Hi!
We're happy to announce that Tarook v15.0.0 [1][2] has been published!
Some notable changes, amongst others:
* Calico is now deployed in eBPF dataplane mode.
o Clusters with IPv6 enabled previously were configured to use the
ipvs mode of kube-proxy which got deprecated with Kubernetes
v1.35 [3].
Due to that deprecation, changes to the CNI setup were necessary.
Calico's eBPF dataplane mode has been chosen due to its
performance benefits.
A migration path for existing clusters has been implemented.
o kube-proxy is disabled by default now as it interferes with
Calico running in eBPF dataplane mode.
* When upgrading an existing cluster to this release, changes to the
cluster repository's flake.nix are necessary.
* The necessary changes for Ubuntu 26.04 have been implemented.
* Routes to the Kubernetes Service IP range are propagated by Calico
to BGP peers by default now.
* Components of the monitoring stack can now be freely configured.
* Support for Envoy Gateway as Gateway API integration has been added.
o A migration for clusters already using the Calico Ingress
Gateway has been implemented.
* The "sntrup761x25519-sha512" post-quantum key exchange algorithm has
been enabled for SSH.
Some notable changes specifically for clusters on OpenStack or Proxmox:
* The bird setup has been made compatible with bird3. Debian 13 can
now be used for gateway nodes.
* OpenStack Anti-Affinity-Groups can now be configured for any node.
* Support for IPSec has been dropped.
Check out the release notes [4] to get information about all the other
changes and for more details!
Best regards
