-topic (0.22.4)
+  * 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)

+=====================================
+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.
