# Change Log

## [3.5.0] - 2026-10-22

- Fix: footer link is keyboard-focusable (removed `tabindex="-1"`) and its `aria-label` announces that it opens in a new tab, in all translations [#204]

## [3.4.1] - 2026-10-19

- Fix: regression in V1 challenge detection [#202]

## [3.4.0] - 2026-10-15

- Fix: `./i18n/*` export `types` condition points to `dist/i18n/*.d.ts` instead of the non-existent `dist/external/*.d.ts` [#200]
- Fix: support the `form` attribute to associate the widget with a `<form>` it is not nested in [#201]

## [3.3.0] - 2026-10-05

- Fix: SHA key derivation hashes the full digest each round and truncates once, matching altcha-lib and the server ports (SHA-384/512 and any `keyLength` below the digest size with `cost > 1` previously failed server verification)
- Fix: PBKDF2 supports any `keyLength` (uses `deriveBits` instead of an AES-GCM key)
- Fix: built-in `deriveKey` functions reject unsupported algorithm names
- Fix: `verifySolution` requires the re-derived key to match the signed `keyPrefix`, rejects malformed `derivedKey`/`counter` values, and validates secrets and `hmacAlgorithm`
- Fix: `createChallenge` validates its options (`keyPrefixLength` below the derived key length, non-empty hex `keyPrefix` lowercased before signing, positive integer `cost`/`keyLength`, valid `counter` and `expiresAt`)
- Fix: `solveChallenge` fails fast on an invalid `keyPrefix`
- Fix: `hexToBuffer` rejects non-hex input; canonical JSON keeps `__proto__` keys
- Fix: `verifyServerSignature` validates `algorithm` and `hmacSecret`, handles a missing signature, and uses exact expiry
- Fix: obfuscation plugin encrypts with the full derived key instead of a `keyPrefixLength`-sized prefix
