This latest release fixes two issues encountered over the last few days.
- Improves block sync, specifically plausible block handling. More details here: helium/blockchain-core#1115
- Reduces Reliable Broadcast (RBC) proposal size to 1MB (from 5MB). This is a tradeoff that only permits smaller blocks to be proposed (with fewer transactions). More details here: helium/erlang-hbbft#75
