[…] Version 2.1.1 includes about 30 bug fixes, mostly minor things around encoding, XML-RPC, the object cache, and HTML code. It’s available for immediate download on our download page.
Not only that, WordPress has released a security patch for version 2.0.7 to upgrade it to version 2.0.9:
Version 2.0.9 only includes the security update, which was around the code we use to prevent XSS. […] As a reminder, we’ve committed to proving security updates to 2.0 through 2010, but all new features and development are going into the newer branch, which is at this time 2.1.
I haven’t yet made the jump to 2.1 on this blog (but I did on my sandbox) as I’m still dithering about the K2 theme. There’s also the issue for me re Dreamhost and PHP. Although this blog hasn’t fallen over so far, I really must find time soon to upgrade.
