* dns: PTR record queries now return answers that contain the Consul datacenter as a label between `service` and the domain. [[GH-6909](https://github.com/hashicorp/consul/pull/6909)]
* agent: The ACL requirement for the [agent/force-leave endpoint](https://www.consul.io/api/agent.html#force-leave-and-shutdown) is now `operator:write` rather than `agent:write`. [[GH-7033](https://github.com/hashicorp/consul/pull/7033)]
* intentions: Change the ACL requirement and enforcement for wildcard rules. Previously this would look for an ACL rule that would grant access to the service/intention `*`. Now, in order to write a wildcard intention requires write access to all intentions and reading a wildcard intention requires read access to any intention that would match. Additionally intention listing and reading allow access if the requester can read either side of the intention whereas before it only allowed it for permissions on the destination side. [[GH-7028](https://github.com/hashicorp/consul/pull/7028)]
* telemetry: `consul.rpc.query` has changed to only measure the _start_ of `srv.blockingQuery() calls`. In certain rare cases where there are lots of idempotent updates this will cause the metric to report lower than before. The counter should now provides more meaningful behavior that maps to the rate of client-initiated requests. [GH-7224](https://github.com/hashicorp/consul/pull/7224)
