AsyncSSH 1.16.0 released!

[Ron Frederick]

AsyncSSH version 1.16.0 is now available on Github and PyPI, with new features and bug fixes. Here’s a list of changes since 1.15.1:

* Added support for Ed448 host/client keys and certificates and
rewrote Ed25519 support to use the PyCA implementation, reducing
the dependency on libnacl and libsodium to only be needed to
support the chacha20-poly1305 cipher.

* Added support for PKCS#8 format Ed25519 and Ed448 private and
public keys (in addition to the OpenSSH format previously
supported).

* Added support for multiple delimiters in SSHReader's readuntil()
function, causing it to return data as soon as any of the
specified delimiters are matched.

* Added the ability to register custom key handlers in the line
editor which can modify the input line, extending the built-in
editing functionality.

* Added SSHSubprocessProtocol and SSHSubprocessTransport classes
to provide compatibility with asyncio.SubprocessProtocol and
asyncio.SubprocessTransport. Code which is designed to call
BaseEventLoop.subprocess_shell() or BaseEventLoop.subprocess_exec()
can be easily adapted to work against a remote process by calling
SSHClientConnection.create_subprocess().

* Added support for sending keepalive messages when the SSH
connection is idle, with an option to automatically disconnect
the connection if the remote system doesn't respond to these
keepalives.

* Changed AsyncSSH to ignore errors when loading unsupported key
types from the default file locations.

* Changed the reuse_port option to only be available on Python
releases which support it (3.4.4 and later).

* Fixed an issue where MSG_IGNORE packets could sometimes be sent
between MSG_NEWKEYS and MSG_EXT_INFO, which caused some SSH
implementations to fail to properly parse the MSG_EXT_INFO.

* Fixed a couple of errors in the handling of disconnects occurring
prior to authentication completing.

* Renamed "session_encoding" and "session_errors" arguments in
asyncssh.create_server() to "encoding" and "errors", to match
the names used for these arguments in other AsyncSSH APIs. The
old names are still supported for now, but they are marked as
deprecated and will be removed in a future release.
