- This will be the last release to support 10.7 to 10.11. This version is still compatible with the latest version of macOS (10.15 Catalina) at the time of release.
- Album gain now displays progress in some situations.
- Bug fixed: Album gain never finishes for large albums.

- Known Issue: Dark Mode is not available on macOS 10.14 or later in this release.
v2.3.1 (Using MP3Gain 1.5.2 with AACGain 1.9.1) -- 2019-12-15
- Albums are no longer processed twice. Status is no longer provided for Album mode.
- Critical Bug fixed: AACGain 1.9 would delete AAC (m4a) files that could not be processed. They are no longer deleted and instead get marked as not supported.
v2.3 (Using MP3Gain 1.5.2 with AACGain 1.9) -- 2018-11-21
- MP3Gain Express 2.3 has been notarized for macOS Mojave's Gatekeeper feature.
- The application has been translated into German by Hans-Juergen Merkel.

v2.2 (Using MP3Gain 1.5.2 with AACGain 1.9) -- 2018-09-24
- Uses the built-in dark mode on macOS Mojave 10.14 or later. (Dark mode is still supported on macOS 10.11 and later)
- An updated Spanish translation was provided by Emilio Pérez Egido.
- The Add Files dialog now prevents you from selecting files that are not MP3 or AAC.
v2.1 (Using MP3Gain 1.5.2 with AACGain 1.9) -- 2017-10-07
- Brand new application icons, designed by George Leventidis
- Added a Greek translation, also contributed by George Leventidis
- Bug fixed: Toolbar customization was not being saved.
- Bug fixed: Dark mode was incompatible with the Increase Contrast accessiblity setting. Increase contrast now disables dark mode.
- Bug fixed: The application could crash in scenarios where an MP3Gain process could not launch when processing a large number of files. This should no longer cause a crash, and the application will attempt to process any files that failed in this manner once more after the rest of the files have processed.
v2.0.1 (Using MP3Gain 1.5.2 with AACGain 1.9) -- 2017-06-23
- Bug fixed: When using Album gain, the volume change was applied to the first file twice.
- Bug fixed: Fixed crash on launch if using OS X 10.10 and dark mode was enabled. The window style used by dark mode was not added until OS X 10.11, so MP3Gain now only matches the menu bar style if running on OS X 10.11 or later.
v2.0 (Using MP3Gain 1.5.2 with AACGain 1.9) -- 2017-06-18
- Added Album Gain support.
- Added AACGain (.m4a / .mp4 audio) support.
- Added multi-threaded processing to process multiple files at once. To accomplish this, the backend has been replaced and AACGain is now executed using separate processes in the background.
- Added a warning message for new users.
- Added a preferences dialog with the following options:
- You can specify how many files are processed concurrently. This defaults to 4 on any machine with 4 or more cores, otherwise it defaults to 2. The maximum that this can be set to is the number of logical cores in your machine.
- The last used volume settings can be saved. This is enabled by default.
- Check for updates can now be enabled or disabled.
- Failures when processing no longer display an error dialog. Instead the file list will indicate bad files after all files have been processed.
- When using dark mode on macOS 10.10 or later, the MP3Gain Express UI will also be dark to match.
- New icons that match the flat style of macOS 10.10 and above.
- Added validation to the volume setting, so users do not enter a value that would definitely produce a bad file.
- This version fixes a crash on application startup when using the macOS 10.13 High Sierra developer beta and "Check for updates" is enabled.
- Note: This release is a 64-bit application and it should continue to work when Apple removes support for 32-bit apps from macOS in 2019.
v1.2 (Based on MP3Gain 1.5.2) -- 2014-11-09
- You can now drag and drop files or folders into the list to add them.
- Now requires OS X 10.7 or later.
v1.1.1 (Based on MP3Gain 1.5.2) -- 2013-02-02

v1.1 (Based on MP3Gain 1.5.2) -- 2013-02-01
- Bug fixed: When processing files with long path names, the files may become corrupted. Note: Backing up your files before processing them is always a suggested practice until you're comfortable that the application is working correctly for you.
- The Add Folder feature can now look inside subfolders, the number of folders deep is selectable.
- A "Prevent Clipping" checkbox has been added. If checked and increasing the volume of a file would cause clipping, this will automatically use the highest volume before clipping would occur.
- Added undo feature, which allows restoring a file with gain applied back to its original volume. This feature is found under the menu next to the apply button.
