+* api: add the ability to specify a path prefix for when consul is behind a reverse proxy or API gateway [[GH-12914](https://github.com/hashicorp/consul/issues/12914)]
+* connect: add validation to ensure connect native services have a port or socketpath specified on catalog registration.
+This was the only missing piece to ensure all mesh services are validated for a port (or socketpath) specification on catalog registration. [[GH-12881](https://github.com/hashicorp/consul/issues/12881)]
+* Support Vault namespaces in Connect CA by adding RootPKINamespace and

+* acl: Clarify node/service identities must be lowercase [[GH-12807](https://github.com/hashicorp/consul/issues/12807)]
+* connect: Added a `max_inbound_connections` setting to service-defaults for limiting the number of concurrent inbound connections to each service instance. [[GH-13143](https://github.com/hashicorp/consul/issues/13143)]
+* dns: Added support for specifying admin partition in node lookups. [[GH-13421](https://github.com/hashicorp/consul/issues/13421)]

+* telemetry: Added a `consul.server.isLeader` metric to track if a server is a leader or not. [[GH-13304](https://github.com/hashicorp/consul/issues/13304)]
+* ui: removed external dependencies for serving UI assets in favor of Go's native embed capabilities [[GH-10996](https://github.com/hashicorp/consul/issues/10996)]

+* proxycfg: Fixed a minor bug that would cause configuring a terminating gateway to watch too many service resolvers and waste resources doing filtering. [[GH-13012](https://github.com/hashicorp/consul/issues/13012)]
+* raft: upgrade to v1.3.8 which fixes a bug where non cluster member can still be able to participate in an election. [[GH-12844](https://github.com/hashicorp/consul/issues/12844)]
+* serf: upgrade serf to v0.9.8 which fixes a bug that crashes Consul when serf keyrings are listed [[GH-13062](https://github.com/hashicorp/consul/issues/13062)]
