Mastodon EngineeringIn case you missed it, Quote Posts are live on mastodon.social and mastodon.online — let us know what you think!
This feature has been a long time coming because we wanted to take the time to do it right. Part of that process was sharing our work and getting feedback along the way.

Mastodon EngineeringWe wanted to share a special thanks with the community members who were instrumental in the design of quote posts.
First, @mekkaokereke@hachyderm.io whose feedback and guidance helped us iterate on Quote Posts to make them safer and more inclusive. Thank you Mekka!

Mastodon EngineeringWe just released Mastodon 4.4.3, 4.3.11, and 4.2.24.
These versions contain bugfixes, a fix for a moderate severity rate limit issue, and security issue if you use SAML. In 4.4.3 there are also changes to how quote posts are handled, as we continue to work towards full support for quote posts in the next main release.
