 Release Notes
 =============
 
-This is the release of Gnuk, version 1.2.19, which has major
-incompatible changes to Gnuk 1.0.x.  Specifically, it now supports
-overriding key import, but importing keys (or generating keys) results
-password reset.  Also, you need to import private keys before changing
-your password.  Please update your documentation for Gnuk Token, so
-that the instruction of importing keys won't cause any confusion.

 than 8 seconds to sign/decrypt.  Key generation of RSA-4096 just fails,
 because the device doesn't have enough memory.
 
-It supports new KDF-DO feature.  Please note that this is
-experimental.  To use the feature, you need to use newer GnuPG (2.2.6
