• When changing passphrases: Subkeys with GNU_DUMMY_S2K will now be ignored

0.2.3

• Introduce new simplified decryption API
  The new API (withOptions(ConsumerOptions)) resembles the encryption API and is more friendly to dynamic construction of decryption properties
  The old API has been deprecated and will be removed in a future release
• Add example package in the JUnit tests
  This package contains always-up-to-date usage examples for the PGPainless' API and various use cases
