- The new group notifications toggle from v24.0.0 added an Alembic
migration that accidentally used `5c68d45c80f0` as the `down_revision`.

- That revision is already the `down_revision` of `72b37bb4119c`, which
is from Jun 2025 so has already been applied on many instances.

- The correct revision order is:

  ```
  5c68d45c80f0 (Sep 2023)
  72b37bb4119c (Jun 2025)
  c3feb26c7041 (Feb 2026, datetime UTC)
  dfbc96c5211f (The new notifications migration)
  ```
