it seems 1 year no update, maybe we should replace it

In adiition:

• Substrate main branch just upgrade grandpa to 0.16.2 Bump grandpa to 0.16.2 paritytech/substrate#13622 Do we need upgrade PRuntime V0 as well?

Removed.

Fixed.

A bit tricky for this one. Max size of 82526 is obviously not acceptable for phat contracts. They hard-coded a limitation in the tests and we can not change it. Let's make a workaround temporarily in order to pass the testing and discuss with parity for a better solution. I've left a message there on the parity's Element group.

• Substrate main branch just upgrade grandpa to 0.16.2 Bump grandpa to 0.16.2 paritytech/substrate#13622 Do we need upgrade PRuntime V0 as well?

No feature changes from 0.16.1 to 0.16.2. So I think we can ignore it.
