- 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.
