Release 2.4.2
Fixed a potential race condition when receiving EOF right after a channel is opened.
Fixed a couple of issues related to the error_handler and progress_handler callbacks in AsyncSSH SFTP/SCP.
Fixed a couple of issues related to using pathlib objects with AsyncSSH SCP.
Release 2.4.1
Fixed SCP server to send back an exit status when closing the SSH channel, since the OpenSSH scp client returns this status to the shell which executed it.
Fixed listeners created by forward_local_port(), forward_local_path(), and forward_socks() to automatically close when the SSH connection closes, unblocking any wait_closed() calls which are in progress.
Fixed a potential exception that could trigger when the SSH connection is closed while authentication is in progress.
Fixed tunnel connect code to properly clean up an implicitly created tunnel when a failure occurs in trying to open a connection over that tunnel.
Release 2.4.0
Added support for accessing keys through a PKCS#11 provider, allowing keys on PIV security tokens to be used directly by AsyncSSH without the need to run an SSH agent. X.509 certificates can also be retrieved from the security token and used with SSH servers which support that.
Added support for using Ed25519 and Ed448 keys in X.509 certificates, and the corresponding SSH certificate and signature algorithms. Certificates can use these keys as either subject keys or signing keys, and certificates can be generated by either AsyncSSH or by OpenSSL version 1.1.1 or later.
Added support for feed_data() and feed_eof() methods in SSHReader, mirroring methods of the same name in asyncio’s StreamReader to improve interoperability between the two APIs.
Updated unit tests to test interoperability with OpenSSL 1.1.1 when reading and writing Ed25519 and Ed448 public and private key files. Previously, due to lack of support in OpenSSL, AsyncSSH could only test against OpenSSH, and only in OpenSSH key formats. With OpenSSL 1.1.1, testing is now also done using PKCS#8 format.
Fixed config file parser to properly ignore all comment lines, even if the lines contain unbalanced quotes.
Removed a note about the lack of a timeout parameter in the AsyncSSH connect() method, now that it supports a login_timeout argument.
