Here's what's new in v1.18.0:

🚠 Networking

• ⚖️ Load Balancing Redesign: The service load-balancing control-plane in the Cilium agent has been redesigned to reduce memory usage and improve future extensibility of load-balancing features (cilium/cilium#38469, @​joamaki)
• 🔌 Virtual Network Devices: Added support for new virtual network device configurations such as VXLAN in IPsec (VinE) and IPIP tunnels (cilium/cilium#37723, @​ldelossa; cilium/cilium#37346, @​gyutaeb)
• Ⓜ️ Multiple Egress Gateways: Egress Gateways policies can now direct traffic towards multiple gateway nodes (cilium/cilium#39304, @​carlos-abad)
• 🚦 Ingress Rate Limiting: The bandwidth manager now supports ingress rate limiting (cilium/cilium#36351, @​l1b0k)
• 📢 Multi-Device L2 Announcements: The L2 pod announcement feature now supports multiple devices (cilium/cilium#38198, @​dylandreimerink)
• 🏢 Neighbor Subsystem Rework: The neighbor subsystem was made more resilient through a new system that reconciles desired neighbor entries with the kernel state (cilium/cilium#39987, @​dylandreimerink)

🌐 IPv6

• 🚇 Tunneling Underlay: The tunneling datapath mode now supports using an IPv6 network underlay, including when configured with IPsec transparent encryption (cilium/cilium#38296, cilium/cilium#39497, @​pchaigno)
• 💬 Kube Proxy Replacement: Cilium now implements service translation when running on an IPv6 underlay (cilium/cilium#39074, @​pchaigno)
• 📋 Delegated IPAM: When delegating IP address management to a third party plugin, Cilium now configures IPv6 routes for connectivity if the plugin supports IPv6 (cilium/cilium#38249, @​caorui-io, @​kadevu)
• 📦 IP Fragment Support: Cilium now processes ordered IPv6 fragments to apply policy and routing functionality (cilium/cilium#38110, @​gentoo-root)
• 🚪 Egress gateway policies can now match IPv6 address ranges (cilium/cilium#38452, @​rgo3)

🛡️ Policy & Observability

• 🏷️ Policy Names in Hubble-CLI: Show the names of (C)CNPs that allowed or denied traffic when monitoring flows in Hubble (cilium/cilium#39453, @​antonipp)
• 📝 Policy Log Fields: A new free-text log field is added to policies, which is exposed in Hubble flows for easy correlation and searching (cilium/cilium#39902, @​squeed)
• 🛰️ Encapsulated Traffic Decoding: Hubble decodes encapsulated traffic for deeper introspection into traffic flows (cilium/cilium#37634, @​kaworu)
• 🏰 ClusterMesh Policy Restriction: A new option allows the cluster entity to apply only to the local cluster in ClusterMesh environment (cilium/cilium#39338, @​MrFreezeex)
• ✨ Enhanced Policy Dashboard: The Policy section of the Cilium Grafana dashboard has been improved to show more relevant graphs, including policy drops in both directions (cilium/cilium#36492, cilium/cilium#37445, @​squeed)

🌅 Performance

• 📊 Scale Test Results: Cilium implements policies and services up to 45% faster in higher scale environments (Various; @​marseel, cilium/cilium#40227)
• 📦 Image Size Reduction: Docker image sizes are reduced by 32% on arm64 architecture images (cilium/cilium#40005, @​marseel)
• ⚡ Improved Policy Performance: The DNS proxy can process large numbers of IPs faster, and the EndpointSelector match implementation has been optimized (cilium/cilium#39340, @​squeed; cilium/cilium#40414, @​marseel)
• 🪞 EndpointSlice Mirroring for Multi-Cluster Services: Clustermesh mirrors EndpointSlice from the local cluster instead of copying the Service selectors when using the MCS-API controller (cilium/cilium#38596, @​MrFreezeex)
• 🌐 KVStoreMesh Optimization: Cross-cluster state distribution is optimized by only synchronizing identities keyed by ID, not by value (cilium/cilium#36471, @​HadrienPatte)
• 🧠 Egress Gateway Processing: Egress gateway policy processing is significantly improved when matching a large number of pods (cilium/cilium#37714, @​giorio94)
• 🗑️ Optimized Garbage Collection for Connection Tracking: Cilium leverages batched iterators for CTMap GC (cilium/cilium#36288, @​tommyp1ckles)

⚙️ Operations

• 📈 API Server Connections at Scale: Improve kube-apiserver connections behavior at scale through failover and setting better jitter and backoff configurations (cilium/cilium#37601, @​aditighag; cilium/cilium#38031, @​orange30; cilium/cilium#36648, @​wedaly)
• 🔄 ConfigMap Synchronization: New option to automatically synchronize ConfigMap changes into the agent and report metrics for when the effective configuration is different from the desired configuration (cilium/cilium#36510, @​ovidiutirla)
• 🎓 CRD Promotion to Stable: Promote CiliumCIDRGroup, CiliumLoadBalancerIPPool and all BGP CRDs to stable API (cilium/cilium#38940, @​christarazi; cilium/cilium#39090, @​pippolo84; cilium/cilium#37765, @​rastislavs)
• ⛔ Node Taints Handling: The cilium-operator Deployment uses a new default set of taints which avoids deploying to a drained node (cilium/cilium#40137, @​Murat Parlakisik)
