Release Notes

Batch Container

High-Level Summary

This release provides internal bug and security fixes. It is recommended that customers on previous releases upgrade to this version.

Important Notices

The legacy V1 API and related output formats is no longer supported. V1 examples have been removed from all batch container documentation and will no longer work. We recommend use of the V2 API and the config.json for all supported features object as documented in the Speech API guide for 8.1.2.

It is now necessary to use processors that support Advanced Vector Extensions 2 (AVX2) when running the container in order to take advantage of latest performance optimisations.
