    * 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?

No auto-vectorization yet, but you may find this illuminating: https://www.stylewarning.com/posts/nbody

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.

Looks like you use it explicitly?

CL can be used pretty much anywhere nowadays, even on the web with ECL wasm compilation.

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

I have a todo list longer than the Tour de France I want to tackle first!
