* gateways: service defaults configuration entries can now be used to set default upstream limits for mesh-gateways [[GH-20945](https://github.com/hashicorp/consul/issues/20945)]
* connect: Add ability to disable Auto Host Header Rewrite on Terminating Gateway at the service level [[GH-20802](https://github.com/hashicorp/consul/issues/20802)]
BUG FIXES:
* dns: fix a bug with sameness group queries in DNS where responses did not respect [`DefaultForFailover`](/consul/docs/connect/config-entries/sameness-group#defaultforfailover).
DNS requests against sameness groups without this field set will now error as intended.
* error running consul server in 1.18.0: failed to configure SCADA provider user's home directory path: $HOME is not defined [[GH-20926](https://github.com/hashicorp/consul/issues/20926)]
* server: fix Ent snapshot restore on CE when CE downgrade is enabled [[GH-20977](https://github.com/hashicorp/consul/issues/20977)]
* xds: Make TCP external service registered with terminating gateway reachable from peered cluster [[GH-19881](https://github.com/hashicorp/consul/issues/19881)]
