On mobile right now so can't investigate properly, but if you visit https://github.com/OfflineIMAP/offlineimap/releases/latest it shows the latest release as May 2014. Think we had a similar issue awhile ago, not sure if it got solved though.
This is the relevant post: https://github.com/badges/shields/issues/1355#issuecomment-350102951
On your repo, v6.5.6 (25 May 2014) is a _release_, whereas v7.1.5 (13 Jan 2018) is a _tag_ but confusingly GitHub uses these terms slightly differently in the web front-end and the API which sometimes causes confusion.
Let us know if you have other questions!
Is there any way to get this latest release date information from the github version tags? For a repo which has no github "release" objects. Or for a repo where the latest "release" object is many, many "tags" behind. For example, this repo: https://github.com/OfflineIMAP/offlineimap/releases/latest
Yes, you can use /github/tag:
https://img.shields.io/github/tag/OfflineIMAP/offlineimap.svg
However it's not 100% reliable. See #875.
