Hi everyone,
The ActivityPub application 1.7.1 fixes a bug discovered in ActivityPub 1.7.
This bug was preventing content received from the Fediverse, for instance from some Mastodon servers to be handled property. One of the consequence was the impossibility to follow the users of some Mastodon servers.
The full release notes is available at https://www.xwiki.org/xwiki/bin/view/ReleaseNotes/Data/ActivityPub%20Application/1.7.1/
Enjoy.
