Over on the Upgrading WordPress with Fantastico post Francois asked “Do you think it is really necessary to upgrade in the first place?”
Well, the short response is that after reading a number of posts from webmasters who have done the WordPress 2.5 upgrade, I'm more inclined to believe that my penchant for keeping things simple really pays off. (Although I'm already using WP 2.5 on a couple of smaller, very simple blogs; I haven't yet updated my larger blogs such as NPT).
WebBlogToolsCollection has posted a FAQ on WordPress 2.5 that answers a big whack of questions about the new version, and many of the 67 commentors to date have added still more questions to the already sizeable list.
The biggest complaint around the blogosphere seems to be that the widgets don't work for some bloggers who use multiple column templates. One might assume that they are using templates not yet verified as being compatible with WP 2.5. However, even templates that were listed as compatible on the WordPress site were later discovered not to work completely with the latest version.
Ergo, my statement about simplicity above. I don't bother using widgetized sidebars and prefer instead to hardcode elements so that they will work regardless of template compatibility… and goodness knows that I like to tinker with templates! 🙂
So, to answer your question, Francois — if you are uncertain about whether or not you should upgrade at this point, it's probably best to wait — especially if you're not big into tweaking and want something that works ‘out of the box'.
Here's some sage advice that Jon of Ninja Blog Setup left as a comment on the earlier post:
For major upgrades, like the one just released from 2.3.3 to 2.5 it is advisable to wait a couple weeks to allow plugin authors a chance to test and revise any problems in their plugins, but with minor upgrades, like from 2.3.2 to 2.3.3, which are often security related, these should be done ASAP and the Instant Upgrade plugin works fantastically.
