Support for MacOS Catalina. Further optimizations.

Temporary Fix for AirPlay support in macOS High Sierra Now requires OSX 10.8 or higher.

Minor optimizations to the playback engine. Fix an uncommon crash when playback stops or transitions between tracks. Fix a crash during playback for certain kinds of DAC.

Significant optimizations to the Gen-IV audio engine, resulting in a subtle improvement in sound quality. Fix for an intermittent crash on certain DACs.

Fix crash when playing DSD256 hybrid files on incompatible devices.

DSD256 Support

Fix crash caused when a brief dropout is encountered when using AirPlay. Fix occasional crash when stopping or starting playback.

Several bug fixes. :)

New Generation-IV 64-bit audio engine. Fixes problems with most multi-channel DACs. Support for iTunes Sound Check. Improved integration with iTunes. Support for OS X Dark Mode. Audio Output Device selection from drop-down menu. Menu Bar icon colour now indicates playback format. Visible confirmation of Integer Mode playback. Improved automatic detection of Access Permissions. Many minor bug fixes.

Triple-buffering in the Audio Engine (replaces double-buffering). Some minor additional optimizations to the Audio Engine. Some improvements to internal diagnostic messages. Fix problem where currently-selected audio device's DSD capability is ignored when DSD support is enabled. Mute the hardware when software volume is 0. Fix problem where volume adjustment comment is case sensitive. Improved format matching logic. Eliminate causes of sudden crashes.

Various bug fixes only. This version will NOT run under Snow Leopard.

Native DSD Support ("DSD Master" Required). Fix for non-responsive iTunes Volume Control with 24-bit audio. Gen-III Audio Engine. Preferences Window layout revised. Some minor bug fixes.

Fix looping/skipping caused by iTunes communication problems. Ready for OSX Mavericks.

iTunes 11.0.3 compatibility Fix ends of songs being cutoff in some cases

Fix to correct for channel reversal in AirPlay devices. Option to limit maximum sample rate. Option to reverse channels on individual tracks.

Add volume adjustment iTunes comment Respect iTunes track start/stop times Allow device volume adjustments when not playing Add option to globally apply'fixedindexing' comment. Add option to globally apply 'invertpolarity' comment. Disable playback of CDs in BitPerfect

Automatic bit depth now matches source Add option for maximum bit depth Fix BitPerfect not handing control to iTunes for radio Correctly interpret non-standard Sound Check info (iVolume for instance) Do not play unselected files in playlists

Fix a problem with BitPerfect choosing the wrong bit depth or sample rate with certain DACs. Fix a problem with bit depth limiting on certain DACs.

New 64-bit playback engine guarantees maximum sound quality New SoX powered sample rate conversion options Uses maximum bit depth of the audio device to ensure best possible sound quality Option to use dithered bit depth reduction Support for 'invertpolarity', 'monophonic' and 'donotupsample' iTunes comments Bug fixes from previous versions

Improve handling of corrupt files (play as much as possible) Add log message for CPU overload Add configurable maximum upsampling rate Make volume slider in BitPerfect menu use a decibel scale (when possible) Reduce occurences of skipping and stuttering when using optical DACs Show menu automatically on first load Auto select default device (when appropriate) Disable "Use Maximum Device Buffer Size" by default Fix potential crash on 32-bit systems Fix distortion on certain devices (ex: EMU-0404) Fix gapless playback problem on nuForce Icon HD Fix BitPerfect volume not matching expected levels iTunes levels Fix attempting to upsample over the maximum supported rate (192 kHz) Fix crash on complex DACs Fix sample rate read incorrectly on certain files Fix Integer Mode problems on certain DACs (Light Harmonic, Calyx, Stello U3)

Fix not switching tracks on shuffled playlists Fix slight gapless playback glitch on complex devices

32-bit Support About dialog Reduce chances of skippping/stuttering while performing tasks in iTunes Sound quality optimizations for certain DACs (ex: Metric Halo, Wyred4Sound) Do not try to play DRM protected files Release exclusive mode on unsupported files Queue next track as early as possible (helps with gapless playback over wireless networks) Fix not setting sample rate correctly on certain DACs (ex: Metric Halo, Wyred4Sound) Fix Integer Mode producing static on certain DACs (ex: Metric Halo, QB-9) Fix choosing incorrect sample rate when the unsupported rate is less than the maximum supported by the DAC
