- Added a message to explain to the user that it needs to build and push images - The Release Name string is now a constant ins source code, later we will be able to change it to (for example) a template call - SHA256 injected label (from docker-compose file content) is a bit long, SHA1 is shorter - We now add compose command line and generation date in the Values file - Code cleanup, refactorisation and enhancements - More documentation in the source code
