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.

Private key redaction no longer skips blocks

You'll notice
Useful4 Signal2
Redaction

Private key blocks are now reliably redacted instead of occasionally being skipped.

What

The patterns that find PEM private key blocks and replace them with [REDACTED] were shared across calls and carried a search position between them, which could skip a block or mark the wrong boundaries. They are now built fresh on each scan.

Evidence

/-----BEGIN[ A-Z0-9_-]{0,100}?PRIVATE KEY(?: BLOCK)?-----/gi

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

Related

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
