Bump version 0.4.3 → 0.5.0

New features

• asyncio and Trio support through AnyIO

Breaking changes

• WebSocketSession and AsyncWebSocketSession are now context managers. If you were using them directly instead of relying on connect_ws and aconnect_ws, you'll have to adapt your code accordingly:

with WebSocketSession(...) as session:
    ...

async with AsyncWebSocketSession(...) as session:
    ...

• AsyncWebSocketSession.receive_* methods may now raise TimeoutError instead of asyncio.TimeoutError:

Before

try:
    event = await ws.receive(timeout=2.)
except asyncio.TimeoutError:
    print("No event received.")
except WebSocketDisconnect:
    print("Connection closed")

After

try:
    event = await ws.receive(timeout=2.)
except TimeoutError:
    print("No event received.")
except WebSocketDisconnect:
    print("Connection closed")
