Security updates keeps us busy during festive holidays again. The last one with WordPress 2.3.2 kept us occupied prior to the 2008 New Year. Today, the new WordPress 2.3.3 release happens just prior to the Lunar New Year. The major focus of this security release is to fix a flaw in the XML-RPC implementation. Other XML-RPC problems were also plugged in the previous WordPress release. Holidays or not… you should try to upgrade ASAP! More details on 2.3.3 here.
