Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

This project is part of the Intel® Video Processing Library (Intel® VPL), a programming interface that provides access to hardware accelerated video decode, encode, and frame processing capabilities on Intel® GPUs to support AI visual inference, media delivery, cloud gaming, and virtual desktop infrastructure use cases.
