Version 2.9.9 for N900 is now available in here. Debian package creation won't work in my Qt Creator anymore so there's no .deb file but only binary.

Installation instructions:
1. Extract "Mapsi" from rar package to e.g. /home/user (not in MyDocs or its subfolders) (If you have older Mapsi version installed I think you can also overwrite Mapsi file in /opt/usr/bin/)
2. Make it executable with "chmod +x Mapsi" (you'll need to be root so run "sudo gainroot" first)
3. Copy wms_settings.ini to /home/user/MyDocs/.mapsi (see this post for wms_settings.ini file)
4. Run with "./Mapsi"

Changes from the last version are mostly bug fixes (e.g. landmark naming should work now) and performance improvements.

Edit: Dependencies are qtquickcompat, libqtm-11-location, libqtm-11-systeminfo, libqt4-declarative, libqt4-script, libqt4-svg, libqt4-sql, libqt4-xmlpatterns, libqt4-opengl, libqt4-gui, libqt4-network, libqt4-dbus, libqt4-xml, libqt4-core and libc6. You'll need to install those to get Mapsi working (if you have older version of Mapsi installed you should already have those).
