age-plugin-yubikey v0.4.0

Changed

• MSRV is now 1.65.0.
• The YubiKey PIV PIN and touch caches are now preserved across processes in most cases. See README.md for exceptions. This has several usability effects (not applicable to YubiKey 4 series):
  • If a YubiKey's PIN is cached by an agent like yubikey-agent, and then age-plugin-yubikey is run (either directly or as a plugin), the agent won't request a PIN entry on its next use.
  • If a YubiKey's PIN was requested by either a previous invocation of age-plugin-yubikey or an agent like yubikey-agent, subsequent calls to age-plugin-yubikey won't request a PIN entry to decrypt a file with an identity that has a PIN policy of once.

Fixed

• Identities can now be generated with a PIN policy of "always" (in previous versions of age-plugin-yubikey this would cause an error).
