The Gramps Developers have released:
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.

Everybody is invited to update the manual to make it current!
