each user to see only certain files (replaces Access Control feature).
2. NEW: Added a 'User' library field that can be set to any combination of users to limit the contents visibility to only those users (leave blank for content to show for all users).
3. SDK: The MC command MCC_BACKUP_LIBRARY (20011) will perform a silent automatic backup when passed "1" as the parameter.
4. Changed: The program will run the automatic library code periodically instead of only at program start (so that running the program for long periods won't stop automatic backups from happening).
5. Changed: Auto-import has separate options for analyzing audio for audio and video files.
6. NEW: User can choose a time for MC to load television EPG in background.
7. Changed: Server token authentication persists across a server restart so that an authenticated client won't be forced to reconnect if the server goes down and comes back up.
19.0.24 (8/9/2013)
1. Fixed: The audio analyzer was not properly returning per-channel peaks.
2. NEW: JRSS downmixing uses per-channel peak levels from audio analysis when they're available to make a better determination about how much (if any) volume reduction is required to prevent clipping after the downmix.
3. Changed: The 'Volume Up' and 'Volume Down' roller items do not appear in Theater View when the volume is in disabled mode.
4. Changed: The error check during WPD camera acquisition makes sure the source and destination file sizes are within 2.5% instead of an exact match since some devices do not expose an exact file size (Android 4.3 in MTP mode).
5. Changed: Doing a Camera acquire shows a playlist 'Recently Acquired' that contains only images acquired in the last hour (like other recent playlists, it is automatically cleaned up after a few days).
19.0.23 (8/8/2013)
1. Fixed: When non-analyzable files were added to the analyzer, the program would dead-lock when showing the error dialog.
2. Changed: Added int(...), frac(...), round(...), and trunc(...) to the math evaluator (used in expressions, visualizations, etc.).
3. Changed: The math evaluator is double-precision (64-bit) instead of single-precision (32-bit) for floating point operations.
4. Changed: The option to not draw frames on image thumbnails is honored in grouped details lists (previously it was only honored in thumbnail lists).
5. Fixed: File creation could fail in build 19.0.22, causing several possible strange problems.
19.0.22 (8/8/2013)
1. Fixed: Importing of mp4 files that have copyright atom could cause MC to crash.
2. Changed: Vertical scrollbars are positioned inside the column header in a list instead of over it (allows a cleaner look with some skins and is logical since the column header doesn't scroll).
3. Fixed: MC could fail to load ID3 tag data in AIFF and WAVE files.
4. Fixed: MC did not write copyright tag to mp4 files.
5. Changed: MC will try reading copyright tag from a second location in mp4 files if the ISO-defined 'cprt' atom does not exist.
6. Changed: The list editing widget (used for editing keywords, etc.) puts the 'Add' box at the bottom and moves the instructions into the box for a cleaner alignment and less chance for the suggestions when adding to obscure the existing list.
7. Faster: File I/O adds a buffering layer that engages when small reads are performed so that underlying reads are never too small (a real world example where this helps is with FLAC playback over some types of wireless networks).
19.0.21 (8/7/2013)
1. Changed: The audio analyzer considers a file analyzed if it has a 'Volume Level (R128)' and 'Peak Level (R128)' value.
2. Faster: Analyzing files to decide what playback / decoding method to use is faster (makes opening the Analyze Audio dialog with lots of files faster).
3. Fixed: Files with a peak level of 0.0 dB could incorrectly be marked as needing analysis.
4. Changed: The standard ReplayGain volume level and peak level tags will not be written to tags if tagging is turned off for the corresponding MC fields 'Volume Level (ReplayGain)' and 'Peak Level (Sample)'.
