+
+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.
