According to a Jan. 31 post by Ethereum Foundation developer Parithosh Jayanthi, the "Zhejiang" public withdrawal test net will launch on Feb. 1 at 15:00 UTC. Six days after Zhejiang, the Shanghai and Capella testnets will also be triggered at epoch 1350. Jayanthi noted:

"This is also a great opportunity for all tools to test out how they want to collect, display and use the withdrawal information. You can attempt to convert 0x00 credentials to 0x01 and set a withdrawal address. You can test partial withdrawals and full withdrawals by exiting your validator."
