"UNSTABLE Gramps 4.0.0 Alpha1 release. This is a technology preview to allow plugin writers and packagers-installer writers to update their plugins and scripts. This release is not production ready, so use for testing!" It is recommended to use Gramps 4.0.0 with python 3.2 so as to be ready for the future (python 2.7 works though). The dependencies for Gramps 4.0.0 are _completely_ different than 3.4 due to the switch to GObject introspection, and the removal of autotools. So only install 4.0.0 if you are certain you can obtain the dependencies, see README and INSTALL. For linux, in Ubuntu 12.10 you can install 4.0.0, but you will need to compile and install osmgpsmap manually to have the maps working (see http://www.gramps-project.org/wiki/index.php?title=GEPS_029:_GTK3-GObject_introspection_Conversion#OsmGpsMap_for_Geography ) Major enhancements in Gramps 4.0.0: * GEP 8: code reorganization: http://www.gramps-project.org/wiki/index.php?title=GEPS_008:_File_Organization * GEP 26: Replace make: http://www.gramps-project.org/wiki/index.php?title=GEPS_026:_Replace_%27make%27_for_Gramps_build * GEP 29: Gtk 3 :http://www.gramps-project.org/wiki/index.php?title=GEPS_029:_GTK3-GObject_introspection_Conversion * GEP 31: Python 3 support: http://www.gramps-project.org/wiki/index.php?title=GEPS_031:_Python_3_support More info in the manual http://www.gramps-project.org/wiki/index.php?title=Gramps_4.0_Wiki_Manual_-_What%27s_new%3F Everybody is invited to update the manual to make it current!
