Release 5.3.12 is now staged for final testing.
Version nomenclature has changed. The last two digits (aka 3.12 for 5.3.12) correspond to the gtk version the code has been prepared for. Thus, version 5.3.12 will work best with gtk+-3.12.x.
Compilation with gtk+-2.x is still available, but many new features (like the pathbar) will not be available.
Final release should come in the following days if all goes well.
