There have been discussions within Cotonti Team about our near future and eventually we decided that:

  • In one of the following releases Cotonti will ship with new admin and frontend themes, both based on Twitter Bootstrap 3. This site will receive a new look too. Work on all 3 themes is already in progress.
  • We are going to add some Wiki functionality to Documentation section on this site, so it will be easier to participate for everybody who wants to.
  • Multilingual support will be improved both in Cotonti and on this site.
  • Siena development will continue the path of small improvements. We don't plan any major or backwards incompatible changes in 0.9 and 1.x, so you can safely base your extensions and themes on it.

Our @Cotonti twitter is back to life with recent news and updates. You can also follow us on Google+.

Bonus: if you're using SublimeText 2 or 3 for your Cotonti development, try our Sublime Cotonti package (also available as Cotonti within Sublime Package Control). It contains common code snippets and auto-completion for the most of core functions.
