The Arbitrum community has opened the voting for the "ArbOS Version 11" AIP proposal

ChainCatcher news, the Arbitrum community has opened the "ArbOS 11 version" AIP proposal voting, which will end at 06:11 Beijing time on December 5. The current support rate is 99.8%. This proposal introduces several improvements to Arbitrum, including support for the EVM Shanghai upgrade and the PUSH0 opcode, as well as various bug fixes. These improvements have already been audited and are available for adoption by Arbitrum Orbit chains, Arbitrum One, and Arbitrum Nova, with the proposal concerning the latter two.

The proposal states that the ArbOS upgrade can be considered a hard fork of Arbitrum. Specifically, since the latest version of Geth includes support for the changes made to the EVM in the Shanghai L1 upgrade, Arbitrum also needs to synchronize support to ensure there is no divergence with previous versions of the node software. Currently, the smart contract code for executing the on-chain upgrade has been audited by Trail of Bits. The version of ArbOS currently used by Arbitrum One and Arbitrum Nova is ArbOS 10.
