Today we noticed a critical bug in yesterday's 2.2.5 release so we've put out an extra release (2.2.5.1) today.
The bug appears as errors like this:
Error Writing to database.Debug info: Column 'useridfrom' cannot be null
It can turn up in a few places but particuarly when interacting with programs.
If you have already upgraded to 2.2.5 we recommend that you upgrade to 2.2.5.1 or any subsequent release to receive the fix.
If you haven't yet upgraded, we suggest skipping 2.2.5 and upgrading directly to 2.2.5.1 or any subsequent release.
Sorry about that!
Simon
