I upgraded my blog to WordPress 2.0 this afternoon, and everything seems to be running very smoothly. All of the plugins that I use still work fine, including CoppermineSC (see more detail on that below). My theme still works, too, which is nice since it took me a while to get it just the way I like it. After upgrading my blog, I also updated Joy’s, and it went just as smoothly.
My CoppermineSC plugin still seems to work correctly with WordPress 2.0. However, I am still running Coppermine 1.3.x, and I’m not sure if the plugin is compatible with the new Coppermine 1.4.x or not. I intend to upgrade to Coppermine 1.4.x as soon as I can, but they have significantly changed how their themes work, so I have a lot of updating to do before I can switch to the new version (I currently have four Coppermine galleries, all running different heavily modified themes).
If I have any trouble after upgrading to Coppermine 1.4.x, you can expect a new version of my CoppermineSC plugin to be released in short order.
