+
+- push: improved detection of obsoleted remote branch (issue4354),
+- drop compatibility for Mercurial < 3.8,
+- removed old (unpackaged) pushexperiment extension,
+- move all extensions in the official 'hgext3rd' namespace package,
+- add the "topic" experimental extensions. See the README.topic file for details
+- officially ship 'evolve.serveronly' extensions. That extensions contains
+  only the part related to exchange and is intended to be used by server.
+
+  Using the extension will enable evolution, use 'experimental.evolution=!'

+  option is no longer supported.
+
+- a new prototype of obsmarker discovery is available. The prototype is still
+  at early stage and not recommended for production.
+  Examples of current limitations:
+
+  - write access to the repo is highly recommanded for all operation,
+  - large memory footprint,
+  - initial caching is slow,
+  - unusable on large repo (because of various issue pointed earlier),
+  - likely to constains various bugs.
+
+  It can be tested by setting `experimental.obshashrange=1` on both client and
+  server. It is recommanded to get in touch with the evolve maintainer if you
+  decide to test it.
+
+- the 'debugrecordpruneparents' have been moved into the 'evolve.legacy'
+  separate extension. enable that extentions if you need to convert/update
+  markers in an old repository.

-6.0.0 -- 2017-03-31

-- removed old (unpackaged) pushexperiment extension,
-- move all extensions in the official 'hgext3rd' namespace package,
-- add the "topic" experimental extensions. See the README.topic file for details
-- officially ship 'evolve.serveronly' extensions. That extensions contains
-  only the part related to exchange and is intended to be used by server.
-
-  Using the extension will enable evolution, use 'experimental.evolution=!'
-  to disable obsmarkers echange.  The old '__temporary__.advertiseobsolete'
-  option is no longer supported.
-
-- a new prototype of obsmarker discovery is available. The prototype is still
-  at early stage and not recommended for production.
-  Examples of current limitations:
-
-  - write access to the repo is highly recommanded for all operation,
-  - large memory footprint,
-  - initial caching is slow,
-  - unusable on large repo (because of various issue pointed earlier),
-  - likely to constains various bugs.
-
-  It can be tested by setting `experimental.obshashrange=1` on both client and
-  server. It is recommanded to get in touch with the evolve maintainer if you
-  decide to test it.
-
-- the 'debugrecordpruneparents' have been moved into the 'evolve.legacy'
-  separate extension. enable that extentions if you need to convert/update
-  markers in an old repository.

-Topic Extension
-================
-
-This packages also provides the ``topic`` experiment in an independent
-extension. It implements a new experimental concept to provide lightweight
-feature branches for the mutable parts of the history. The experiments is still
-at an early stage and have significant usability and performance issues when
-enabled.
-
-How to Install
-==============
-
-The ``topic`` extension is included into the ``evolve` package, so the same instruction apply.
-
-Using Pip
----------
-
-You can install the latest version using pip::
-
-    $ pip install --user hg-evolve
-
-Then just enable it in you hgrc::
-
-    $ hg config --edit # adds the two line below:
-    [extensions]
-    topic =
-
-From Source
------------
-
-To install a local version from source::
-
-    $ hg clone https://www.mercurial-scm.org/repo/evolve/
-    $ cd evolve
-    $ make install-home
-
-Enable
-------
-
-The topic extensions is included in the evolve package. See the install instruction for evolve.
-
-Then enable it in you configuration::
-
-    $ hg config --edit # adds the two line below:

+Topic Extension
+================
+
+This packages also provides the ``topic`` experiment in an independent
+extension. It implements a new experimental concept to provide lightweight
+feature branches for the mutable parts of the history. The experiments is still
+at an early stage and have significant usability and performance issues when
+enabled.
+
+How to Install
+==============
+
+The ``topic`` extension is included into the ``evolve` package, so the same instruction apply.
+
+Using Pip
+---------
+
+You can install the latest version using pip::
+
+    $ pip install --user hg-evolve
+
+Then just enable it in you hgrc::
+
+    $ hg config --edit # adds the two line below:
+    [extensions]
+    topic =
+
+From Source
+-----------
+
+To install a local version from source::
+
+    $ hg clone https://www.mercurial-scm.org/repo/evolve/
+    $ cd evolve
+    $ make install-home
+
+Enable
+------
+
+The topic extensions is included in the evolve package. See the install instruction for evolve.
+
+Then enable it in you configuration::
+
+    $ hg config --edit # adds the two line below:
+    [extensions]
+    topic =

+Documentation

+* See 'hg help -e topic' for a generic help.
+* See 'hg help topics' and 'hg help stack' for help on specific commands.
+* See the 'tests/test-topic-tutorial.t' file for a quick tutorial.

 Be aware that this extension is still an experiment, commands and other features
