From cb462adeb9d842bc161f67743e10ae42cc274b29 Mon Sep 17 00:00:00 2001 From: Christopher Tauchen Date: Thu, 16 Jul 2026 09:30:24 +0100 Subject: [PATCH] Add KubeVirt VM live migration to CE 3.23 release notes The KubeVirt VM live migration over BGP feature shipped in Calico Enterprise 3.23 (based on Calico Open Source 3.32) and is documented under networking/kubevirt, but it was omitted from the "New features and enhancements" list in the 3.23 release notes. Add an entry in the 3.23.0-2.0 feature block linking the KubeVirt networking overview and the BGP live-migration routing guide.
