I'm proud to announce the posting of a pre-release of GIMP 2.2.13. This is a multilingual package (an english-only one will be posted as well). This version updates to 2.2.13 and adds in full Vista compatibility. It's also now packaged in PortableApps.com Format.
Also new in this release is the ability to store GTK in a CommonFiles directory. In a standard setup, this would be:
Just be sure to delete the GIMPPortable\App\gtk directory if you use this feature.
Even more significant is a new feature I've added to the launcher that I'm pretty excited about. It's a GIMP plugins pre-processor. It keeps track of where you last ran GIMP Portable from and automatically updates your pluginsrc file. This means that GIMP will start up without having to poll all your plugins each time, even when you move between PCs. It will still index them fully on the first launch, but after that, it won't need to. There is a slightly longer delay before the GIMP splash screen is shown while the launcher pre-processes the file.
Please give it a try and post any feedback.
UPDATE (Pre-Release 2): I added in a default set of settings so that GIMP won't even need to update plugins on first launch (it will if you're upgrading an existing install, though). I also added checking for an in-place upgrade so that it won't get stuck pre-processing the pluginsrc.
UPDATE (Pre-Release 3): I added in a checker to take care of the files that GIMP and GTK leave behind in the %USERPROFILE% directory (.fonts.cache-1, .gtk-bookmarks and the .thumbnails directory) The launcher needs to stick around until close to do it. Oh, and the file is named .paf.exe now (oversight in the PR2 release).
