I've just released version 2.45 of #snac, the simple, minimalistic #ActivityPub instance server written in C. This one includes fixes to some nasty bugs and some interesting contributions:
Fixed a collision in webfinger caching. This may affect federation with some software, so I recommend an upgrade.
Fixed crashes in some command-line options.
New command-line option state, that dumps some information about the running server and the state of each thread (note: this feature uses shared memory blocks and you may need an argument to the make call in older Linux distributions; please see the README file for details).
Fixed a bug that may leave an inconsistent state for a followed actor in a special case of repeated messages.
Mastodon API: added some fixes for integration with the Mona iOS app (contributed by jamesoff).
Added support for ntfy notifications, both using a self-hosted server or the official ntfy.sh (contributed by Stefano Marinelli).
