+
+  $ cd $TESTDIR/..
+  $ python3 contrib/relnotes 4.4 --stoprev 4.5
+  New Features
+  ============
+
+  revert --interactive
+  --------------------
+
+  The revert command now accepts the flag --interactive to allow reverting only
+  some of the changes to the specified files.
+
+  Rebase with different destination per source revision
+  -----------------------------------------------------
+
+  Previously, rebase only supports one unique destination. Now "SRC" and
+  "ALLSRC" can be used in rebase destination revset to precisely define
+  destination per each individual source revision.
+
+  For example, the following command could move some orphaned changesets to
+  reasonable new places so they become no longer orphaned:
+
+  hg rebase   -r 'orphan()-obsolete()'   -d 'max((successors(max(roots(ALLSRC) &
+  ::SRC)^)-obsolete())::)'
+
+  Accessing hidden changesets
+  ---------------------------
+
+  Set config option 'experimental.directaccess = True' to access hidden
+  changesets from read only commands.
+
+  githelp extension
+  -----------------
+
+  The "githelp" extension provides the "hg githelp" command. This command
+  attempts to convert a "git" command to its Mercurial equivalent. The extension
+  can be useful to Git users new to Mercurial.
+
+  Other Changes
+  -------------
+
+  * When interactive revert is run against a revision other than the working
+    directory parent, the diff shown is the diff to *apply* to the working
+    directory, rather than the diff to *discard* from the working copy. This is
+    in line with related user experiences with 'git' and appears to be less
+    confusing with 'ui.interface=curses'.
+
+  * Let 'hg rebase' avoid content-divergence by skipping obsolete changesets
+    (and their descendants) when they are present in the rebase set along with
+    one of their successors but none of their successors is in destination.
+
+  * hgweb now displays phases of non-public changesets
+
+  * The "HGPLAINEXCEPT" environment variable can now include "color" to allow
+    automatic output colorization in otherwise automated environments.
+
+  * A new unamend command in uncommit extension which undoes the effect of the
+    amend command by creating a new changeset which was there before amend and
+    moving the changes that were amended to the working directory.
+
+  * A '--abort' flag to merge command to abort the ongoing merge.
+
+  * An experimental flag '--rev' to 'hg branch' which can be used to change
+    branch of changesets.
+
+  Backwards Compatibility Changes
+  ===============================
+
+  * "log --follow-first -rREV", which is deprecated, now follows the first
+    parent of merge revisions from the specified "REV" just like "log --follow
+    -rREV".
+
+  * "log --follow -rREV FILE.." now follows file history across copies and
+    renames.
+
+  Bug Fixes
+  =========
+
+  Issue 5165
+  ----------
+
+  Bookmark, whose name is longer than 255, can again be exchanged again between
+  4.4+ client and servers.
+
+  Performance Improvements
+  ========================
+
+  * bundle2 read I/O throughput significantly increased.
+
+  * Significant memory use reductions when reading from bundle2 bundles.
+
+    On the BSD repository, peak RSS during changegroup application decreased by
+    ~185 MB from ~752 MB to ~567 MB.
+
+  API Changes
+  ===========
+
+  * bundlerepo.bundlerepository.bundle and
+    bundlerepo.bundlerepository.bundlefile are now prefixed with an underscore.
+
+  * Rename bundlerepo.bundlerepository.bundlefilespos to _cgfilespos.
+
+  * dirstate no longer provides a 'dirs()' method.  To test for the existence of
+    a directory in the dirstate, use 'dirstate.hasdir(dirname)'.
+
+  * bundle2 parts are no longer seekable by default.
+
+  * mapping does not contain all template resources. use context.resource() in
+    template functions.
+
+  * "text=False|True" option is dropped from the vfs interface because of Python
+    3 compatibility issue. Use "util.tonativeeol/fromnativeeol()" to convert EOL
+    manually.
+
+  * wireproto.streamres.__init__ no longer accepts a "reader" argument. Use the
+    "gen" argument instead.
+
+  * exchange.getbundlechunks() now returns a 2-tuple instead of just an
+    iterator.
