May 2026 monthly summary for kestra-io/kestra: Implemented Helm Chart rendering optimization to prevent unnecessary Service resource creation when only workerGroups are enabled. This reduces unused Kubernetes resources and deployment churn, improving deployment efficiency and cluster cost. Commit d89ba596fea62349ee0ad77e206afee4424a23c0 addresses issue #16032.

November 2025 (kestra-io/docs): Focused on strengthening email security and application security posture through practical security tooling refinements and CSP hardening. Delivered secure email transmission in testing mode with MTA-STS, followed by content fixes and MX-record refinements to improve deliverability security. Implemented and iteratively hardened CSP and security headers via nuxt-security integration, Cloudflare Rocket Loader support, and targeted CSP policy updates, with multiple activations to stabilize security tooling. Result: improved defense-in-depth, better email deliverability assurances, and alignment with security best practices.
