**Full Changelog**: https://github.com/NVIDIA/Megatron-Energon/compare/2.1.1...2.2.0

Version 2.2.0 introduces support for video files in your dataset and adds new samples and dataset classes for video question answering (VidQA).
The new classes are: `VidQASample` and `VidQAWebdataset`.

If you have videos in your dataset shards, those should now automatically be decoded and yield a `VideoData` object, which contains the frames and the audio data as well as some meta data.

You can find the installable package here: https://pypi.org/project/megatron-energon/2.1.1/
