I was hoping I could get some pointers or advice about what I assume are several different "branches" of WordPress. I've browsed the forums and trawled through the release announcement posts and I'm just not sure what the difference/advantage is to having 2.0.x, 2.1.x, or 2.2. I saw that 2.0.x will be maintained until 2010, but will 2.1.x be supported? Can anyone explain it, or is there a link to somewhere I could read about it? I've been told off :-) for having 1.5.31. I know I need to upgrade, but I'm so out of date I don't even know which one!
Here are the specs of my host:
PHP Version 4.4.1
mySQL Version 12.22 Distrib 4.0.27
Very much appreciate the help!
