OpenSSL 4.1.0 Beta 2 has been released, featuring native support for DTLS 1.3 and enhanced integration of NIST's post-quantum cryptography algorithms. This beta version, which is intended for testing rather than production use, includes 115 commits from 37 contributors and introduces several smaller features such as GREASE support and initial support for the Elbrus2000 architecture. While it improves performance for post-quantum algorithms, users are advised to be cautious of breaking changes, such as the need for a new CPAN module and the removal of certain Windows targets. OpenSSL 4.1 is a non-LTS release with an end-of-life in November 2027, prompting teams seeking long-term stability to consider the upcoming LTS release, version 4.2, expected in April 2027

OpenSSL 4.1.0 Beta 2 adding native DTLS 1.3 support and deeper integration of NIST's post-quantum cryptography algorithms. The build is intended for testing rather than production, and it packed 115 commits across 250 files by 37 contributors between the two betas. Smaller additions include RFC 8701 GREASE support, DTLS in the SSL listener API, IKEv2 KDF, initial Elbrus2000 architecture support, and performance speedups for ML-DSA and ML-KEM operations. As a non-LTS line with an end-of-life of November 2027, 4.1 gives teams wanting long-term stability a clear target in the 4.2 LTS release due April 2027.
