Hi @jescalada! Thanks for your contribution to GitProxy.

I notice a couple of things that would help with reviewing this PR:

Missing description: Could you please add a description explaining what this PR does? Even a brief explanation of what "retest feature on 1.2.0" means would be helpful for reviewers to understand the changes.

Missing issue link: According to our contributing guidelines, PRs should be linked to an existing issue using keywords like "Fixes #N", "Closes #N", or "Resolves #N". If there isn't an existing issue for this work, please consider creating one first, or let us know if this addresses an existing issue that we can link to.

Thanks for helping make GitProxy better! 🚀
