Time for a new release of WordPress. WordPress 2.3 brings a long awaited feature, actual tags instead of categories. Word so far is that they are quite basic, and that the underlying tables for WordPress are quite different to cater for them, so it is quite possible that it could break plugins you have in existing installations. This is the good thing about hosting WordPress on your own webspace though, you can test it out properly. I have a few blogs, including a test blog. On the test blog, I can run upgrades like this, having turned all the plugins off, then turn them back on one by one to see that they works. Saves a lot of time debugging. Since WordPress can be such an easy install, it’s really worth having such a testbed.
For more information about WordPress 2.3, I’d really reccommend listening to Lorelle Vanfossen on the latest episode (#29) of the WordPress Podcast. They really get into a good level of detail about what you can expect, and what issues you need to be aware of. I’ve installed a few .1 advances of WordPress before with various levels of success (usually good to be fair), but having listened to this in detail, I’m feeling more cautious, and will test properly first this time. I’m probably a couple of weeks away from having chance to do this, but when I do, I’ll review the process and show my workings.
