May 2026 monthly summary for kamailio/kamailio: focused on TLS reliability, documentation enhancements, and cross-version compatibility. Key features delivered include updated CRL parameter documentation clarifying that CRL is a folder containing PEM files with a .pem extension. Major bugs fixed include improving TLS/OpenSSL compatibility for older OpenSSL versions (pre-3.2) by introducing conditional compilation guards to wrap TLS 1.3 improvements. These changes reduce build-time failures on legacy environments, streamline TLS configuration for deployments, and enhance maintainability and supportability for customers using older TLS stacks.

April 2026: Delivered a suite of TLS security, stability, and performance improvements for kamailio/kamailio with a focus on WolfSSL integration, multi-process/thread handling, and ecosystem updates. Implemented RFC 7512-based PKCS#11 key loading, improved reload behavior, and extended TLSv1.3 visibility. Hardened key-loading paths in multi-process setups, tightened SNI-key binding, and reduced reinitialization overhead for faster startup. Updated WolfSSL to a stable release and aligned MariaDB SSL behavior with Connector/C 3.4+. Enhanced observability and stability across TLS, with targeted cleanup and default threading refinements.
