v4.0.1

Compare Source

==================

• Fix regression:

  1. Don't raise TimeoutError from timeout object that doesn't enter into async context
     manager

  2. Use call_soon() for raising TimeoutError if deadline is reached on entering into
     async context manager

  (#​258)

• Make Timeout class available in __all__.

v4.0.0

Compare Source

==================

• Implemented timeout_at(deadline) (#​117)

• Supported timeout.deadline and timeout.expired properties.

• Dropped timeout.remaining property: it can be calculated as
  timeout.deadline - loop.time()

• Dropped timeout.timeout property that returns a relative timeout based on the
  timeout object creation time; the absolute timeout.deadline should be used
  instead.

• Added the deadline modification methods: timeout.reject(),
  timeout.shift(delay), timeout.update(deadline).

• Deprecated synchronous context manager usage
