Major Changes

Updated to Cadence version v0.23.0, which contains a breaking change for the Public Key API

There has also been a lot of improvements made to the mTrie/merkle tree storage methods, specially made around the Write Ahead Log, and Checkpointing logic. The speed improvements here are mostly noticeable for node operations side and will not be DAPP facing.

There will be an internal concept change, which will better define the concept of "Weight" in the protocol. This changed required some renaming of Stake → Weight (Node level breaking change). This means that the read the new protocol state, it will require a matching node version that has the same conceptual understanding of Stake vs Weight.

Lastly, there is a change that will make to add the code necessary for Variable Transaction Fees, but this feature will not be enabled until a community vote has been held.
