5.12.0

[5.12.0] - 2020-01-06

Added:

• IUserBuilder.Secondary is a new name for SecondaryKey (for consistency with other SDKs), and allows you to make the secondary attribute private.
• User.Secondary (same as SecondaryKey).
• FeatureFlagsState now has a Builder method for constructing a new instance (useful in testing). (#125)

Deprecated:

• IUserBuilder.SecondaryKey, User.SecondaryKey.
