Sentry 8.2.2 / 8.1.4 is a security update. Code execution vulnerability that's only exploitable by Sentry superusers, so nothing too urgent.
8.2.4 / 8.1.5 is another security update. "If being run in multi-organization mode, it was possible for a user to craft a URL which would allow them to view membership details of other users." - not a big deal.
Gilles has pointed out that Sentry 8 dropped MySQL support. Our PostgreSQL puppet roles need a lot of love, so this upgrade will be a big task.
This task has been assigned to the same task owner for more than two years. Resetting task assignee due to inactivity, to decrease task cookie-licking and to get a slightly more realistic overview of plans. Please feel free to assign this task to yourself again if you still realistically work or plan to work on this task - it would be welcome!

(For the records, two emails were sent to assignee addresses before resetting assignees. See T228575 for more info and for potential feedback. Thanks!)
