Zebra 6.1.0 - 2026-07-17

Added

• Added the getstandardfee RPC, a parameterless method returning the
  recommended standard fee per logical action (the ZIP-317 marginal fee, 5000
  zatoshis) with a version field for future dynamic fee estimation
  (#10717).

Security

• Reserve space for the block header and transaction count when selecting block template
  transactions, so blocks mined from Zebra's templates can no longer exceed the consensus size
  limit (GHSA-95m2-vx53-v2jw).
• Avoid quadratic validation work when checking the remaining transparent value of blocks with
  many transactions (GHSA-4g24-549m-hp75).
• Prevent a peer from stalling chain synchronization by delivering a rejected
  block body that shares its header hash with a later valid block
  (GHSA-8gxx-hc65-vv82).
• Score misbehavior for peers that directly push consensus-invalid transactions, matching the
  treatment of peers that advertise them
  (GHSA-g7c4-2w6c-cr3r).
