-- Notify [@pnkfelix](https://rust-lang.zulipchat.com/#narrow/pm-with/116083-user116083) about accepted [`beta nominated`](https://github.com/rust-lang/rust/issues?q=is%3Aall+label%3Abeta-nominated+-label%3Abeta-accepted) and [`stable nominated`](https://github.com/rust-lang/rust/issues?q=is%3Aall+label%3Astable-nominated+-label%3Astable-accepted) without `beta-accepted` and `stable-accepted` label. For that compare these issues with list meeting's accepted nominations.
-- Notify @pnkfelix about rejected [`beta nominated`](https://github.com/rust-lang/rust/issues?q=is%3Aall+label%3Abeta-nominated+-label%3Abeta-accepted) and [`stable nominated`](https://github.com/rust-lang/rust/issues?q=is%3Aall+label%3Astable-nominated+-label%3Astable-accepted) still with the nominated label. For that compare these issues with last meeting's rejected nominations.
