*Changes that are expected to cause an incompatibility if applicable; deployment changes are likely required*

* ext_authz: fixed skipping authentication when returning either a direct response or a redirect. This behavior can be temporarily reverted by setting the ``envoy.reloadable_features.http_ext_authz_do_not_skip_direct_response_and_redirect`` runtime guard to false.

* access log: fix ``%UPSTREAM_CLUSTER%`` when used in http upstream access logs. Previously, it was always logging as an unset value.
* aws request signer: fix the AWS Request Signer extension to correctly normalize the path and query string to be signed according to AWS' guidelines, so that the hash on the server side matches. See `AWS SigV4 documentaion <https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html>`_.
* cluster: delete pools when they're idle to fix unbounded memory use when using PROXY protocol upstream with tcp_proxy. This behavior can be temporarily reverted by setting the ``envoy.reloadable_features.conn_pool_delete_when_idle`` runtime guard to false.
* ext_authz: fixed skipping authentication when returning either a direct response or a redirect. This behavior can be temporarily reverted by setting the ``envoy.reloadable_features.http_ext_authz_do_not_skip_direct_response_and_redirect`` runtime guard to false.
* hcm: remove deprecation for :ref:`xff_num_trusted_hops <envoy_v3_api_field_extensions.filters.network.http_connection_manager.v3.HttpConnectionManager.xff_num_trusted_hops>` and forbid mixing ip detection extensions with old related knobs.
* listener: fixed an issue on Windows where connections are not handled by all worker threads.
* xray: fix the AWS X-Ray tracer bug where span's error, fault and throttle information was not reported properly as per the `AWS X-Ray documentation <https://docs.aws.amazon.com/xray/latest/devguide/xray-api-segmentdocuments.html>`_. Before this fix, server error was reported under 'annotations' section of the segment data.
