From time to time, Microsoft may publish a preview, or pre-release, version of an Open Specifications technical document for community review and feedback. To provide feedback for a preview version of a technical document, please follow the instructions for that document, if provided. Otherwise you can provide feedback by using the Open Specifications Forums.
The preview period for a technical document varies. Additionally, not every technical document will be published for preview.
After the preview period, the technical document is published to the appropriate location in the Open Specifications Library.
