Is there any chance that release notes could be included in the actual release on github, and/or in a CHANGELOG.md in the repo, in the future? Github issues are an unintuitive place to look for release notes.

@briancolecoinmetrics thanks for the suggestion. I think we could introduce the CHANGELOG.md, I'll entertain the idea of doing this. Btw, we usually have some log here as well https://github.com/mimblewimble/grin/releases/tag/v5.1.0 but it's not really as structure as the one above.

[briancolecoinmetrics]

Sweet, thank you:)

Yeah, I actually hesitated to ask because the release page has something already, but this is much more readable.
