Go to the Git Actions panel, and run a Release new version
manual workflow, specifying the name of the new version (which will be used, among other things, for the tab and the suffix of the user-agent).
The Release workflow will:
- Insert the version in the Dockerfile and README.md files, create a new commit and tag it
- Build the Docker file and push it to DockerHub
- Create a new GitHub Release based on the tag created previously
It's really that simple :-)
