What I'd like to do and why

Add relevant Borg 1.4.2 features to be wrapped in borgmatic:

BORG_MSGPACK_VERSION_CHECK=no to optionally disable the msgpack version check; default is “yes”; use at your own risk, #9109.

This could be a borgmatic configuration option that sets an environment variable when invoking Borg. Lots of existing examples of that.

create: add --files-changed=MODE option (controls how borg detects whether a file has changed while it is being backed up)

This could be a configuration option as well.

Other notes / implementation ideas

No response

Hey! I'm a beginner in open source (Coming over from GSoC) and I'd love to work on this issue. I have implemented the '--files-changed=MODE' flag already, however I'm not sure where to get started on the MSGPACK one.

Welcome! So the existing examples for borgmatic options that set environment variables passed to Borg are here: https://projects.torsion.org/borgmatic-collective/borgmatic/src/branch/main/borgmatic/borg/environment.py#L6 ... And then you can create a new option in schema.yaml. Also check out the source code reference if you haven't already. Let me know if you have any questions.

Note that borgmatic isn't participating in GSoC this year, but you are still more than welcome to submit PRs.

That's fine, I still managed to get valuable experience regarding contributing. I've submitted a PR (correctly I hope?) and I'd like to
know if theres any corrections.
