Zebra 6.3.0 Release
Zebra 6.3.0 is a recommended security release. It fixes four security advisories in block synchronization and peer scoring, including a peer-induced delay in tip discovery, a near-tip sync stall, and gaps allowing malicious peers to get honest peers banned or evade banning. It also hardens inbound ban enforcement, adds a getdeprecationinfo RPC, new DNS seeders, and more granular network metrics. Operators are encouraged to upgrade.
