The Arbitrum community has voted to approve the proposal for "ArbOS 11 version", which is currently awaiting execution.
BlockBeats News reported on January 8th that the Arbitrum community has voted in favor of the "ArbOS 11 version" proposal, which is currently awaiting execution. The proposal suggests introducing several improvements to Arbitrum, including support for the EVM Shanghai upgrade and PUSH0 opcode, as well as various bug fixes.
These improvements have been audited and are ready to be adopted, involving Arbitrum Orbit, Arbitrum One, and Arbitrum Nova (the proposal involves the latter two), and the ArbOS upgrade can be considered a hard fork of Arbitrum.
