+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.
+
+New emacs UI features
+---------------------
+
+Add tab-completion for notmuch-search and notmuch-search-filter
+
+ These functions now support completion tags for query parts
+ starting with "tag:".
+
+Turn "id:MSG-ID" links into buttons associated with notmuch searches
+
+ Text of the form "id:MSG-ID" in mails is now a clickable button that
+ opens a notmuch search for the given message id.
+
+Add keybinding ('c I') for stashing Message-ID's without an id: prefix
+
+ Reduces manual labour when stashing them for use outside notmuch.
+
+Do not query on notmuch-search exit
+
+ It is harmless to kill the external notmuch process, so the user
+ is no longer interrogated when they interrupt a search.
+
+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.
