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 caching moved onto the nodes themselves

Under the hood
Useful1 Signal0
Terminal Rendering

Layout data moved onto each node, and mixing layout configurations now raises an error.

What

Cached layout rectangles and pending-clear tracking now live on each layout node rather than in a side lookup table, and the counters for nodes visited, measure calls and cache hits moved onto the layout configuration object. Adding a child created under a different configuration now raises an error instead of producing inconsistent layout.

Evidence

insertChild: child was created with a different Config

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