DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Concurrency docs say available CPUs

You'll notice
Useful2 Signal1
Elsewhere

Parallel agent limits are now described as capped by available CPUs, not total cores.

What

The explanation of how many agents run at once now states the cap as min(16, available CPUs - 2) rather than referring to cpu cores.

Evidence

min(16, available CPUs - 2)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
