I've just added it on there but notices a couple of things to follow up - which I'll fill in once this is submitted.

So far I've encountered 3 things

1. slowish upgrade 'changing' the log table for civicrm_activity_contact on contact_id field with no real change
2. jenkins test fails due to new version defaulting to emoji friendly db set up & one of our extensions not being good with that.
3. another error I'm just checking out
