Notmuch 0.10 (2011-xx-xx)
=========================
+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
-------------------------
search/show/tag. The output file argument of dump is deprecated in
favour of using stdout.
+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.
+
+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
+
+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.
