 Changelog
 =========
 
+10.4.0 - in progress
+--------------------
+
+  * next: add an --abort flag
+  * 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

+
+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.
