# 3.0.0 __added__ - Added TypeScript support (#104) - Added support for excluding wordlists from packages (#105) __changed__ - Changed `mnemonicToSeed` to use async, sync version moved to `mnemonicToSeedSync` (#104) __removed__ - Removed explicit hex methods (use `toString('hex')` on the Buffer) (#104) # 2.3.1 __breaking changes__ 9-letter mnemonics can no longer be geerated and calling `validateMnemonic` will always return false. This was [fixed in the BIP as a patch](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki#generating-the-mnemonic), so we had to follow suite.
