Most users of otp should be able to upgrade safely. I'm happy to say otp is a stable library and is being used by many groups successfully.

Changes since v1.0.0:

• #30: Increases default secret size from 10 bytes to 20 bytes. This may effect storage of newly generated secrets, eg in a SQL database backend.
• #25: Improved interoperability with broken base32 encoders.
• #31: Bugfix: Check for a zero default Digits in hotp.Generate.
• #21: Adds otp.key.URL() method.

Non-functional changes since v1.0.0:

• #27: Add additional test cases.
• #28 and #23: Update Travis CI Settings.
• #23: gofmt repo.
