Maintenance Release

Note: The release binaries above include a new version of the dvid web console, which requires a slight tweak to your .toml file. Please add the following line to the [server] section:

[server]
webDefaultFile = "index.html"

Changes:

• Minimum mutation ID on startup can be specified in the TOML
• Allow deletion of key classes and versions
• Permit mirroring of all data instances
• Added flatten-mutations command
• Logging improvements
• Kafka enhancements:
  • Kafka activity topic is exposed in /api/server/info
  • Kafka topic suffixes are configurable for each data-instance
  • Allow kafka topic prefix configuration for mutation logging
  • Add annotation sync data to kafka logging
• Enhancements to /split-supervoxel
  • Clients can manually specify split/remain labels for /split-supervoxel (dangerous: power-users only)
  • Permit "empty" and "complete" supervoxel splits (previously, these were considered errors)
• Performance enhancements:
  • Point-queries (i.e. /labels) on labelmap instances can read directly from the compressed blocks (big speedup, especially for annotation syncs)
  • Reduce impact of /mappings request on concurrent mutations
