v0.4.26

- loop.create_future() and loop.create_task() now return
  optimized versions of Future and Task, which are much
  faster.  The performance improvements on some benchmarks
  are up to 35% faster.

- create_unix_server() (similarly to asyncio) now doesn't
  clenup the UNIX socket file after server is closed.

- loop.time() forces libuv loop to always update its
  internal time, so uvloop now behaves exactly like
  asyncio.

- In debug mode callback handles now store tracebacks
  to where they were created.

v0.4.25

- New loop.get_exception_handler method
  (will be in asyncio in Python 3.5.2)

- New loop.create_future() method
  (will be in asyncio in Python 3.5.2)

- Bump libuv version: v1.9.0 -> v1.9.1

- Transport.write is faster now, sequential write
  calls can be up to 3x faster.

- Transport.writelines uses zero-copy now.

v0.4.24

- Fixed create_server to bind to ipv6 addresses with
  the TCP_IPV6ONLY flag.

v0.4.23

- Stability improvements

v0.4.22

- sock_sendall & sock_recv are 40-50% faster now;
