Why You Need to Upgrade to WordPress 2.8.5

Posted: 21 Oct 2009 01:58 AM PDT

Yes, WordPress just released another update — WordPress 2.8.5. Everyone should upgrade your WordPress blog to the latest version. Why?

The latest release will secure and protect your WordPress blog from hackers. It is not 100% bullet proof but hardening your blog security.

Here are the highlights in the new release:

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.

How to upgrade WordPress, the easy way

My first choice would be the WordPress Automatic Upgrade.

When you see the WordPress upgrade notification on WordPress Admin (you might need to logout and login to see it), just follow the instruction to do the automatic upgrade.

However, some web hosting company does not support the automatic upgrade feature…

If that’s your case, then you can FTP upload and replace the modified files since the WordPress 2.8.4 (and only 2.8.4!).

Lastly, you need to download the complete WordPress installation set, unzip it, upload and replace your existing WordPress files, then run the upgrade script (/wordpress/wp-admin/upgrade.php).
