A message to our WordPress clients.
A new version of WordPress was released on February 23. In an effort to reduce potential exploits, and keep popularly targeted software up to date, we are recommending that all users utilizing this software, upgrade their WordPress installs to version 3.1. We are simply taking the proactive approach to alerting our customers that a new version is available and it is recommended that they upgrade.
If you would like to review the newest notes for the patch, you can review them on WordPress Codex here https://codex.wordpress.org/Version_3.1 .
