The IVI Generation item specifies a set of minimum IVI specification versions with which a specific driver must comply in order to claim compliance with a specific IVI Generation. The following documents describe the IVI Generations and the minimum specification versions required to claim compliance with each.
In 2025 the IVI Foundation released new driver specifications that simplify the requirements for driver compliance. Although these new standards do not invalidate the earlier standards, they provide a streamlined path that aligns with common expectations for general purpose instrument drivers.
In keeping with the IVI policy of dating IVI Generations the year after new specifications are published, these specifications establish IVI Generation 2026. For additional details, see IVI Generation 2026
