v0.8.27

Changed

• Adds isUniversalReplication?: boolean option to the discovery service. By default, replication servers will not auto-start topics that are only signaled by other replication servers.
• Adds bannedTopics?: () => string[] option to the discovery service. Banned topics will not be signaled over active discovery, and replication servers will refuse to replicate them.
• Adds @canvas-js/probe-server, which uses a headless Chromium browser to verify that replication servers are online.
• Better metrics and monitoring.
