+Add several fixes and improvements in Ekka and Mria.
+
+Ekka:
+  - improve cluster discovery log messages to consistently describe actual events
+    [Ekka PR](https://github.com/emqx/ekka/pull/204)
+  - remove deprecated cluster auto-clean configuration parameter (it has been moved to Mria)
+    [Ekka PR](https://github.com/emqx/ekka/pull/203)
+
+Mria:
+  - ping only running replicant nodes. Previously, `mria_lb` was trying to ping both stopped and running
+    replicant nodes, which might result in timeout errors.
+    [Mria PR](https://github.com/emqx/mria/pull/146)
+  - use `null_copies` storage when copying `$mria_rlog_sync` table.
+    This fix has no effect on EMQX for now, as `$mria_rlog_sync` is only used in `mria:sync_transaction/2,3,4`,
+    which is not utilized by EMQX.
+    [Mria PR](https://github.com/emqx/mria/pull/144)
