+# What's new in Gerrit Multi-Site
+
+Gerrit Multi-Site plugin is reaching its 4th anniversary,
+after its inception back in February 2019.
+
+Over the years, it has gone through
+[different maturity stages](https://gerrit.googlesource.com/plugins/multi-site/+/refs/heads/master/DESIGN.md#the-road-to-multi_site)
+and has gone recently through major improvements, thanks also
+the advances in provided by the
+[pull-replication plugin](https://gerrit.googlesource.com/plugins/pull-replication/+/refs/heads/master/src/main/resources/Documentation/about.md).
+
+Luca gives an overview of the recent advances in the
+Gerrit multi-site architecutre, including:
+
+- Reduction of the replication lag latency with synchronous
+  pull-replication
+- Simplification of the multi-site setup, based on pure
+  Git/HTTPS connections
+- Managing sites downtimes and catch-up using an event
+  message broker
+- Putting replicas in the Gerrit multi-site picture
+- Managing multi-site migrations
+
+GerritHub.io has also gone through all the evolution of the
+Gerrit multi-site maturity stages and experienced unprecedented
+reliability, heading towards a 99.999% uptime.
