v0.12.0

New Features

• New SSL implementation. The new implementation is faster and
  and more complete, and might become the default SSL implementation
  in asyncio 3.9.

  See the linked issue for more details.

  (by @fantix in 9cba749 for #158, #176)

• 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 a3d8d40)

Bug Fixes

• All bug fixes from 0.11.0—0.11.3 are included in
  this release.

• ssl.CertificateError is no longer logged as it's delivered to
  the Protocol.connection_lost() anyways.
  (by @fantix in 848e478 for #195, #199)

• Don't use non-existent UDPTransport._address attribute.
  (by @jlaine in f24c2c5 for #207)

Performance

• Improve UDPTransport.sendto() performance.
  (by @jlaine in d5ad2b8 for #214)

Build

• Upgrade Cython 0.28.x -> 0.29.0.

v0.12.0rc1

New Features

• New SSL implementation. The new implementation is faster and
  and more complete, and will become the default SSL implementation
  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.
