Steel Bank Common Lisp version 2.6.7

Fun fact I learned from a Func Prog podcast: the name Steel Bank is a play on it's origin as Carnegie-Mellon Common Lisp (Carnegie made his fortune in Steel, while Mellon did so with Banks):

Steel Bank Common Lisp is what Hacker News uses.

I discovered this while doing some research for a post the other day: https://vale.rocks/posts/hacker-news

    * the SB-SIMD contrib now supports ARM64. (Thanks to Sylvia Harrington)
    * AVX512 instructions are now supported on X86-64. (Thanks to Robert Smith and Arthur Miller)
    * additional support for SIMD instructions on ARM64 and X86-64. (Thanks to Arthur Miller)

These seem like pretty awesome additions. Does anyone know how SIMD works in SBCL? Is this at the codegen layer? i.e. can it auto-vectorize or anything like that? Or are these intrinsics you have to explicitly ask for?

I wonder sometimes how the world would look like if lisp won and the unit of deployment was a lisp machine image, if that makes sense. How would a kubernetes optimized for lisp look like? How would AWS EC2 look like? etc.

If any SBCL dev is here, please add documentation for how to use the memory arena feature. The only doc is an very old proposal document.

SB-MANUAL looks great—having the manual available through docstrings and SLIME should make SBCL development much more pleasant.

If memory serves, traditionally, CCL (Clozure Common Lisp [0]) had better support for Windows but SBCL was unbeatable for speed. Is that still the case?

Great to see the project is still going strong, I kinda want to try CL but I always feel like I don't have a great use-case.

I'm going pretty deep on Lisp on accident - can anybody give me more context on this?

Great semver number
