Versions, maturity, updates, status

[quassy]

General thoughts, in order of importance of the feature:

• Maturity: The most stable release that is available for the current version (atm Freya), 5 simple levels:
  • stable
  • beta
  • alpha
  • devel
  • wishlist
• Status: Activity of the project, should include both pace and last acivity, three levels. How to measure objectively?
• Versions: Show a list of stable or semi-stable releases together with date
• Updates: Make a post when a new stable version is released (how to keep up?)
