Included Changes
EIP-145: Bitwise Shifting Instructions
Adds native bitwise shift operations (SHL, SHR, SAR) to the EVM, reducing gas costs for bit manipulation.
EIP-1014: CREATE2
Introduces a new opcode for deploying contracts at predictable addresses, enabling state channels and other advanced patterns.
EIP-1052: EXTCODEHASH
Adds an opcode to get the hash of a contract's code, useful for verifying contract identity efficiently.
EIP-1283 Removal
The potentially problematic EIP-1283 (SSTORE gas changes) was not included, following Ethereum's lead with Petersburg.
Smooth Activation
The Agharta upgrade activated without issues, demonstrating the ETC community's ability to coordinate complex network upgrades.
