The only exceptional requirement file is `devel.txt`, which aggregated all the needed requirements for development.
## CI/CD upper bounds
For Ci stability, we have set for all package versions upper bounds (the latest version), so with any sudden release, we won't put our development on fire.
The continues updated of these upper bounds are managed by dependabot.
Note that these upper bounds are lifters when installing a package from the source or as a package.
If you want to preserve/enforce restrictions on the latest compatible version, add "strict" as an in-line comment.
