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

minor_behavior_changes:
# *Changes that may cause incompatibilities for some users, but should not for most*
- area: connection pool
  change: |
    Increase granularity mapping connection pool failures to specific stream failure reasons to make it more transparent why
    the stream is reset when a connection pool's connection fails.
- area: uhv
  change: |
    Preserve case of %-encoded triplets in the default header validator. This behavior can be reverted by setting runtime flag
    ``envoy.reloadable_features.uhv_preserve_url_encoded_case`` to false, in which case %-encoded triplets are normalized
    to uppercase characters. This setting is only applicable when the Unversal Header Validator is enabled and has no effect otherwise.
- area: uhv
  change: |
    Allow malformed URL encoded triplets in the default header validator. This behavior can be reverted by setting runtime flag
    ``envoy.reloadable_features.uhv_allow_malformed_url_encoding`` to false, in which case requests with malformed URL encoded triplets
    in path are rejected. This setting is only applicable when the Unversal Header Validator is enabled and has no effect otherwise.

bug_fixes:
# *Changes expected to improve the state of the world and are unlikely to have negative effects*

- area: upstream
  change: |
    removed runtime key ``envoy.reloadable_features.fix_hash_key`` and legacy code paths.

new_features:
- area: http
  change: |
    added Runtime feature ``envoy.reloadable_features.max_request_headers_size_kb`` to override the default value of
    :ref:`max request headers size
    <envoy_v3_api_field_extensions.filters.network.http_connection_manager.v3.HttpConnectionManager.max_request_headers_kb>`.
- area: redis_proxy
  change: |
    added new configuration field :ref:`key_formatter
    <envoy_v3_api_field_extensions.filters.network.redis_proxy.v3.RedisProxy.PrefixRoutes.Route.key_formatter>` to format redis key.
    The field supports using %KEY% as a formatter command for substituting the redis key as part of the substitution formatter expression.
