- Add support for Bitcoin Taproot addresses (P2TR)
- Add support for [BIP-0086](https://github.com/bitcoin/bips/blob/master/bip-0086.mediawiki)
- Add support for [bech32m](https://github.com/bitcoin/bips/blob/master/bip-0350.mediawiki)
- Add support for Algorand 25-word mnemonic
- Add support for Solana SPL token
- P2WPKH decoding/encoding methods don't need anymore the witness version as parameter, since it's fixed to zero internally (it can still be passed without errors though, it's just ignored)
- Use Cryptodome if *ripemd160* and *sha512_256* algorithms are not available in *hashlib*
- Add documentation using sphinx
- Some refactoring for mnemonic module
- **Breaking changes**:
- Mnemonic-specific checksum exceptions (i.e. `Bip39ChecksumError` and `MoneroChecksumError`) were replaced by the common `MnemonicChecksumError`
