 Changelog
 =========
 
+5.2.0 --
+
+- evolve: gain a --rev option to control what revisions to evolve (issue4391)
+- evolve: revision are processed in the order they stack on destination
+- evolve: properly skip unstable revision with non-evolved unstable parent
+- evolve: gain --unstable --divergent --bumped flag to select the trouble
+- evolve: issue more useful error message and hint when evolve has nothing to
+          do as invocated.
+- evolve: bare `hg evolve` commands now abort when multiple changesets could be
+          a target.
+- evolve: `hg evolve --all` only evolve changeset that will end up as
+          descendant of the current working copy. The old behavior of `--all`
+          in now in `--all --any`.
+
 5.1.5 -- 2015-06-23

+Obsolescence markers make it possible to mark changesets that have been
+deleted or superset in a new version of the changeset.
+
+Unlike the previous way of handling such changes, by stripping the old
+changesets from the repository, obsolescence markers can be propagated
+between repositories. This allows for a safe and simple way of exchanging
+mutable history and altering it after the fact. Changeset phases are
+respected, such that only draft and secret changesets can be altered (see
+:hg:`hg phases` for details).
+
+Obsolescence is tracked using "obsolete markers", a piece of metadata
+tracking which changesets have been made obsolete, potential successors for
+a given changeset, the moment the changeset was marked as obsolete, and the
+user who performed the rewriting operation. The markers are stored
+separately from standard changeset data can be exchanged without any of the
+precursor changesets, preventing unnecessary exchange of obsolescence data.
+
+The complete set of obsolescence markers describes a history of changeset
+modifications that is orthogonal to the repository history of file
+modifications. This changeset history allows for detection and automatic
+resolution of edge cases arising from multiple users rewriting the same part
+of history concurrently.
+
+Current feature status
+======================
+
+This feature is still in development.  If you see this help, you have enable an
+extension that turned this feature on.
+
+Obsolescence markers will be exchanged between repositories that explicitly
+assert support for the obsolescence feature (this can currently only be done
+via an extension).""".strip()

+  Safely Rewriting History
+  """"""""""""""""""""""""
+  
+      Obsolescence markers make it possible to mark changesets that have been
+      deleted or superset in a new version of the changeset.
+  
+      Unlike the previous way of handling such changes, by stripping the old
+      changesets from the repository, obsolescence markers can be propagated
+      between repositories. This allows for a safe and simple way of exchanging
+      mutable history and altering it after the fact. Changeset phases are
+      respected, such that only draft and secret changesets can be altered (see
+      "hg hg phases" for details).
+  
+      Obsolescence is tracked using "obsolete markers", a piece of metadata
+      tracking which changesets have been made obsolete, potential successors
+      for a given changeset, the moment the changeset was marked as obsolete,
+      and the user who performed the rewriting operation. The markers are stored
+      separately from standard changeset data can be exchanged without any of
+      the precursor changesets, preventing unnecessary exchange of obsolescence
+      data.
+  
+      The complete set of obsolescence markers describes a history of changeset
+      modifications that is orthogonal to the repository history of file
+      modifications. This changeset history allows for detection and automatic
+      resolution of edge cases arising from multiple users rewriting the same
+      part of history concurrently.
+  
+      Current feature status
+      ======================
+  
+      This feature is still in development.  If you see this help, you have
+      enable an extension that turned this feature on.
+  
+      Obsolescence markers will be exchanged between repositories that
+      explicitly assert support for the obsolescence feature (this can currently
+      only be done via an extension).
