Ah, so tzdata2020c is done:

https://bugs.openjdk.java.net/browse/JDK-8254982

and tzdata2020d is presumably in progress:

https://bugs.openjdk.java.net/browse/JDK-8255226

I presume for backports we could just do one further change
that is marked as both 2020c & 2020d. I'd like 2020b to stay
as is because it's already well tested.

Thanks,
