 Mercurial. They are the "mercurial-x.y" branches. They are used to apply
 expected test change only, no code change should happen there.

-
-6.0.0 -- 2017-03-31
--------------------
-
-- 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=!'
-  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.
