Here's some text for "what's new 3.13" describing the Tier 2 and JIT architecture. It's not complete and missing references and details -- we can always improve it later, but suggestions for improvements right now are also welcome.
I used "JIT" as the headline, rather than "Tier 2" or "micro-ops", mostly because that's apparently the catchier phrase, and also because the JIT gives the best performance. (Numbers are TBD -- they will improve over the next few months as more of the optimization pipeline lands.)
It's a bit speculative because gh-114059 (@Fidget-Spinner's optimizer) hasn't landed yet -- we can wait merging this until it has.
Once this is in, I am hoping (based on an email exchange with @Yhg1s) that this work can also be highlighted in the alpha release announcements.
