+## [2.11.0] - 2025-06-18
+
+Coil Egress now offers dual-stack support, enabling it to handle both IPv4 and IPv6 traffic within a single Egress. We have also implemented a new iptables rule in Egress pods (which are managed by the Egress resource and function as gateways to external networks) to drop invalid packets. Additionally, Egress-related metrics have been updated:
+
+- New metrics have been added to count invalid packets dropped by this new iptables rule.
+- The coil_egress_nftables_masqueraded_packets and coil_egress_nftables_masqueraded_bytes metrics have been updated to include support for IPv6.
+
+This release doesn't have any breaking changes.
