Bug Fixes

• Fix circular references in SSL implementation to reduce

• New uvloop.install() helper function.

  Instead of

  import asyncio
  import uvloop
  asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
  

  it is now possible to simply write

  import uvloop
  uvloop.install()
  

  (by @1st1 in a3d8d401)

Bug Fixes

  in asyncio 3.8. This is a significant change that warrants a release
  candidate to make sure it is tested properly.

  See the linked issue for more details.
