Mutable History For Mercurial

Extends Mercurial feature related to Changeset Evolution

This extension provides several commands to mutate history and deal with issues it may raise.

It also:

  • enables the "Changeset Obsolescence" feature of mercurial,
  • alters core commands and extensions that rewrite history to use this feature,
  • improves some aspect of the early implementation in 2.3

These extensions are experimental and are not meant for production.

You can quicky enable it by adding the line below to the extensions section of you hgrc:


But it's recommended to look at the doc in the first place.

See doc/ directory for details.

Online version of the doc is available:



The simplest way to contribute is to issue a pull request on bitbucket.

However, some cutting edge change may be found in a mutable repository hosted by logilab before they are published.


Make sure to check lastest draft changeset before submitting new changeset.
