Breaking Changes

System Transaction Execution Overhaul

This release fundamentally changes how system transactions (mint, BLS PoP, metadata, validator) are executed. Previously, system transactions ran against a temporary in-memory database separate from the executor's own state, requiring manual state bridging that introduced state overwrite bugs and bypassed EVM revert semantics. Now all system transactions execute directly on the executor's internal state through a unified transact_system_txn code path, identical to user-transaction execution (#288).

Key breaking changes:

• Unified execution path: The special-cased increment_balances / commit_changes methods, the PendingMints accumulator, and the temporary database have all been removed.
• Mint precompile rewired: mint_precompile now modifies the EVM journal directly via EvmInternals::load_account, participating correctly in checkpoint/revert semantics.
• Executor trait changes: ParallelExecutor and Executor traits gain a new transact_system_txn(evm_env, precompiles, tx_env) method.

Gamma Hardfork

This release introduces the Gamma hardfork, extending the Gravity-native hardfork framework established in v1.1.1 (which shipped Alpha and Beta). Gamma adds new hardfork infrastructure and integration test support, configured via genesis config at a specified block number (#292).

Oracle Nonce Type Change

The nonce type for PollResult and OracleSourceState has been changed from u64 to u128 (#278). This is a breaking change for any code that interacts with the oracle relayer state.
