• Make att_stmt optional in make_credential::Response, preparing for CTAP 2.2

0.1.2 - 2022-03-07

Yanked 0.1.1 instead of 0.1.0 by mistake, re-releasing.

0.1.1 - 2022-03-07

• add CTAP2.1 Selection command
• add CTAP2.1 options

We will release this and yank 0.1.0, to avoid a minor version bump.

0.1.0 - 2022-03-05

• use 2021 edition
• make CTAP1 and CTAP2 more homogeneous
• add Authenticator traits
• lower MAX_CREDENTIAL_ID_LENGTH to 255 bytes, which seems to be the limit used in practice (coming from U2F's size bytes)
• replace MESSAGE_SIZE with a theoretical and a realistic constant
• use iso7816 0.1.0 release
