     6      **Improved** the ordering of HTTP and TCP envoy filters to improve consistency

     8    - title: "Envoy filter ordering"
     9      content: |
    10        This change impacts internal implementation of how Envoy "filters" are ordered. These filters run in order to implement various functionality.
    11        
    12        The ordering is now consistent across inbound, outbound and gateway proxy modes, as well as HTTP and TCP protocols:
    13        
    14        * Metadata Exchange
    15        * CUSTOM Authz
    16        * WASM Authn
    17        * Authn
    18        * WASM Authz
    19        * Authz
    20        * WASM Stats
    21        * Stats
    22        * WASM unspecified
    23        
    24        This changes the following areas:
    25        * Inbound TCP filters now place Metadata Exchange before Authn.
    26        * Gateway TCP filters now place stats after Authz, and CUSTOM Authz before Authn.
