I’ve been using WordPress for almost 3 years now and implement it in my consulting work as the blog software of choice. Over the years there have been issues with upgrades (like the move from 1.5 to 2.0, for example) but the community always got the new version stable within a few weeks.
While it’s too early to tell at this point, version 2.3 seems to be the most problematic upgrade yet. After taking this blog up on the day it was released, I upgraded my wine blog a few days later. After a week of MySQL errors with plug-ins and various other misadventures, I restored back to 2.2.3 last weekend. I think I’ll stay there for a while but still keep this blog on the latest build to monitor progress.
There’s a lot to like about the new WordPress so I’m hoping Matt and the team get this one stable shortly.
