This release includes the changes required for the upcoming Chicago hardfork that updates gas pricing for selected EVM opcodes and precompiles. These changes improve gas-cost alignment with execution cost and help maintain network stability.
All validators, RPC providers, node operators, and infrastructure partners should upgrade their Bor nodes before the hardfork activation block.
