We’re so close to WordPress 2.8 I can almost taste it. Release Candidate 1 was released a few days ago and if all goes well, it will finally get released tomorrow (Wednesday). Software goes through a number of cycles before it gets released and a release candidate is the final step before the final version is released. It all depends if anyone finds any problems with the release. If none are find, this will be the final version. If any show stoppers are found, there may be another Release Candidate before the version is finalised.
At least software has the advantage that it can be replaces quite easily. If we were talking about a piece of hardware like one of those PS3 players, once people buy those pieces of kit, it’s pretty hard to upgrade the software to a new version. It gets easier as technology improves, but software is still loads easier to manage and WordPress has the technique down to a T. Now that WordPress lets you upgrade its core files, it’s plugins and now even its themes with just one click, it’s so much easier to handle upgrades.
