monad (execution) v0.15.0 Changelog

Tag: v0.15.0
Commit: 817a09f64

Highlights

• One-time DB metadata migration required (monad-mpt --upgrade) — bumps DB schema MONAD007 → MONAD008, initializing secondary timeline metadata for upcoming dual-timeline support

Robustness fixes

• Convert user-facing MONAD_ASSERT to MONAD_ASSERT_THROW — prevents panics on malformed RPC input
  • Ref: monad (execution) PR #2337
• Enforce staking syscall ordering — validation now rejects staking syscalls submitted out of order
  • Ref: monad (execution) PR #2320
• Fix event payload overflow check — rounds up size before alignment check to prevent assertion failure on large payloads
  • Ref: monad (execution) PR #2194
• 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
• 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

Internal changes

• Dual-timeline: add secondary timeline metadata and monad-mpt --upgrade DB migration tool
  • Ref: monad (execution) PR #2212
• MPT memory-ordering fix: route version_lower_bound_ reads through acquire accessor to fix data race on reader path
  • Ref: monad (execution) PR #2310
• Fix missing cast from monad_eth_revision to evmc_revision
  • Ref: monad (execution) PR #2308
• Add --disable-sq-thread-cpu flag to cmd/monad
  • Ref: monad (execution) PR #2333
• Remove support for Petersburg and Constantinople forks (Ethereum replay only)
  • Ref: monad (execution) PR #2327, monad (execution) PR #2325
• monad-mpt status output format changed — the line previously showing MPT database has N history, earliest is X latest is Y now reads MPT database has been configured to retain no more than Z versions., with block height on the Latest finalized is <block> line. monad-status has been updated; operators using custom scripts parsing monad-mpt output should update to read Latest finalized is instead of the old latest is pattern.
