Does someone has an approximative date for the release of Alchemy version 2 ?
Nothing to announce yet, but we are working on it!
We're waiting excitedly. It will make a lot of difference to our projects, particularly on mobile where performance is a big issue.
I wouldn't recommend using Alchemy on mobile. Alchemy is really great for running C/C++ code in the Flash sandbox, but if you can run code natively (e.g., Air Native Extensions) you should do so.
In my project I use Alchemy when in the browser, and ANE when in Air/Mobile.
