THIS MEANS THAT PLEROMA NOW SUPPORTS FEDERATION OVER ACTIVITYPUB.
Before upgrading, please read through https://blog.soykaf.com/post/activity-pub-in-pleroma/. The needed migration can take a LONG time (up to a few hours, although probably just some minutes), so expect some downtime.
If you experience problems or encounter bugs, please report them at https://git.pleroma.social/. There will probably be some, but we'll fix them fast.
@lain On my fairly beefy hardware I was seeing ~10-15 seconds for every 10k activities that needed to be modified. Not too bad. I have been on here for about 6 months and had 350,000 activities. Under 10 minutes to do the migration.
It's possible this could go faster if you increased your work_mem in Postgres up from the default 4MB to ... maybe 8MB? But you might not want to keep that permanently as you will see much higher memory usage.
