[Release] v0.20.0 release schedule

[ysh329]

Last release v0.19.0 was proposed at the end of January. and the release day is 27 Jan., more detail refer v0.19.0 release schedule. It has been almost three months since January. According to our RFC-0067 about quarter-based releases, I hope to release v0.20.0 version at the end of April. 2025. It's meaningful especially for AI infra companies which needs regularly merge with release version.
In order to continue with our agreed release cycle as per discussion in RFC#67 , I'd like to propose a schedule for our next TVM release: v0.20.0.

This schedule is tentative and may change as we progress through the process. In case dates change, this thread will be kept updated.

The proposed schedule is:

• 8 April. 2025 Following three actions should be continuous and coherent:
  • Make version modification twice as two commits: first to v0.20.0 on main branch; second to v0.21.dev0 on main branch in one PR, and merged without squash (required). Why do this first referring discuss on v0.14.0 release: [release][Dont Squash] Update version to 0.20.0 and 0.21.0.dev on main branch #17825
  • A branch v0.20.0 to be created from main on first commit: 1c60502, https://github.com/apache/tvm/tree/v0.20.0
  • A tag named v0.20.0.rc0 created on first commit: https://github.com/apache/tvm/releases/tag/v0.20.0.rc0
