v0.1.3

Added

• AsyncSSHBackend.over_connection(connection, loop, *, host=None, max_concurrency=None, sftp_version=4, timeout=60.0) builds a backend
  that runs SFTP over an asyncssh.SSHClientConnection your program already
  opened and authenticated, on the event loop that connection is bound to,
  instead of connecting and logging in a second time. Paths and the sftp:
  scheme work on it unchanged. The connection stays yours: close() closes
  only the backend's SFTP channel, and once the connection is closed every
  request raises ConnectionResetError. Keep loop running while the
  backend is used (a request on a stopped loop raises RuntimeError), and
  build a new backend after fork(). Such a backend cannot be pickled.
