Tags or hashes:

• monad-bft (consensus): tag v0.16.6 (656435c15)
• monad (execution): tag v0.16.6 (4a0c81f54)

Highlights

• Debian packages for the node. A native binary build script and a Debian package build were added, and packages now stamp the submodule commit and resolve the triedb driver via ldd.
  • Ref: monad-bft PR #3277
• Dual Prometheus/OTLP metrics export. The node can now export metrics over both Prometheus and OTLP from a shared configuration.
  • Ref: monad-bft PR #3275
• State sync protocol v3 with page-encoded storage. State sync now negotiates v3 and relays page-encoded storage records (protocol 1.3), with runloop_monad and statesync assuming a page-encoded primary timeline.
  • Ref: monad (execution) PR #2483, monad (execution) PR #2551
• monad-mpt --upgrade and --repair removed. The --upgrade flag together with the MONAD007 migration, and the --repair flag, have been dropped; operators who relied on them should follow the upgrade instructions.
  • Ref: monad (execution) PR #2709

Notable RPC/SDK changes

• [RPC] eth_simulateV1 now returns simulation failures as error values carrying a bespoke simulation error type instead of throwing.
  • Ref: monad (execution) PR #2556, monad (execution) PR #2557

Notable robustness changes

• [Consensus] Legacy transaction signature v values outside the EIP-155 range are now rejected during RLP decoding.
  • Ref: monad (execution) PR #2606
• [Consensus] High-S secp signatures are now rejected at deserialization, and the node commits to an encoding scheme rather than header bytes.
  • Ref: monad-bft PR #3248
• [EVM] An empty typed transaction is now rejected with an error instead of tripping an assertion.
  • Ref: monad (execution) PR #2604
• [EVM] Memory bounds are now checked once per offset stack element.
  • Ref: monad (execution) PR #2667

Notable performance changes

• [EVM] Reusing cached stack storage now establishes the involved lifetimes.
  • Ref: monad (execution) PR #2603
• [EVM] Cached allocations are now given a concrete deleter.
  • Ref: monad (execution) PR #2634

Notable internal changes

• [Consensus] Raptorcast now canonicalizes the depth and reserved fields.
  • Ref: monad-bft PR #3247
• [Node ops] The monad-wireauth per-session buffer limit is raised to 2 MiB.
  • Ref: monad-bft PR #3294
• [Node ops] monad-dataplane now applies global and per-peer UDP pacing.
  • Ref: monad-bft PR #3175
• [Node ops] statesync now aborts when a socket path is too long for sun_path instead of proceeding.
  • Ref: monad (execution) PR #2598
• [Node ops] Backtrace storage is now aligned and frames are preserved on truncation.
  • Ref: monad (execution) PR #2624
• [EVM] Literal-value shifts are emitted as two unaligned loads, and CLZ is emitted without branches or a stack spill and interpreted without branching on its input.
  • Ref: monad (execution) PR #2631, monad (execution) PR #2632, monad (execution) PR #2633
• [EVM] Block-exit stack writes are now independent of heap addresses and avoid store forwarding stalls.
  • Ref: monad (execution) PR #2644, monad (execution) PR #2660
• [EVM] The zkvm gains a guest library with a two-mode CMake build, ZisK and SP1 backend crates, and an execute_block_zkvm runner with an x86 test runner.
  • Ref: monad (execution) PR #2554, monad (execution) PR #2288
