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.
Extremely deeply nested React/Ink component trees no longer cause a stack overflow crash. Instead, Claude Code now logs a warning at MAX_TREE_DEPTH and continues rendering the subtree as empty rather than recursing further.
Evidence
New depth guard (search for "ink tree walk stopped at MAX_TREE_DEPTH")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
