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.

Layout results cached on nodes instead of a side table

Under the hood
Useful1 Signal0
Terminal Rendering

Layout results are cached on each node rather than in a shared table.

What

The terminal renderer now stores each node's computed layout on the node itself rather than in a separate lookup table, and the layout engine carries its own counters for nodes visited, measure calls, cache hits and live nodes in place of module-level functions.

Evidence

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