 Changelog
 =========

-10.3.3 - in progress
+10.4.0 - in progress
 --------------------

+  * evolve: use a more stable criteria for picking p1 when solving
+    content-divergence (most recent evolution will be used)
+  * evolve: drop the deprecated --unstable, --divergent and --bumped flags,
+    they were replaced by --orphan, --content-divergent and --phase-divergent
+    respectively a long time ago
+  * evolve: remove experimental.obshashrange.lru-size docs, that config option
+    didn't do anything for a long time
+  * evolve: use precheck function from Mercurial 5.9+ when available, mostly
+    affects error messages and exit codes
+
+  * next: add an --abort flag
+
+  * evolve, topic, pullbundle: drop compatibility with Mercurial 4.6
+
+topic (0.23.0)
+
+  * topic: don't cache .topic() of memctx instances, as that could produce
+    KeyError: b'topic' during some rewrite operations (issue6500)
+  * topic: drop old code for working with amends on ancient hg versions (~3.6)
+
+10.3.3 -- 2021-08-13
+--------------------
+
+  * evolve: compatibility with Mercurial 5.9
   * fold: make sure to save commit messages in last-message.txt, also affects
     metaedit (issue6549)
+  * touch/fold/metaedit/rewind: no longer lose changes from merge commits
+    (issue6416). As a consequence (for technical reasons), when run with
+    Mercurial 5.5 and earlier, these commands now require there to be no
+    unresolved conflicts.

 topic (0.22.3)

   * topic: correctly update from public commits with a (now hidden) topic
     when hg update is called without any revision (issue6553)
+  * topic: fix the help text to show how to disable publishing

-10.3.2 - 2021-05-28
+
+10.3.2 -- 2021-05-28
 --------------------

   * next: remove duplicated targets when updating from an unstable changeset
   * evolve: use "served" repo filter to guess what the server will publish
-  * touch/fold/metaedit/rewind: no longer lose changes from merge commits
-    (issue6416). As a consequence (for technical reasons), when run with
-    Mercurial 5.5 and earlier, these commands now require there to be no
-    unresolved conflicts.

+=====================================
+Testing content-divergence resolution
+=====================================
+
+Independent rewrites of same changeset can lead to content-divergence. In most
+common cases, it can occur when multiple users rewrite the same changeset
+independently and push it.
+
+This test aims to check that the resolution of content-divergent changesets is
+independent of the user resolving the divergence. In other words, the two users
+resolving the same divergence should end up with the same result.
