I was thinking that the next WordPress version to be released would be the 2.9.0, but there is another one from the 2.8 family out there, the 2.8.5. According to the official WordPress blog this is not an urgent upgrade, but it has the goal of hardening your install, so upgrading is recommended. Here are the four main features introduced:
- A fix for the Trackback Denial-of-Service attack that is currently being seen.
- Removal of areas within the code where php code in variables was evaluated.
- Switched the file upload functionality to be whitelisted for all users including Admins.
- Retiring of the two importers of Tag data from old plugins.
Stay tuned for 2.9.0 which should be coming out next month as well. This one should bring some cool new features for WP users.
