This release brings a brand new NixOS module and quite a lot of bug fixes and improvements.

• added "Keystroke overlay" setting for recordings and streams, disabled by default
• upgraded asciinema player to 3.16.0

• 4xx client errors are no longer reported to Sentry

NixOS module

This release adds a NixOS module to the flake, exposed as nixosModules.default, configured under services.asciinema.

The module can provision a local PostgreSQL database, generate and persist SECRET_KEY_BASE and the Erlang release cookie, manage upload/cache/runtime directories, pass non-secret runtime configuration through typed environment options, and load secrets from an out-of-store environmentFile.

See NixOS setup docs for quick start and more details.

Upgrading

For regular Docker/container installs, no manual changes are needed other than bumping the container image version number as shown here (https://docs.asciinema.org/manual/server/self-hosting/upgrading/).

If you set TZ in the Docker environment, it should now be honored by the container.
