v0.23.3 - Mainnet 15

Mainnet 15

Two major items going out this release.

The first will be the introduction of the new Cadence Storage Layer. This new storage layer will make use of the atree, which will greatly improve the performance of storage interactions with extremly large storage paths. As part of this change, there is a breaking change in relation to the owner field. More on that in the forums

The second being automated Epoch transitions. Epochs will now auto transition once a week with an un-changing node operator list. The network will run the DKG and shuffle clusters each epoch, but node operator changes will not be enabled at epoch boundaries yet. Note that this does not yet include the reward payout, which will still be done manually until we are satisfied with the reliability of the auto epoch transitions.
