In the web-app when browsing a release, the release message can be the realease name and provide very little information, because the only message kept is the one stored in git.
See: https://archive.softwareheritage.org/browse/origin/https://github.com/RaRe-Technologies/gensim/releases/
On Github the release page has a detailed description that should be kept with the release.
Example:
https://github.com/RaRe-Technologies/gensim/releases/tag/3.4.0
"body" element in :
https://api.github.com/repos/RaRe-Technologies/gensim/releases/tags/3.4.0
Two options:
1. have it directly in the release object
2. create a release_metadata table for all the stuff found with the release including assets or links to assets
