July 30th, 2011· Previously processed files do not appear in the Dock anymore (in Mac OS X 10.7).
· Fixed a potential crash when processing a par2 set.
July 7th, 2011· The program now works with OS X 10.7 (Lion) as well as Mac OS X 10.6 (Snow Leopard).
April 13th, 2010· Fixed an issue that could cause the program to crash when an incorrect rar password was entered.
January 11th, 2010· Fixed an issue that could cause the program to take a very long time opening a par2 file.
· Added a new post-process macro for command line rules.
· Added an icon for rar documents (becomes visible if you link the “rar” extension to MacPAR deLuxe).
· Upgraded all document icons to large size (512 x 512 pixels).
January 3rd, 2010· This version requires Mac OS X 10.6 "Snow Leopard" or better. It does not run on previous versions of the operating system.
· The program uses Snow Leopard techniques (most notably Grand Central Dispatch) to speed up the par process, and to improve the distribution of the work load over multiple processor cores.
· The program now runs fully 64 bit (on a 64-bit Mac); this goes for the user interface as well as the par and rar engines. It comes as a universal binary, so it runs on 32-bit Macs as well.
· Improved ease-of-use by re-organizing the tool bar, adding more descriptive tool tips, and rewriting parts of the documentation.
· Fixed a few technical issues, improving stability and reliability.
March 20th, 2008· You can now configure a folder where the Unrar results will always be written.
· Added a configuration option for fully unattended operation.
· Added a configuration option to limit the number of CPU cores used for par2 processing. Default is still to use all cores.
· In Mac OS X 10.5 (Leopard) on an Intel Macintosh the par2 process now runs in 64-bit mode, resulting in a slight performance improvement.
· The Quit menu is now disabled while a par or unrar is running. You must explicitly cancel before quitting.
· Before starting the par / par2 process the program now checks if the folder is writable.
· The program no longer runs on Mac OSX 10.3.x (Panther). Supported systems are 10.4.x (Tiger) and 10.5.x (Leopard).
