description: |
  Removed the era case combinators `caseByronOrShelleyBasedEra` and `caseShelleyToBabbageOrConwayEraOnwards`, along with the internal `caseShelleyEraOnlyOrAllegraEraOnwards`, and the now-empty `Cardano.Api.Era.Internal.Case` module. Use `inEonForEra` / `inEonForShelleyBasedEra` with the appropriate eon, or match on the era constructors where both branches need era constraints.
