Next steps

• Test the release
• If this is an 'alpha' release, you can just merge the pull request.
• Otherwise:
  • For any added commits, run the release workflow in 'rc' mode again
  • After testing, _ensure that this PR is mergeable to _, then run the release workflow in 'release' mode
  • Once the final release workflow finishes it will create a GitHub release for you. Then:
    • Sanity check the build artifacts:
      • pip install: does it install and run?
      • cargo install of cli tool: does it install and run?
      • C++ SDK zip: does it contain rerun_c for all platforms?
    • Edit and publish the GitHub release:
      • Do NOT create a GitHub release draft yourself! Let the release job do it.
      • Populate the release with the changelog and a nice header video/picture
      • Make sure is checked
