Yesterday samba 4 alpha 9 got released. This requires >=tdb-1.1.7, but on http://samba.org/ftp/tdb/ I don't see it. Since I (and many distros) prefer using system wide libraries instead of bundles ones, a separate release would be appreciated.
tdb-1.2.0 tarballs tagged and cut.
They are available from the usual tdb release directory.
