Build 43 is out, with support for mentioning other users! Just type an '@' to autocomplete another user's name. Other changes:

- Added German translations (thanks Peter!).

- Fixed a bug where expired messages could be redownloaded from relays that don't delete them.

- Fixed a bug where you couldn't view the parent note of a reply when it was displayed at the top of the Thread view.

- Updated support email to support@nos.social
