I guess this is something of a cautionary tale.
The weekend before last we decided that it was time to update the WordPress installations on two of our five sites. Both sites had been using version 3.4.2 which was now a year old. Days earlier, WordPress had released 3.6.1, urging all users to update due to some serious security issues. Although it wasn’t clear that this affected the version we were using, we decided to go ahead and update. It was time.
That Friday night, in the wee hours of Saturday morning actually, I upgraded If This Be Treason, our less trafficked site. I began by checking all of the plugins to make sure they were good-to-go with WordPress’ latest and greatest and then updated all that had newer versions available. Except for one, all of the plugins used by that site indicated they worked with at least 3.6.0, which was good enough I figured, since 3.6.1 was only days old and was primarily a bugfix and security release, otherwise no different than the earlier point version.
