+Release Notes
+-------------
+
+2006-07-24  v0.9.1
+
+Major changes between Mercurial 0.9 and 0.9.1:
+
+ New features:
+ - You can now configure your 'hgweb' server to let remote users
+   'push' changes over http.
+ - You can now 'import' a patch in a mail message by saving the mail
+   message, and importing it.  This works for patches sent either
+   inline or as attachments.
+ - The 'diff' command now accepts '-rA:B' syntax as a synonym for
+   '-r A -r B', and adds '-b' and '-B' options.
+
+ New contributions and extensions:
+ - The 'acl' extension lets you lock down parts of a repository
+   against incoming changes
+ - The 'extdiff' extension lets you run your favourite graphical
+   change viewer
+ - Comprehensive integration with the 'vim' editor
+ - A restricted shell for 'ssh'-hosted repositories
+ - An importer for 'darcs' repositories
+
+ New hooks added:
+ - 'preupdate' is run before an update or merge in the working
+   directory.
+ - 'update' is run after an update or merge in the working
+   directory.
+
+ Behaviour changes:
+ - NOTE: Mercurial as installed by the Windows binary
+   installer no longer performs automatic line-ending conversion for
+   Unix/Linux compatibility.  To re-enable this feature, edit your
+   'mercurial.ini' file after you upgrade.
+ - The Windows binary installer now automatically adds 'hg' to your
+   '%PATH%'.
+ - The 'backout' command now runs an editor by default, to let you
+   modify the commit message for a backed-out changeset.
+ - An earlier problem with parsing of tags has been fixed.
+   This makes tag parsing slower but more reliable.
+
+ Memory usage and performance improvements:
+ - The 'remove' command has been rewritten to be hundreds of times
+   faster in large repositories.
+ - It is now possible to 'clone' a repository very quickly over a
+   LAN, if the server is configured to allow it.  See the new 'server'
+   section in the 'hgrc' documentation.
+
+ Other changes of note:
+ - Mercurial will now print help for an extension if you type 'hg
+   help EXT_NAME'.
+ - The usual array of bug fixes and documentation improvements.
+ - The integrated web server is now more WSGI-compliant.
+ - Work has begun to solidify Mercurial's API for use by third-party
+   packages.

 Release Notes
 -------------
 
+2006-07-24  v0.9.1
+
+Major changes between Mercurial 0.9 and 0.9.1:
+
+ New features:
+ - You can now configure your 'hgweb' server to let remote users
+   'push' changes over http.
+ - You can now 'import' a patch in a mail message by saving the mail
+   message, and importing it.  This works for patches sent either
+   inline or as attachments.
+ - The 'diff' command now accepts '-rA:B' syntax as a synonym for
+   '-r A -r B', and adds '-b' and '-B' options.
+
+ New contributions and extensions:
+ - The 'acl' extension lets you lock down parts of a repository
+   against incoming changes
+ - The 'extdiff' extension lets you run your favourite graphical
+   change viewer
+ - Comprehensive integration with the 'vim' editor
+ - A restricted shell for 'ssh'-hosted repositories
+ - An importer for 'darcs' repositories
+
+ New hooks added:
+ - 'preupdate' is run before an update or merge in the working
+   directory.
+ - 'update' is run after an update or merge in the working
+   directory.
+
+ Behaviour changes:
+ - NOTE: Mercurial as installed by the Windows binary
+   installer no longer performs automatic line-ending conversion for
+   Unix/Linux compatibility.  To re-enable this feature, edit your
+   'mercurial.ini' file after you upgrade.
+ - The Windows binary installer now automatically adds 'hg' to your
+   '%PATH%'.
+ - The 'backout' command now runs an editor by default, to let you
+   modify the commit message for a backed-out changeset.
+ - An earlier problem with parsing of tags has been fixed.
+   This makes tag parsing slower but more reliable.
+
+ Memory usage and performance improvements:
+ - The 'remove' command has been rewritten to be hundreds of times
+   faster in large repositories.
+ - It is now possible to 'clone' a repository very quickly over a
+   LAN, if the server is configured to allow it.  See the new 'server'
+   section in the 'hgrc' documentation.
+
+ Other changes of note:
+ - Mercurial will now print help for an extension if you type 'hg
+   help EXT_NAME'.
+ - The usual array of bug fixes and documentation improvements.
+ - The integrated web server is now more WSGI-compliant.
+ - Work has begun to solidify Mercurial's API for use by third-party
+   packages.

+# To avoid sending patches prematurely, it is a good idea to first run
+# the "email" command with the "-n" option (test only).  You will be
+# prompted for an email recipient address, a subject an an introductory
+# message describing the patches of your patchbomb.  Then when all is
+# done, your pager will be fired up once for each patchbomb message, so
+# you can verify everything is alright.
+#
+# The "-m" (mbox) option is also very useful.  Instead of previewing
+# each patchbomb message in a pager or sending the messages directly,
+# it will create a UNIX mailbox file with the patch emails.  This
+# mailbox file can be previewed with any mail user agent which supports
+# UNIX mbox files, i.e. with mutt:
+#
+#   % mutt -R -f mbox
+#
+# When you are previewing the patchbomb messages, you can use `formail'
+# (a utility that is commonly installed as part of the procmail package),
+# to send each message out:
+#
+#  % formail -s sendmail -bm -t < mbox

+mq extension - patch management and development
+
+This extension lets you work with a stack of patches in a Mercurial
+repository.  It manages two stacks of patches - all known patches, and
+applied patches (subset of known patches).
+
+Known patches are represented as patch files in the .hg/patches
+directory.  Applied patches are both patch files and changesets.
+
+Common tasks (use "hg help command" for more details):
+
+prepare repository to work with patches   qinit
+create new patch                          qnew
+import existing patch                     qimport
+
+print patch series                        qseries
+print applied patches                     qapplied
+print name of top applied patch           qtop
+
+add known patch to applied stack          qpush
+remove patch from applied stack           qpop
+refresh contents of top applied patch     qrefresh
+
+list of commands (use "hg help -v mq" to show aliases and global options):
+
+ qapplied     print the patches already applied
+ qclone       clone main and patch repository at same time
+ qcommit      commit changes in the queue repository
+ qdelete      remove patches from queue
+ qdiff        diff of the current patch
+ qfold        fold the named patches into the current patch
+ qguard       set or print guards for a patch
+ qheader      Print the header of the topmost or specified patch
+ qimport      import a patch
+ qinit        init a new queue repository
+ qnew         create a new patch
+ qnext        print the name of the next patch
+ qpop         pop the current patch off the stack
+ qprev        print the name of the previous patch
+ qpush        push the next patch onto the stack
+ qrefresh     update the current patch
+ qrename      rename a patch
+ qrestore     restore the queue state saved by a rev
+ qsave        save current queue state
+ qselect      set or print guarded patches to push
+ qseries      print the entire series file
+ qtop         print the name of the current patch
+ qunapplied   print the patches not yet applied
+ strip        strip a revision and all later revs on the same branch
