There will generally be three supported versions of Structured Data Files (SDF) at any given time. When a new version is released, a sunset date is announced for the previous version. A version is considered deprecated once a sunset date has been announced for it.
The minimum deprecation period for most versions will be 6 months. While deprecated versions remain available until the scheduled sunset date, users are encouraged to use the deprecation period to migrate to a newer version. After the sunset date, deprecated versions will no longer be available.
A schedule of the currently announced deprecation and sunset dates is provided below:
