- update to 2.13.0:
* Updated testing and coverage to drop Python 3.6 and add Python 3.11.
* Added new "recv_eof" option to not pass an EOF from a channel to a
redirected target, allowing output from multiple SSH sessions to be
sent and mixed with other direct output to that target.
* Added new methods to make it easy to perform forwarding between TCP
ports and UNIX domain sockets.
* Added a workaround for a problem seen on a Huawei SFTP server where
it sends an invalid combination of file attribute flags.
* Fixed an issue with copying files to SFTP servers that don't support
random access I/O.
* Fixed an issue when requesting remote port forwarding on a dynamically
allocated port.
* Fixed an issue where readexactly could block indefinitely when a signal
is delivered in the stream before the requested number of bytes are
available.
* Fixed an interoperability issue with OpenSSH when using SSH certificates
with RSA keys with a SHA-2 signature.
* Fixed an issue with handling "None" in ProxyCommand, GlobalKnownHostsFile,
and UserKnownHostsFile config file options.
