Reduced the risk of long-running PostgreSQL transactions during federation processing. Federation inbox handlers and remote actor post imports no longer wrap remote post/account persistence in explicit transactions, which could otherwise stay open while fetching remote ActivityPub objects, preview cards, and media attachments. This should reduce
INSERT waitingpile-ups and improve resilience when remote servers are slow or unresponsive. [#411] -
Fixed a bug where timeline markers hadn't allowed partial updates. [#412 by Nicole Mikołajczyk]
-
Fixed a Mastodon API compatibility bug where some serialized statuses had emitted
nullmention URLs or unsupported attachment types, which could break rendering in Moshidon custom lists. Mention URLs now fall back to the account IRI, and unsupported media types are normalized tounknown. [#414]
