WordPress came out with a major update a couple of days ago. The previous version of WordPress (4.4.2) had some critical security issues. Usually security bug fixes are applied automatically, however since there was a new major release, version 4.5 (and subsequent version 4.5.1) had to be applied manually to 4.4.2. I spent most of the weekend upgrading the remainder of the 100 or so odd websites we host on WordPress. Got them all done. 

     If your ministry is on an older version of WordPress, you may want to consider going in and getting the upgrades done. My log files are showing a lot of hacking attempts over the weekend.
