Every once in awhile I've found an idea for a service which would for one reason or another need to know what releases of MediaWiki exist and which ones are obsolete.
As far as I know, we don't have any sort of API or machine readable metadata at all declaring this information for services to use.
I'd like to see a change to the release workflow made that would support this use case. Some time ago I thought we should do this with an api, but now I think we can probably cover this by publishing a simple json file at either one of these urls: https://www.mediawiki.org/releases.json https://releases.wikimedia.org/mediawiki/releases.json
The file will need to be updated every time a new release is made or an old one becomes obsolete.
What does everyone and the release managers think?
