The ActivityPub application 1.7.2 fixes two issues discovered in ActivityPub 1.7.1.
The most important fix addresses a compatibility issue with Mastodon v3.3.0, which improved its incoming requests validation. We updated the sent HTTP headers to align ourselves with Mastodon’s expectations.
The fix addreses an issue where the list of followers was always displayed as empty after a follow action.
