There is a thread on this:viewtopic.php?f=35&t=8470
But in summary:
- Aiming to make it the most stable platform out there
- Multiple exporters (HTML5 first, then editor will support any number of other specialised exporters)
- XML data format, this will make it a lot easier for you and groups of people to manage their data/backups etc
- Project folder structure
- Improved interface, a lot easier to use, a lot better looking and a lot more functional
And lots more planned. We really are aiming to make it the best 2d games making tool out there.
With Construct 2 as well, we are going to be focussing a lot more on the community as well, with a great new website on the way.
