Release Notes¶

v0.14.0¶

Feature: Rename subscription wait APIs and ensure they also work well with local subscriptions

Feature: Implement a standard API for endpoints to support non-asyncio based implementations (e.g. Trio)
Feature: Improve flexibility of the APIs that allow waiting on subscriptions
Bugfix: Get rid of warnings on shutdown
Bugfix: Repair broken examples and add a CI job to ensure they don’t break again
Performance: Don’t send events to endpoints that aren’t subscribed to the specific event
Performance: Reduce number of socket sends by precombinging length prefix
Performance: Many small performance improvements in various code paths
Performance: Use a faster request id implementation instead of using an uuid

Change IPC backend from multiprocessing to asyncio
Endpoint.broadcast() is now async
Endpoint.broadcast_nowait() now exists, it schedules the message to be broadcast
Endpoint.start_serving_nowait() no longer exists
Endpoint.connect_to_endpoints_blocking() no longer exists
Endpoint.stop() must be called or else some coroutines will be orphaned
Endpoint can only be used from one event loop. It will remember the current event loop when an async method is first called, and throw an exception if another of its async methods is called from a different event loop.
Messages will be compressed if python-snappy is installed
Lahja previously silently dropped some exceptions, they are now propogated up

Performance: Connect endpoints directly without central coordinator (BREAKING CHANGE)
