What states do not require a unanimous verdict in a federal jury trial?

In federal jury trials, a unanimous verdict is required by federal law. However, in state courts, a few states do allow non-unanimous verdicts in certain circumstances. For instance, Louisiana and Oregon previously permitted non-unanimous jury verdicts in felony cases, but changes in state law have since moved towards requiring unanimity. It's important to note that this does not apply to federal trials, where unanimity is mandatory regardless of state practices.
