Changelog:

• ⚠️ Protocol breaking changes (i.e. no interop with previous versions):
  • New protocol version: 0.6
• ⚠️ API breaking changes:
  • zenoh-net API was removed, all its features being now accessible in zenoh API.
  • zenoh API now uses the builder pattern, to allow extensions without breaking backward compatibility.
  • See the migration guide.
• New features:
  • Configuration via a JSON5 (or YAML) file.
  • New unstable feature tagging the API parts that are subject to future changes
  • Add support for multiple peers sub-networks routing modes:
    • linkstate: supports any topology including mesh networks.
    • peer_to_peer: provides greater scalability and better performances.
  • Some configuration values can be modified at runtime:
    • connect/endpoints
  • Add support for user errors and infrastructure errors in query replies (#242).
  • Add support for callback notifications and stream notifications for Queryable, Queries as well as Subscribers.
  • The API allows creation of entities (Subscriber, Queryable, ...) with static lifetime to facilitate multitask programming (#162).
  • New AUTO query consolidation that automatically selects the best consolidation to apply in the current context (#207).
  • The local_routing option is replaced by new (unstable) allow_origin options that can be enabled/disabled for each Subscriber and Queryable individually (#317).
  • Improved scouting configuration.
• Bug fixes:
  • All tasks started by zenoh are now properly terminated at session closure.
  • Fixed bug routing data from peers to clients (#215).
  • Fixed bug in multicast scouting.
  • Fixed deadlock in queries routing.
• Other changes:
  • The "storages" plugin is renamed as "storage_manager" plugin. It's no longer loaded by default at zenohd startup. And its configuration changed (see https://zenoh.io/docs/manual/plugin-storage-manager/).
  • The default reception and transmissions buffer sizes have been lowered to avoid high memory consumption with large number of peers and improve scalability (#209).
