Hello Guilers!

I'm pleased to announce Guile-SSH 0.17.0:
  https://github.com/artyom-poptsov/guile-ssh/releases/tag/v0.17.0

This release fixes an error in the order of reading configuration
options in "make-session": now config is being read first and then the
options passed as keyword arguments are applied effectively overwriting
the options from the configuration file.

As usual, this release tag is signed with my GPG key[1].


* What is Guile-SSH?

Guile-SSH is a library that provides access to the SSH protocol[3] for
programs written in GNU Guile interpreter.  It is built upon the
libssh[4] library.

Currently Guile-SSH provides the following features:
  - The API that is sufficient for building of standalone SSH clients and
    servers, or for embedding client/server functionality in your lispy Scheme
    applications.
  - Several authentication methods are supported, including password
    authentication, public key and SSH agent authentication methods.
  - Key management procedures: you can make key pairs, read keys from files,
    get key hashes, get public keys from private keys etc.  DSS, RSA, RSA1 and
    ECDSA (by means of OpenSSL) are supported.
  - Port forwarding procedures and high-level API for creating of SSH tunnels.
  - Distributed forms ('dist-map', 'distribute', ...) that allow to spread the
    evaluation of Scheme code between remote hosts.  Or you can just connect
    to a remote REPL from Scheme using 'with-ssh' procedure and evaluate some
    expressions.  No special server needed on the remote side, just an SSH
    daemon and GNU Guile installed!
  - SFTP client API allows you to read and write remote files, or do directory
    traversal over the SSH protocol right from the Scheme code.
  - Remote popen API that allows you to make either input, output or
    bidirectional pipes to remote processes.
  - Detailed documentation in Texinfo format with examples included, even more
    examples in 'examples' directory.
  - Procedures for interaction with SSH agents.


* The list of user-visible changes

Here's the list of user-visible changes (an excerpt from NEWS file):

--8<---------------cut here---------------start------------->8---
* Changes in version 0.17.0 (2024-05-01)
** =make-session= now loads config file before setting options
=make-session= would always overwrite the explicitly set options passed by
keywords with the values from the SSH configuration file.  That lead to
unexpected behavior.

This patch fixes this error.

Reported by graywolf in
<https://github.com/artyom-poptsov/guile-ssh/issues/38>
** =session-set!= now allows to set =rsa-min-size=
Only available if Guile-SSH is compiled with libssh 0.10.
** Add new tests.
** Update the documentation.

Many thanks to all the people who helped me with bug reports, pull

"THANKS" files -- please let me know if I forgot to thank someone or
