A preliminary variant of the Sourceforge news retriever is implemented. It just looks for project news/blog entries with a x.y* version number in the title. Then copies the text verbatim as changelog.
This might be troublesome when those repost a lengthy project intro text, and not just a news summary. But that's an issue for standard changelogs as well; so let's just test this for a while..
(Previous ToDo List)
Currently investigating whether project News make a suitable source.
Here a simple check for contained version numbers d+.d+ in headlines might suffice.
Possible later refinements for aggregating a release summary:
Bullet-lists (like for Github) would indicate a summarized change entry.
And ordinary text paragraphs would be reused if /changed fixed added/ hints at actual changes.
