+Xapian (and notmuch) will continue using the 1.2 era "chert" backend for\r
+existing databases. This is what I've been doing for some time now,\r
+using a chert backend with xapian 1.3. To force an upgrade to glass\r
+would require dump, move .notmuch out of the way, notmuch new, and\r
+restore. That should also work, since the test suite uses the glass\r
+backend, but I'm not sure if it's worth the trouble at this point. I\r
+know that the Xapian team is still doing performance tuning on the glass\r
+backend.\r
+\r
+all the best\r
