+Add "notmuch search" --offset and --limit options
+
+  The search command now takes options --offset=[-]N and --limit=N to limit
+  the number of results shown.
+
+Add "notmuch count --output" option
+
+  The count command is now capable of counting threads in addition to
+  messages. This is selected using the new --output=(threads|messages) option.
+
+Performance
+-----------
+
+Emacs now constructs large search buffers more efficiently
+
+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
+
+New collection of add-on tools
+------------------------------
+
+The source directory "contrib" contains tools built on notmuch.  These
+tools are not part of notmuch, and you should check their individual
+licenses.  Feel free to report problems with them to the notmuch
+mailing list.

+nmbug - share tags with a given prefix
+
+   nmbug helps maintain a git repo containing all tags with a given
+   prefix (by default "notmuch::"). Tags can be shared by commiting
+   them to git in one location and restoring in another.
