 Backports of PRs to the beta branch are usually only done to fix regressions.
 Getting a PR backported to the beta branch involves the following process:
 
-1. Add the label [`beta-nominated`](https://github.com/rust-lang/rust/pulls?q=is%3Apr+label%3Abeta-nominated) to the PR to be backported.
+1. Add the label [`beta-nominated`](https://github.com/rust-lang/rust/pulls?q=is%3Apr+label%3Abeta-nominated+-label%3Abeta-accepted) to the PR to be backported.
    This marks the PR as in the state that it needs attention from the appropriate team to decide if it should be backported.
-   It is also suggested to apply the `I-*-nominated` and the appropriate `T-` (team) label: that'll _really_ get their attention!
-   Anybody with triage access is free to make these labels.

    Otherwise they should remove the nominated label.

    3. (Recommended) Run some tests locally.
       It is not uncommon that the backports may not apply cleanly, or the UI tests need to be re-blessed if there are differences in the output.
    4. Open a PR **against the beta branch** with a title that starts with `[beta]` (so reviewers can see its specialness).
    5. List all of the PRs being backported in the PR description.
       [Here's an example](https://github.com/rust-lang/rust/pull/64097).
 
 4. A reviewer (typically from the release team) needs to verify that the backport looks correct and that it's submitted to the beta branch.
