This release focuses on security hardening and operational reliability. Core updates introduce a regex length limit to reduce resource-exhaustion risk. Plugin updates improve error consolidation (show_first), reduce misleading SOA warnings, add Kubernetes API rate limiting, enhance metrics with plugin chain tracking, and fix issues in azure and sign. This release also includes additional security fixes; see the security advisory for details.
