[DEV][Announcement] Main now transitions to Unity

[tqchen]

Dear community:

Following the vote to transition main to unity branch. We are working to transition main to unity. I am happy to announce that as of now, the main branch is updated to the unity branch and incorporates the all the latest changes in main branch.

Backup branches

We created the following backup branches.

• Use branch https://github.com/apache/tvm/tree/main-before-unity-switch, for the main branch before the transition.
• Use branch https://github.com/apache/tvm/tree/unity-before-switch for unity branch before the transition

Updating existing PRs

• If you have PRs to main, you can try rebase via

git rebase --onto upstream/main upstream/main-before-unity-switch

• Outstanding PRs to unity branch should change the base to main, and run

git rebase --onto upstream/main upstream/unity-before-switch

• All future unity PRs should be sent to main instead

Guideline for using the latest main

Likely things will continue to function whether you are using main or unity features. Thanks to @Hzfengsy for confirming all the main testcases on the unity branch before we carry out the transition. But we also understand that there will be some period of time that we adjust, so feel free to use the forum post and other means to work with the community.

This is an exciting milestone for the community and helps us to collectively evolve the project to empower genAI, looking forward to working with everyone to bring more exciting changes through unity flow
