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.

#

  • Fixed crash when changelog cache file is corrupted or unreadable. The release notes loader (de2() at line 460474) now catches exceptions during changelog parsing and gracefully returns an empty result instead of crashing. This prevents startup failures when the ~/.claude/cache/changelog.md file is malformed.
Evidence

de2() at line 460474 (release notes loader, reads from "cache", "changelog.md")

Before (v2.1.0):

function de2(A) {
  let Q = k6A();
  if (!Q) return [];
  let B = eH1(Q),  // Could throw if file is corrupted
    G = [],
    ...
}

After (v2.1.1):

function de2(A) {
  let Q = k6A();
  if (!Q) return [];
  let B;
  try {
    B = eH1(Q);
  } catch {
    return [];  // Gracefully handle corrupted changelog
  }
  let G = [],
  ...
}

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

No official entry

Not individually listed upstream

v2.1.1 does not have its own entry in Anthropic’s official changelog, because prerelease builds are often folded into a neighbouring release. Browse the full changelog for the closest official notes. Everything else on this page came out of the bundle instead, which is why the two lists don't match.

System prompt
