The Arbitrum community has voted to approve the "ArbOS version 11" proposal, which is now pending execution

ChainCatcher message, the Arbitrum community has voted to approve the "ArbOS version 11" proposal, which is currently awaiting execution. The proposal suggests several improvements to Arbitrum, including support for the EVM Shanghai upgrade and the PUSH0 opcode, as well as various bug fixes. These improvements have been audited and are ready for adoption, involving Arbitrum Orbit, Arbitrum One, and Arbitrum Nova (the proposal pertains to the latter two), while the ArbOS upgrade can be seen as a hard fork of Arbitrum.
