I have just released new versions of the AWSOM Pixgallery(4.5.3), AWSOM News Announcement(1.4.2), and AWSOM Uninstaller (1.0.2) plugins for WordPress that have been made specifically compatible with the upcoming WordPress 2.5 release (the AWSOM Archive plugin was already fully 2.5 compatible with version 1.4.0). This means that they will install properly and work as they currently do. AWSOM plugin versions previous to these new releases will NOT install properly on WordPress 2.5 due to a major change in their plugin protocol (though I believe that already installed plugins will not stop working, I can’t guarantee that–especially if you deactivate/reactivate them during the WordPress upgrade process).
I will probably come out with another minor release of the plugins after WordPress 2.5 is officially released that does some cosmetic changes to my admin pages for the plugins, but this will have to wait until they finalize the CSS they are using for their admin pages (right now they all look fine, but don’t really match the new look of the admin area in 2.5). For the moment though everything will work properly, so you at least have one less worry if you plan on upgrading to WordPress 2.5 :)
