Today we would like to announce MRTK3 as the name that we will be calling the next version of MRTK! With the next version of MRTK gleaming in the horizon, we want to remind everyone how important the MRTK community's contributions have been to shaping MRTK into what it is today and what it is going to be in the future. We would love if you looked over the MRTK3 section of the MRTK Roadmap as well as watch our GDC 2022 Creating Cross-Platform Mixed Reality Experiences panel, and then bring your thoughts and ideas to the MRTK repository's Discussions board or file a Feature Request issue and tag 'MRTK3'! We are looking forward to sharing more MRTK3 information with you in the near future and hearing your feedback.
