Things have been pretty quiet since the 0.7.2 release of Tiled. This was partly due to me working on a rewrite of Tiled, using Qt/C++. I now think this rewrite is complete enough for its first release, though compared to the Java version a lot of features are still missing. You'll find Tiled Qt 0.1.0 on in the Development section of the downloads page.
I'm curious to hear how the Qt version works for you, and am looking forward to hear about everyones favourite missing feature. A new bug tracker has been set up to keep track of your feedback. As always, feel free to email me directly or to write to the tiled-user mailing list.
Finally, I'm looking for additional contributors! Are you familiar with C++ and Qt, or want to learn? Tiled is a relatively small and simple project, with a clean design. Any help is appreciated! :-)
