* **Mesh Gateways:** Envoy can now be run as a gateway to route Connect traffic across datacenters using SNI headers, allowing connectivty across platforms and clouds and other complex network topologies. Read more in the [mesh gateway docs](TODO).
* **Intention & CA Replication:** In order to enable connecitivty for services across datacenters, Connect intentions are now replicated and the Connect CA cross-signs from the [primary_datacenter](/docs/agent/options.html#primary_datacenter). This feature was previously part of Consul Enterprise.
IMPROVEMENTS:
* agent: Added tagged addressing to services similar to the already present Node tagged addressing [[GH-5965](https://github.com/hashicorp/consul/pull/5965)]
BUG FIXES:
* autopilot: update to also remove failed nodes from WAN gossip pool [(GH-6028](https://github.com/hashicorp/consul/pull/6028)]
