    11  - title: Inbound Cluster Name Format
    12    content: |
    13      The format of inbound Envoy cluster names has changed. Previously, they included the Service hostname
    14      and port name, such as `inbound|80|http|httpbin.default.svc.cluster.local`. This lead to issues when multiple
    15      Services select the same pod. As a result, we have removed the port name and hostname - the new format will
    16      instead resemble `inbound|80||`.
    17  
    18      For most users, this is an implementation detail, and will only impact debugging or tooling that directly
    19      interacts with Envoy configuration.
