Qt4 is dead and going away. This package has ongoing but non-trivial efforts to port to Qml, see URL, and could use n helping hands upstream. We don't have to rush removal as long as there are signs of progress and other packages blocking qt4-removal, but ultimately <=0.9.23 will have to go together with Qt4.

Just FYI. unc0rr made this interim branch: https://hg.hedgewars.org/hedgewars/log?rev=branch(qt5transition) It makes use of the fact that while qt5 removed the FileEngine he was using for physfs, it is still available privately, at least for now. https://hg.hedgewars.org/hedgewars/diff/12897/QTfrontend/util/FileEngine.h In testing, it seems fine, apart from qt5 messing up some styling, an old problem with Qt that setting app.setStyle("fusion") in main.cpp seems to fix. Apart from that, I didn't run into any issues. We can use this approach for now, since the qml frontend branch will require a lot more work.
