I uploaded it to extras-devel repository (here).

I forgot to mention about v4.0.0 that I know there are quite a few bugs in it but I decided to release it anyway as it still should be pretty stable and working. Most "critical" bugs that I'm aware of are:
- zooming doesn't work very well
- sometimes wrong map tiles are shown or some map tiles are not shown at all
- routes won't work properly (on N900 those don't work at all and on N9 those disappear automatically at some point)
- GPS track drawing probably won't work very well
I'll try to fix these on upcoming versions.

Also from now on it should be trivial to add support for new EPSG projections, so if you want to have support for some EPSG let me know (or if you know some specific WMS server and want to have support for that, give a link to it and I'll see if I can add support for it).
