I have upgraded my WordPress installation to Version 2.0.5, which was released hot and fresh from the WordPress oven on Friday. All of this site’s content, however, remains old and stale.
Note that both WordPress 2.0.5 and WordPress 2.0.4, which I skipped (probably mainly because I was not paying close enough attention to WordPress releases, but also at least a little bit because I remembered all of that broken link business and I did not want to risk breaking anything that was already working), include security fixes, so anyone running an older version should consider upgrading as soon as possible.
As far as I have seen, everything is running as it should be. Please let me know if you encounter any problems or oddities.
