2.22.0

[2.22.0] - 2021-01-27

Added:

• Added the alias method to LDClient. This method can be used to associate two user objects for analytics purposes. When invoked, this method will queue a new alias event to be sent to LaunchDarkly.
• Added the autoAliasingOptOut configuration option. This can be used to control the new automatic aliasing behavior of the identify method; by passing autoAliasingOptOut: true, identify will not automatically generate alias events.

Changed:

• LDClient's identify method will now automatically generate an alias event when switching from an anonymous to a known user. This event associates the two users for analytics purposes as they most likely represent a single person.
