Security fixes include: corrected basic constraint path validation per RFC 5280 (CVE-2026-42789), and removal of legacy hostname verification fallback to subject common name in favor of RFC 9525 compliance (CVE-2026-42790, a potential incompatibility). OCSP responder certificate expiration is now properly checked before acceptance. Other fixes address a compiler bug that could invert boolean expression values, a compiler crash with native records, incorrect native record comparison results in the runtime system, SCTP peeloff IPv6 socket option inheritance, and a snmpm_usm crash on unknown user/engineID combinations. ## Full article daily.dev links to this article rather than hosting it.
