### Problem to solve
It is not possible to find out the exact version/release/tag which has the fix gone into product via MR from UI. Workaround is to clone the repo scan with `git tag --contains …mr…commit…id… | sort --version-sort | head` for the merge commit and find the release details. There is milestone mentioned in MRs, but some will have incorrect milestone details or expired milestones and usually only list `X.y` version without `.z`/patch.
### Proposal
Either give the tag details in MR page or provide a tool which can query for release details using MR provided
