v4.2.22 
We just released Mastodon 4.3.9 and 4.2.22. They contain a number of important bug fixes, and one security-adjacent fix.
If you are running nightly versions, an updated container image is available under the `nightly.2025-07-02` tag
Full release notes and update instructions are available on our GitHub release page:
Mastodon Admins, you may want to switch your servers to "Approval required to sign up" and perhaps ask for a reason for joining. You can do this at Preferences > Administration > Server Settings > Registrations
There is currently another big wave of scam posts on the Fediverse pretending to be Mastodon support accounts.
All of these scam accounts are on servers that apparently allow instant sign-ups. It would help to stop these scammers if servers can switch to requiring approval.
Tech Note Of The Day (TNOTD):
If you're now on an instance that's been upgraded to the v4.4.* Mastodon distro series, you may want to set your Quote Posts visibility
NOTE: no one can *create* Quote Posts now, this is just in preparation for the v4.5.* distro upgrade
So, at
Preferences (now down at the bottom of the right column) --> Other
find "Who can quote" and set to your preference
I've set mine to "Only your (my) followers"
Note: "This setting will only take effect for posts created with the next Mastodon version, but you can select your preference in preparation."
BE SURE TO SAVE CHANGES
Carry on as you were
