New Mixed Reality Toolkit 3 Repository

[AMollis]

With the creation of the new Mixed Reality Toolkit organization, there now exists two MRTK repositories, one repository for version 3+ and a legacy one for version 2.

Version 3+

New versions of the Mixed Reality Toolkit will be released by the Mixed Reality Toolkit organization using a repository at https://github.com/MixedRealityToolkit/MixedRealityToolkit-Unity. Visit this repository for the latest version of the MRTK project, and when creating new issues or discussion topics for MRTK version 3 or later.

Version 2 (Legacy)

The old MRTK2 repository, https://github.com/microsoft/MixedRealityToolkit-Unity, is remaining under Microsoft's management and will stay on version 2. Microsoft is committed to the next version of MRTK, and recommends applications move to MRTK version 3 or later. However, Microsoft will continue to support and address critical MRTK2 issues, until MRTK2 is deprecated. Please open MRTK2 issues and discussion topics using the old repository.
