Tags or hashes:

• monad-bft (consensus): tag v0.15.0 (8facc4fae)
• monad (execution): tag v0.15.0 (817a09f64)

Highlights

• MIP-12: Vote pace + block reward activation — updated vote pacing and block reward activation schedule
• One-time DB metadata migration required (monad-mpt --upgrade) — bumps DB schema MONAD007 → MONAD008, initializing secondary timeline metadata for upcoming dual-timeline support
• RPC batch concurrency limit — new server-side cap on concurrent batch requests to prevent resource exhaustion
• eth_simulateV1 gated behind CLI flag — disabled by default; enable with --enable-eth-simulate-v1
• Raptorcast starvation fix — networking message starvation in raptorcast resolved

Notable consensus/protocol changes (→ MINOR)

• [Consensus] MIP-12: Update vote pace and block reward activation
  • Ref: monad-bft PR #3120

Notable RPC/SDK changes

• [RPC] Add batch concurrent limit — server-side cap on concurrent RPC batch requests
  • Ref: monad-bft PR #3128
• [RPC] Remove decompression support from RPC — compressed request bodies no longer accepted
  • Ref: monad-bft PR #3032
• [RPC] Gate eth_simulateV1 behind --enable-eth-simulate-v1 CLI flag (default: off) — returns "Method not supported" unless flag is set
  • Ref: monad-bft PR #3149

Notable robustness changes

• [Consensus] Fix networking message starvation in raptorcast
  • Ref: monad-bft PR #3137
• [Execution] Convert user-facing MONAD_ASSERT to MONAD_ASSERT_THROW — prevents panics on malformed RPC input
  • Ref: monad (execution) PR #2337
• [Execution] Enforce staking syscall ordering — validation now rejects staking syscalls submitted out of order
  • Ref: monad (execution) PR #2320
• [Execution] Fix event payload overflow check — rounds up size before alignment check to prevent assertion failure on large payloads
  • Ref: monad (execution) PR #2194
• [Execution] Fix MONAD007→MONAD008 migration data corruption on nodes with ≥15.8 TB disk — prevents db_offsets overrun and root-offsets ring bound violation during monad-mpt --upgrade
  • Ref: monad (execution) PR #2387
• [Execution] Fix monad-mpt --upgrade crash on legacy databases — fixes integer underflow causing Assertion 'r != MAP_FAILED' on nodes with databases created before num_cnv_chunks was added to the storage pool footer
  • Ref: monad (execution) PR #2353

Notable internal changes

• [Consensus] Raptorcast: Proposer validation per round — raptorcast now owns a ProposerSchedule type for per-round proposer validation, decoupled from MonadState
  • Ref: monad-bft PR #3114
• [Execution] Dual-timeline: add secondary timeline metadata and monad-mpt --upgrade DB migration tool
  • Ref: monad (execution) PR #2212
• [Execution] MPT memory-ordering fix: route version_lower_bound_ reads through acquire accessor to fix data race on reader path
  • Ref: monad (execution) PR #2310
• [Execution] Fix missing cast from monad_eth_revision to evmc_revision
  • Ref: monad (execution) PR #2308
• [Execution] Add --disable-sq-thread-cpu flag to cmd/monad
  • Ref: monad (execution) PR #2333
• [Execution] Remove support for Petersburg and Constantinople forks (Ethereum replay only)
  • Ref: monad (execution) PR #2327, monad (execution) PR #2325
