Osada being abandoned
Last week Mike MacGirvin posted a message where he announced among other things that Osada will be abandoned. This will probably mean that Osada will seize to function in the next couple of months.
Osada will be spun off (separated from Zap) and officially abandoned. If you want to take over the project, go for it. The implementation of Zot6 there is now frozen because future Zot6 work (and Zot8 - more on that in a moment) will not be compatible with ActivityPub. At all. As far as I know Osada is the only viable ActivityPub server for events and groups, but Friendica and Hubzilla aren't very far off.
