Steel Bank Common Lisp version 2.6.7 | Hacker News

Steel Bank Common Lisp 2.6.7 adds SB-SIMD support for ARM64.

The release also brings AVX512 support on x86-64 and broader SIMD instruction coverage on both platforms.

The update should improve performance for compute-heavy Lisp workloads and reflects continued optimization work in SBCL.
