  • Add new API, supporting incremental absorption of associated data, encryption of plaintext and decryption of ciphertext. Remove oneshot function -based API of encryption/ decryption.
  • Update tests, benchmarks and examples to switch to new API.
  • Add more tests to ensure that state transition works as envisioned and API can't be misused.
