Release 2.12.0 (10 Aug 2022)
----------------------------
* Added top-level functions run_client() and run_server() which allow
you to begin running an SSH client or server on an already-connected
socket. This capability is also available via a new "sock" argument
in the existing connect(), connect_reverse(), get_server_host_key(),
and get_server_auth_methods() functions.
* Added "sock" argument to listen() and listen_reverse() functions
which takes an already-bound listening socket instead of a host
and port to bind a new socket to.
* Added support for forwarding break, signal, and terminal size updates
when redirection of stdin is set up between two SSHProcess instances.
* Added support for sntrup761x25519-sha512@openssh.com post-quantum
key exchange algorithm. For this to be available, the Open Quantum
Safe (liboqs) dynamic library must be installed.
* Added "sig_alg" argument to set a signature algorithm when creating
OpenSSH certificates, allowing a choice between ssh-rsa, rsa-sha2-256,
and rsa-sha2-512 for certificates signed by RSA keys.
* Added new read_parallel() method in SFTPClientFile which allows
parallel reads to be performed from a remote file, delivering
incremental results as these reads complete. Previously, large
reads would automatically be parallelized, but a result was only
returned after all reads completed.
* Added definition of __all__ for public symbols in AsyncSSH to make
pyright autocompletion work better. Thanks go to Nicolas Riebesel
for providing this change.
* Updated SFTP and SCP glob and copy functions to use scandir() instead
of listdir() to improve efficiency.
* Updated default for "ignore_encrypted" client connection option to
ignore encrypted keys specified in an OpenSSH config file when no
passphrase is provided, similar to what was previosuly done for
keys with default names.
* Fixed an issue when using an SSH agent with RSA keys and an X.509
certificate while requesting SHA-2 signatures.
* Fixed an issue with use of expanduser() in unit tests on newer versions
of Python. Thanks go to Georg Sauthoff for providing an initial version
of this fix.
* Fixed an issue with fallback to a Pageant agent not working properly
on Windows when no agent_path or SSH_AUTH_SOCK was set.
* Fixed improper escaping in readuntil(), causing certain punctuation in
separator to not match properly. Thanks go to Github user MazokuMaxy
for reporting this issue.
* Fixed the connection close handler to properly mark channels as fully
closed when the peer unexpected closes the connection, allowing
exceptions to fire if an application continues to try and use
the channel. Thanks go to Taha Jahangir for reporting this issue and
suggesting a possible fix.
* Eliminated unit testing against OpenSSH for tests involving DSA and
RSA keys using SHA-1 signatures, since this support is being dropped
in some distributions of OpenSSH. These tests are still performed, but
using only AsyncSSH code. Thanks go to Ken Dreyer and Georg Sauthoff
for reporting this issue and helping me to reproduce it.
