Feb 1, 2025February 2025 monthly summary for tailscale/tailscale: Key features delivered include reinstating the High Availability (HA) Ingress controller with multi-endpoint support and exposing an HTTP endpoint on port 80, along with API updates to VIPServices and reconciler triggers on ProxyGroup changes. The Ingress enhancements extend ProxyGroup proxies to include ingress in addition to egress. A major reliability improvement was implemented by making TLS certificate and key storage atomic, preventing misaligned secrets and duplicate issuances. Security and permission hardening were addressed with installer umask set to 022. Containerboot robustness was improved by adding a fallback path for fsnotify watcher creation to prevent crashes. The mkctr dependency was updated to a newer version to capitalize on upstream fixes. Overall, these changes increase reliability, security, and maintainability while delivering tangible business value through more resilient ingress, safer secret management, and up-to-date tooling.

Dec 1, 2024December 2024: Focused on hardening Kubernetes integration for tailscale/tailscale and enhancing observability. Delivered reliability fixes to container boot and tun-mode proxies after runc changes, implemented safe secret handling in non-Kubernetes environments, added permission checks for Secret patching, and gated egress config by deployment context with expanded tests. Introduced Prometheus ServiceMonitor support for proxies, enabling easier monitoring and alerting. Improved Ingress L7 proxy readiness and HTTPS advertisement to advertise endpoints only when ready and configured, plus explicit logging for disabled HTTPS tailnet scenarios. Fixed default STUN port behavior and standardized ProxyGroup hostname formatting. These changes reduce deployment toil, improve security, and enhance operability across Kubernetes deployments.
