According to Ethereum core developer Tim Beiko's post on X platform summarizing the latest Ethereum core developer execution meeting (ACDE): "The team is working hard to implement the latest CL specification changes and eliminate any bugs. Ben Edgington urged us to release Devnet 12, even if not all teams are ready next week. In addition, it is worth emphasizing the closure of Goerli: once Dencun is launched on Goerli, all client teams and EF developers will stop running Goerli validators 3 months after the Goerli Dencun upgrade or 1 month after the mainnet Dencun upgrade. After the deadline, we will conduct a month of chaos testing on the network, including slashing. Dencun will also be the last upgrade to go live on the testnet. Therefore, in short, if anyone is still using Goerli as a stable testnet, I recommend migrating."
