6.1.0 – 2017-05-03

• improve message about obsolete working copy parent,

• improve message issued when accessing hidden nodes (4.2 only),

• introduce a new caches to reduce the impact of evolution on read-only commands,

• add a ‘experimental.auto-publish’ config. See hg help -e evolve for details.

• fix the propagation of some some cache invalidation,

6.0.1 – 2017-04-20

• template: adapt to change in 4.2,

• fix ‘debugrecordpruneparents’ (outdated API usage)

• checkheads: give priority to updated 4.2 code,

• serveronly: fix repository initialization.

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.
