ComicPress 2.5 should be released some time this week. If you would like to preview the release the beta is available for download here. Testing it out will help make sure its a solid release so your participation is appreciated.
The major goal of this release is to make customizing it a lot easier and more solid as well as updating to the latest features of WordPress 2.5. The final release will come with multiple layouts as well as the release of a new plugin for mass-posting comics (past or future) based on a folder of image files and their dated filenames. This will make switching over large archives a lot more painless.
