Brewblox release 2024/02/23

firmware release date: 2024/02/23

For this release, we’ve focused on fixing bugs and updating dependencies.

The website has a new look and feel, and now supports both light and dark mode.
We also reorganized the pages slightly to make the sidebar index more intuitive.

For our Python services, we decided to switch from Aiohttp to FastAPI.
This simplified the code greatly, to the point where the shared brewblox-service dependency is no longer useful. We updated brewblox-boilerplate accordingly.

This change to how services are built also changed how they accept configuration options.
Before, services were configured using the command section in docker-compose.yml.
Now, they use the environment section.
To provide backwards compatibility, the service command is still parsed, and known options are converted to environment variables.

Supported environment options for Python services can be found under


  • (feature) Brewblox services now use environment variables for configuration. command is still parsed for backwards compatibility.
  • (improve) The Spark service will now automatically detect its name. The --name / BREWBLOX_SPARK_NAME argument is optional.
  • (improve) The Docker Compose bridge network interface now has a name (default: br-brewblox).
  • (improve) The CA cert menu now also shows instructions for (some versions of) Android.
