Bug fix release notes 5.2.1

A bug fix release to version 5.2.1 of the Oxford Mosaic platform was released on 27 April 2023.

Bug fix rolled back

An error in the fix for bug 66850 (see previous release notes) caused the purging of the server cache to fail, resulting in outdated pages displaying and new updates not publishing effectively. Unfortunately this means we have had to revert this fix, but we aim to re-apply it (i.e. fixing bug 66850 without unintended side effects!) in the next release, scheduled for 4 May 2023.
