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.

Claude Code v2.1.246

Pathological markdown no longer crashes rendering

You'll notice
Useful3 Signal1
Rendering

Wildly malformed markdown now falls back to plain text instead of crashing your display.

What

Text that overflows the markdown parser now degrades to a single plain paragraph and logs the overflow instead of throwing.

Details
  • The quick "does this look like markdown at all" check now examines the whole string rather than the first 500 characters, and runs after the cache lookup.
Evidence

marked.lexer overflow on

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