It had taken me a few days to get round to it when today I see that the little paragraph at the bottom of the blog entry was slightly off, though hedging their bets with the word “probably”.
As a side note, this is probably our last release before 2.1 is out, which will be our first major feature release in quite a while. WordPress
As 10 days later v2.0.7 is out, because of some faults.
Recently a bug in certain versions of PHP came to our attention that could cause a security vulnerability in your blog. We’re able to work around it fairly easily, so we’ve decided to release 2.0.7 to fix the PHP security problem and the Feedburner issue that was in 2.0.6. It is recommended that everyone running WordPress 2.0.6 or lower upgrade to this new version. WordPress
Lucily it doesn’t require a full delete and replace update of all the files just the following.
