Upgraded my Mastodon instances to v4.3.4 from v4.3.2 finally.
With containers it's relatively painless.
That said, I really would like the Mastodon admin interface have settings for post lengths and number of poll items.
It's a bit of a pain to vet and correct whether ./app/javascript/mastodon/features/compose/containers/compose_form_container.js, ./app/validators/status_length_validator.rb, and ./app/validators/poll* need to be changed/updated/migrated for every new minor release. Not a big deal, truly, but it is something to fat finger and something else to track in your environment.
Mastodon is fabulous and complex but a little addition like this would go a long way to ease admin burdens.
