Ethereum core developer Tim Beiko express that the Shapella (Shanghai/Capella) upgrade is scheduled for Feb 28. 

Ethereum's Shapella Upgrade Receives New Date, Allowing for Un-Staking ETH

The Shapella network upgrade will activate on the Sepolia network at epoch 56832.

The upgrade is only for the Sepolia network and a subsequent upgrade for the Goerli network would be introduced in March. 

The upcoming Ethereum hard fork will be named Shanghai and Capella, with Shanghai referring to the fork on the execution client side and Capella being the upgrade name on the consensus layer client side.

Ethereum Improvement Proposals (EIP) will bring some significant changes to the execution layer, including Warm Coinbase and Beacon chain push withdrawals. With push withdrawals, validators will be able to withdraw from the beacon chain to the EVM through a new "system-level" operation type. On the other hand, WARM Coinbase0 could be a game-changer, potentially lowering network fees for key network participants known as builders.

Software Builders use Coinbase software to receive new tokens on the network, and every transaction on the platform needs to interact with it multiple times. Initially, the first interaction incurs higher costs as the software needs to "warm" up, with fees decreasing as the interactions increase. However, EIP-3651 will introduce a change where the Coinbase software remains warm from the start, leading to lower gas fees for accessing it.

Ethereum Shapella upgrades major changes to the consensus layer including full and partial withdrawals for validators and independent states and blocks historical accumulators, replacing the original singular historical roots. 

The upgrade would enable validators to withdraw their staked Ether (ETH) from the Beacon Chain to the execution layer. the upgrade would bring changes to the execution layer and consensus layer, making it a key upgrade following the Merge. 

Furthermore, speakers and non-speakers who operate nodes, upgrade their nodes to the most recent Ethereum client version to take advantage of the Sepolia upgrade after the deployment of the Sepolia upgrade. the next step would be the release of the Shanghai upgrade on the Ethereum Goerli test network expected to commence in March.
