Hello @Paulius11, thank you for your contribution. I'm sharing a guide that I think will be useful for you during the migration: https://github.com/OCA/maintainer-tools/wiki/Migration-to-version-17.0.
The guide explains the changes introduced in this version, provides a brief explanation on how to clone the repo and bring in the changes affecting the addon from the source version, and also describes how the commit structure should be.
