Unreleased Changes

vX.X

Special thanks to external contributors on this release:

@p4u from vocdoni.io reported that the mempool might behave incorrectly under a high load. The consequences can range from pauses between blocks to the peers disconnecting from this node. As a temporary remedy (until the mempool package is refactored), the max-batch-bytes was disabled. Transactions will be sent one by one without batching.

Friendly reminder, we have a bug bounty program.
