WordPress 2.2.1 is now available for download. WordPress 2.2.1 is a bug fix release for the 2.2 series. Since 2.2 was released a month ago, the WordPress community has been improving fit-and-finish by identifying and fixing those little bugs that can be so annoying and by fine-tuning some small details. The result is a nicely polished 2.2.1 release. Some of the highlighted bug fixes include:
- Atom feed validation fixes
- XML-RPC fixes
- Widget backward compatibility fixes
- Widget layout fixes for IE7
- Page and Text Widget improvements
Unfortunately, 2.2.1 is not just a bug fix release. Some security issues came to light during 2.2.1 development, making 2.2.1 a required upgrade. 2.2.1 addresses the following security vulnerabilities:
- Remote shell injection in PHPMailer
- Remote SQL injection in XML-RPC
- Unescaped attribute in default theme
The upgrade from WordPress 2.2 to 2.2.1 went smoothly for me. However, I had to go back to the original version of ExecPHP. I had mod the codes in order for ExecPHP to work with 2.2. Since 2.2.1 addressed that bug, my ExecPHP plugin didn’t work until I switch back to the original.
If you’re still on WordPress 2.1, then now would be the time to upgrade to the latest WordPress.
