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 v2.1.228

Half-typed exponents no longer break streaming tool input

You'll notice
Useful2 Signal1
Tool Calls

A half-typed exponent while a tool call streams no longer produces a malformed value.

What

While a tool call is still streaming, the repair step for incomplete JSON now discards a trailing number ending in +, e or E, not just one ending in . or -, so a partly written exponent no longer parses into a malformed value.

Evidence

r.push({ type: "number", value: a });

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