Summary of Changes

Major Changes:

  • Add dynamic flowlog exporters configured by yaml file (configmap) without a need of agent restart. (#28873, @marqc)
  • Add support for extending ClusterMesh to 511 clusters
    By setting the flag --max-connected-clusters=511, a new cluster will be able to connect to a ClusterMesh with up to 511 clusters. If enabled, the number of possible cluster-local identities will be reduced to 32,768. This feature can only be enabled on new clusters, and all clusters in the ClusterMesh must share the same configuration. (#27520, @thorn3r)
  • Add support for Gateway API v1.0 (#28836, @sayboras)
  • k8s: add support for k8s 1.29.0 (#29473, @aanm)

  • Add a mode where routing is delegated to another CNI plugin. This enables support for using AWS security groups when chaining Cilium on top of AWS VPC CNI. (#29111, @Alex-Waring)
