 Notmuch 0.10 (2011-xx-xx)
+=========================
 
-notmuch dump changes 
---------------------
+New build and testing features
+------------------------------
+
+Emacs tests are now done in dtach. This means that dtach  is now
+needed to run the notmuch test suite, at least until the checking for
+prerequisites is improved.
+
+New command-line features
+-------------------------
+
+Add "notmuch restore --accumulate" option
+
+  The --accumulate switch causes the union of the existing and new tags to be
+  applied, instead of replacing each message's tags as they are read in from
+  the dump file.
+
+Add search terms to  "notmuch dump"
 
-The dump command now takes an optional search term much like notmuch
-search/show/tag. The output file argument of dump is deprecated in
-favour of using stdout.

+
+Optimizations
+-------------
+
+Search avoids opening and parsing message files
+
+  We now store more information in the database so search no longer
+  has to open every message file to get basic headers.  This can
+  improve search speed by as much as 10X, but taking advantage of this
+  requires a database rebuild:
+
+	notmuch dump > notmuch.dump
+	# Backup, then remove notmuch database ($MAIL/.notmuch)
+	notmuch new
+	notmuch restore notmuch.dump
