Tags or hashes:

• monad-bft (consensus): tag v0.15.2 (6373056bf)
• monad (execution): tag v0.15.2 (2422a8592)

Highlights

• MIP-8 gas schedule — adds page-based storage gas schedule; eth_createAccessList deduplicates storage keys by page (activation in a future release)
• Follow-up to MIP-12: Block reward validation — maximum block reward is now validated; blocks exceeding the cap are rejected
• EIP-7843: Consensus round in tx context — Monad consensus round number threaded into evmc_tx_context via BlockHeader::slot_number
• Dual-timeline DB support — MPT database supports a secondary page-encoded timeline; statesync works with both slot- and page-encoded databases

Notable consensus/protocol changes

• [Consensus] Raptorcast: rollout deterministic stage 1 — enroll all nodes to "accept both publish v0". Ref: monad-bft PR #3143
• [Execution] MIP-8: Gas schedule for page-based storage — adds page-based gas schedule (activation in a future release). Ref: monad (execution) PR #2268, monad-bft PR #3150

Notable RPC/SDK changes

• [RPC] eth_createAccessList now deduplicates storage keys by page under MIP-8. Ref: monad (execution) PR #2253
