Make sure you have zest.releaser with qgispluginreleaser installed. The qgispluginreleaser ensures the metadata.txt, which is used by the qgis plugin manager, is also updated to the new version. To make a new release enter the following commands and follow their steps:

$ cd /path/to/the/plugin
$ fullrelease

This creates a new release and tag on github. Additionally, a zip file threedi_models_and_simulations.<version>.zip is created. Upload this zip-file to https://artifacts.lizard.net/ via the upload-artifact.sh script. You'll need to set $ARTIFACTS_KEY environment variable. Get the key from https://artifacts.lizard.net/admin/ Afterwards run it like this:

$ make zip
$ bash upload-artifact.sh threedi_api_qgis_client_<version>.zip

On Linux, local development happens with docker to make sure we're working in a nicely isolated environment. To start the development environment, run the following commands:

$ docker compose build
$ xhost +localhost
$ docker compose up

and:

$ docker compose run --rm qgis make test

On Mac, you might need to install xquartz, adjust the DISPLAY env variable in the docker-compose.yml to host.docker.internal:0 and remove the //tmp/x-something mount from volumes.
