v3.0.1

• Fixed inconsistencies in tab output formatting

v3.0

• Massive internal rewrite:
  • Source code is now purely C++ instead of mixed C/C++
  • Text formating and output now utilize the fmt library, which is safer and typically faster than C stdio implementations
• Easy Mode multithreaded now generates scan jobs per-directory instead of per-file, which provides an approximately 15-20% performance boost due to reduced thread idling time
• Added progress updates for Easy Mode multithreaded
• Added -m MAX option to use the maximum concurrent threads value provided by the OS
• Fixed a critical bug inherited from loudgain where the program segfaults when trying to delete tags from M4A or WMA files
• Added -t option which allows users to choose between sample peak and true peak for peak calculations. Sample peak now default in both Easy Mode and Custom Mode
• Added -O option in Easy Mode which outputs a .csv spreadsheet scan log in every scanned directory
• Added more statistics to Easy Mode output
• Write uppercase tags by default for all tag types in Easy Mode
• Optimized scan progress bar, resulting in significant speed boost for Windows single threaded scanning
• "Overrides" feature renamed "Preset"
  • Specified with -p instead of -o
  • Support preset name as argument, which will automatically find the preset in the predetermined location(s) per platform
  • Support "Global" section in preset, which allows the user to specify settings for all formats to reduce duplication
  • Changed the name of setting keys in accordance with command line flags
  • Ship EBU R 128 preset and "loudgain" preset based on rgbpm settings
• Removed tag modes that enabled non-standard behavior:
  • -s e mode which wrote non-standard REPLAYGAIN_REFERENCE_LOUDNESS and REPLAYGAIN_*_RANGE tags
  • -s l mode which wrote non-standard LU units to *_GAIN tags instead of dB
• Changed how target loudness is specified:
  • Removed -d option which specified a "pre-gain" from -18 LUFS
  • Replaced with -l option which allows the user to specify the target loudness directly in LUFS
• Write ID3v2.3 tags by default in Custom Mode
• Changed clipping protection:
  • Now specified with -c and 3 choice character option instead of a boolean
  • Old -k functionality is now -c a
  • New -c p functionality only provides clipping protection for positive gain values, which is now the default in Easy Mode
• Removed strip tags option (-S)
• Changed max peak level command line char from -K to -m
• Changed behavior for Opus files:
  • Introduced -o option with required char argument
  • Support writing to header output gain
  • default 'd' mode: Write standard ReplayGain tags, set output gain to 0
  • 'r' mode: Write RFC 7845 R128_*_GAIN tags, set output gain to 0
  • 't' and 'a' modes write the track gain and album gain to the header output gain, respectively
  • Keep default loudness at -18 LUFS (can be changed with -l option)
• Windows: Added resource file containing VERSIONINFO
• Windows: Support static linking of dependencies
• Linux: Enforce a minimum taglib version 1.12. Provide a static taglib build for the .deb package

v2.0.1
