Improve the RSS feed + discussion about the release annoucement
Currently, we have two kinds of events and three channels:
- releases: via the "events" in main page + RSS feed
- blog posts: via the blog page
@desloges suggested that we could:
- always create a blog post for a release
- fill the RSS with blog posts
By doing this, both releases and blog posts could be visible from the RSS feed. For the main page events, I would suggest to only keep releases (which could be filtered via special yaml parameter), but maybe blog posts could also be announced there.
Finally, we could use a system similar to what is done for blog posts in order to generate a quick description in the RSS.
