According to ChainCatcher, Aptos node v1.16.3 has been updated and users need to upgrade to the latest version within the next 5 days. This update aims to improve system stability and security and ensure smooth operation of the network.
Updates include the addition of a procedural macro bytecode_spec to define inline specifications for Move bytecode instructions in Rust, and the addition of a runtime environment outside of the VM that can be cached and potentially shared between VM instances.
