- Fixed bug that could cause crash when running many tasks at once.
- Added progress indicator when tagging files.
- Disabled option in preferences to remove padding when writing flac tags until I track down the cause of a bug that could cause the flac files to become corrupt (possible bug in TagLib or metaflac).
- xACT is now 64 bit only. Apple's Xcode 5.1 removed support for applications using Garbage Collection, so upgrading the application to use Automatic Reference Counting forced xACT to be 64 bit only. v2.25 is the last 32 bit app that will work on 32 bit Macs.
2.26 (build 6465) - 04/28/2014
- Fixed bug where st5 files weren't being written.
2.25 (build 6406) - 02/10/2014
- Replay Gain now set by directory. If you feed xACT files in different directories and tell it to add replay gain, it’ll treat the files in each directory as a separate file set.

- fixed bug when converting flac files to aiff and copying tags. If conversion failed, xACT would crash when trying to write tags.
- added Album Artist tag to tags tab and rearranged the placement of tags on the screen
- Added option in preferences to remove padding when adding flac tags. Flac pads tags by default, so if you remove album art, the file size does not decrease. xACT can remove this padding.

- Tags tab now shows common tags if multiple files selected.
- Apple Lossless > AIFF copies tags
- When tagging files, if the selected files contain no album art tag and are all in the same directory, xACT will look for a single image file in that directory and prompt the user to use it. If there are multiple images in the directory, xACT will not try use any image.

- on the Tags tab, added a button to use the previously saved tags. This button will only become visible after you've set some tags since the application launched.
2.17 (build 5156) - 04/29/2012
- Should work in Mac OS X 10.5 again. (the latest version of Xcode doesn't seem to make a 10.5 compatible version even though it says it does)

From the "FLAC/M4A Tags" tab, select "Load Tags From CUE sheet…" from the File menu and choose a cue sheet. xACT will attempt to parse the metadata from the file. Note: previous "Load track Names from file" was moved from the Edit menu to the File Menu.

- Added ability to parse an info text file for track names. From the "Track Name Input" window, select "Load Names From File" from the edit menu and choose a text file. xACT will attempt to parse track names in the file. It looks for lines that start with some variation of a track number: 01 or  or (01) or [01.] etc. Note: this function is incomplete, very basic, and won't work for all cases.
