concrete5 188.8.131.52 is a small maintenance release fixing a couple upgrade issues and an issue with older PHP installations that lack PDO MySQL that was originally required with the new queue engine. There are also some nice Select Attribute UI improvements as well as general cleanup and bugfixing thanks to the awesome concrete5 developer community. This release is recommended for all users of concrete5.
Available for immediate download.
