Sourced from github.com/ProtonMail/go-crypto's releases.

v1.1.0-alpha.1

What's Changed

Removes the openpgp.VerifyDetachedSignatureAndSaltedHash function and the packet.SaltedHashSpecifier as they are no longer required. They were introduced for verifying the headers in cleartext messages. However, in the latest crypto-refresh specification, cleartext message headers were dropped.

Full Changelog: v1.1.0-alpha.0...v1.1.0-alpha.1

v1.1.0-alpha.1-proton

This pre-release is v1.1.0-alpha.1 with support for symmetric keys and automatic forwarding, both of which are not standardized yet.

v1.1.0-alpha.0

What's Changed

This major pre-release adds full support for the OpenPGP crypto refresh. In addition, the pre-release introduces an improved non-backwards compatible v2 API. The API in the openpgp package remains fully backwards compatible while the new v2 API is located in a separate v2 package in openpgp.
