I’m glad to announce that there are several changes in the software development process of Irrlicht:
Irrlicht now is accessable via CVS. You can grab the latest development version of the engine directly as described in this FAQ entry and it is also possible to browse it via html.
We’ve now got an Irrlicht Engine team, I’ve updated the author page. If you would like to join the team, please take a look at the FAQ entry. Currently, we would be glad to find someone to create and maintain a Mac port, for example (also mentioned in the FAQ entry).
I’ve written some basic Irrlicht coding rules you may want to look at, if you want your additions to be merged with the development code.
