The Arbitrum community has voted and implemented the "ArbOS 11 version" AIP proposal. This proposal introduces multiple improvements to Arbitrum, including support for EVM Shanghai upgrade and PUSH0 opcode, as well as various bug fixes. These improvements have been reviewed and are available for adoption by platforms such as Arbitrum Orbit Chain, Arbitrum One, and Arbitrum Nova, which are involved in this proposal. The proposal states that the ArbOS upgrade can be considered a hard fork of Arbitrum.
