Log message:
py-asyncssh: updated to 2.21.0

Release 2.21.0 (2 May 2025)

* Added sparse file support for SFTP, allowing file copying which
  automatically skips over any "holes" in a source file, transferring
  only the data ranges which are actually present.

* Added support for applications to request that session, connection,
  or TUN/TAP requests arriving on an SSHServerConnection be forwarded
  out some other established SSHClientConnection. Callback methods on
  SSHServer which decide how to handle these requests can now return
  an SSHClientConnection to set up this tunneling, instead of having
  to accept the request and implement their own forwarding logic.

* Further hardened the SSH key exchange process to make AsyncSSH
  more strict when accepting messages during key exchange. Thanks
  go to Fabian Bäumer and Marcus Brinkmann for identifying potential
  issues here.

* Added support for the auth_completed callback in SSHServer to
  be either a callable or a coroutine, allowing async operations
  to be performed when user authentication completes successfully,
  prior to accepting session requests.

* Added support for the sftp_factory config argument be either a
  callable or a coroutine, allowing async operations to be performed
  when starting up a new SFTP server session.

* Fixed a bug where the exit() method of SFTPServer didn't handle
  being declared as a coroutine. Thanks go to C. R. Oldham for
  reporting this issue.

* Improved handling of exceptions in connection_lost() callbacks.
  Exceptions in connection_lost() will now be reported in the
  debug log, but other cleanup code in AsyncSSH will continue,
  ignoring those exceptions. Thanks go to Danil Slinchuk for
  reporting this issue.

Log message:
py-asyncssh: updated to 2.20.0

Release 2.20.0 (17 Feb 2025)

* Added support for specifying an explicit path when configuring
  agent forwarding. Thanks go to Aleksandr Ilin for pointing out
  that this options supports more than just a boolean value.

* Added support for environment variable expansion in SSH config,
  for options which support percent expansion.

* Added a new begin_auth callback in SSHClient, reporting the
  username being sent during SSH client authentication. This can be
  useful when the user is conditionally set via an SSH config file.

* Improved strict-kex interoperability during re-keying. Thanks go
  to GitHub user emeryalden for reporting this issue and helping
  to track down the source of the problem.

* Updated SFTP max_requests default to reduce memory usage when
  using large block sizes.

* Updated testing to add Python 3.13 and drop Python 3.7, avoiding
  deprecation warnings from the cryptography package.

* Fixed unit test issues under Windows, allowing unit tests to run
  on Windows on all supported versions of Python.

* Fixed a couple of issues with Python 3.14. Thanks go to Georg
  Sauthoff for initially reporting this.

Log message:
py-asyncssh: updated to 2.19.0

Release 2.19.0 (12 Dec 2024)

* Added support for WebAuthN authentication with U2F security keys,
  allowing non-admin Windows users to use these keys for authentication.
  Previously, authentication with U2F keys worked on Windows, but only
  for admin users.

* Added support for hostname canonicalization, compatible with the
  configuration parameters used in OpenSSH, as well as support for the
  "canonical" and "final" match keywords and negation support for
  match. Thanks go to GitHub user commonism who suggested this and
  provided a proposed implementation for negation.

* Added client and server support for SFTP copy-data extension and
  a new SFTP remote_copy() function which allows data to be moved
  between two remote files without downloading and re-uploading the
  data. Thanks go to Ali Khosravi for suggesting this addition.

* Moved project metadata from setup.py to pyproject.toml. Thanks go to
  Marc Mueller for contributing this.

* Updated SSH connection to keep strong references to outstanding
  tasks, to avoid potential issues with the garbage collector while
  the connection is active. Thanks go to GitHub user Birnendampf for
  pointing out this potential issue and suggesting a simple fix.

* Fixed some issues with block_size argument in SFTP copy functions.
  Thanks go to Krzysztof Kotlenga for finding and reporting these issues.

* Fixed an import error when fido2 package wasn't available. Thanks go
  to GitHub user commonism for reporting this issue.

Log message:
py-asyncssh: updated to 2.18.0

Release 2.18.0 (26 Oct 2024)
----------------------------

* Added support for post-quantum ML-KEM key exchange algorithms,
  interoperable with OpenSSH 9.9.

* Added support for the OpenSSH "limits" extension, allowing the
  client to query server limits such as the maximum supported read
  and write sizes. The client will automatically default to the reported
  maximum size on servers that support this extension.

* Added more ways to specify environment variables via the `env` option.
  Sequences of either 'key=value' strings or (key, value) tuples are now
  supported, in addition to a dict.

* Added support for getting/setting environment variables as byte strings
  on platforms which support it. Previously, only Unicode strings were
  accepted and they were always encoded on the wire using UTF-8.

* Added support for non-TCP sockets (such as a socketpair) as the `sock`
  parameter in connect calls. Thanks go to Christian Wendt for reporting
  this problem and proposing a fix.

* Changed compression to be disabled by default to avoid it becoming a
  performance bottleneck on high-bandwidth connections. This now also
  matches the OpenSSH default.

* Improved speed of parallelized SFTP reads when read-ahead goes beyond
  the end of the file. Thanks go to Maximilian Knespel for reporting
  this issue and providing performance measurements on the code before
  and after the change.

* Improved cancellation handling during SCP transfers.

* Improved support for selecting the currently available security key
  when the application lists multiple keys to try. Thanks go to GitHub
  user zanda8893 for reporting the issue and helping to work out the
  details of the problem.

* Improved handling of reverse DNS failures in host-based authentication.
  Thanks go to GitHub user xBiggs for suggesting this change.

* Improved debug logging of byte strings with non-printable characters.

* Switched to using an executor on GSSAPI calls to avoid blocking the
  event loop.

* Fixed handling of "UserKnownHostsFile none" in config files. This
  previously caused it to use the default known hosts, rather than
  disabling known host checking.

* Fixed a runtime warning about not awaiting a coroutine in unit tests.

* Fixed a unit test failure on Windows when calling abort on a transport.

* Fixed a problem where a "MAC verification failed" error was sometimes
  sent on connection close.

* Fixed SSHClientProcess code to not raise a runtime exception when
  waiting more than once for a process to finish. Thanks go to GitHub
  user starflows for reporting this issue.

* Handled an error when attempting to import older verions of pyOpenSSL.
  Thanks go to Maximilian Knespel for reporting this issue and testing
  the fix.

* Updated simple_server example code to switch from crypt to bcrypt,
  since crypt has been removed in Python 3.13. Thanks go to Colin
  Watson for providing this update.

py-asyncssh: updated to 2.17.0

Release 2.17.0 (2 Sep 2024)

* Add support for specifying a per-connection credential store for GSSAPI
  authentication. Thanks go to GitHub user zarganum for suggesting this
  feature and proposing a detailed design.

* Fixed a regression introduced in AsyncSSH 2.15.0 which could cause
  connections to be closed with an uncaught exception when a session
  on the connection was closed. Thanks go to Wilson Conley for being
  the first to help reproduce this issue, and others who also helped
  to confirm the fix.

* Added a workaround where getaddrinfo() on some systems may return duplicate
  entries, causing bind() to fail when opening a listener. Thanks go to
  Colin Watson for reporting this issue and suggesting a fix.

* Relaxed padding length check on OpenSSH private keys to provide better
  compatibility with keys generated by PuTTYgen.

* Improved documentation on SSHClient and SSHServer classes to explain
  when they are created and their relationship to the SSHClientConnection
  and SSHServerConnection classes.

* Updated examples to use Python 3.7 and made some minor improvements.
