Sterna now shows an offline banner as soon as you lose connectivity, not only after a failed refresh. When you send, the notice reads "Sending…" instead of prematurely saying the message was already sent. You can set a default identity per account, which is pre-selected when you compose. A draft can be saved without a recipient, and a draft kept in the Trash is now marked as a draft. The account's identities screen was reworked: identities your server provides are shown separately from ones you add, editing an identity's name or signature now saves correctly, and duplicate identities are cleaned up. The reply and forward bar no longer flickers when system animations are turned off, and several labels were clarified (the OpenPGP settings and the mark-as-read option).
