This guide provides an overview on versioning in Embedded Signup. The versioning cadence will align with Graph API. The versions are not exclusive, partners can gradually roll out a new version of ES to reduce risk. The Embedded Signup version is determined inside of the extras object of the implementation code.

Note: The refreshed UI, currently available in the public preview, will be rolled out to all versions of Embedded Signup in early September.
