#+TITLE: Guile-SSH News -- history of user-visible changes.
#+STARTUP: content hidestars

Copying and distribution of this file, with or without modification,

notice and this notice are preserved.
* Changes in version 0.5.0 (2014-02-05)
** Implement Guile-SSH channels as GNU Guile ports.
Now channels can be used with regular procedures such as `display',
`write' and `read-line'.
** `session-set!' and `server-set!' now take log-verbosity as a symbol
Use symbols to represent log levels instead of numbers.
** Remove duplicates of some session options
Remove duplicates that are existed for some Guile-SSH session
options: `port-str' (duplicates `port', differs only in expected
type of value), `log-verbosity-str' (duplicates `log-verbosity',
differs only in expected type of value), `add-identity' (duplicates
`identity', no differences).
** New `userauth-autopubkey!' procedure.
The procedure can be used for public key authentication with a SSH
agent.
** New procedures.
`channel-set-stream!', `channel-get-stream', `session?', `server?',
`message?'.
** Remove procedures.
These procedures are removed due to changes in Guile-SSH channel
API: `close-channel!', `channel-poll' `free-channel!',
`channel-read`, `channel-write'.
** Add documentation in Texinfo format
The Guile-SSH reference manual in Info format will be installed on
`make install' into `${prefix}/share/info' directory.
** Update sssh/ssshd example.
*** `examples/sssh.scm' and `examples/ssshd.scm' are updated
to use the new Guile-SSH channel API.
*** `sssh.scm` now uses `userauth-autopubkey!'
*** `ssshd.scm' now parses command-line options
See `ssshd.scm --help'.
** Add echo server/client example.
See `examples/echo' directory.
** Add automated tests.
See `tests/' directory.
* Changes in version 0.4.0 (2013-11-26)
** Port the library to GNU Guile version 2.0
Now the library works with GNU Guile version 2.0 as well as 1.8.
** Remove "ssh:" prefix from procedures names.
If it is needed, an user's prefix can be added by setting a renamer
for a module on loading. See the documentation for the GNU Guile
module system.
** Implement basic SSH server API.
** Fix a memory corruption in `channel-read'
The problem was seen on reading of an output from "lsb_release -a"
command.
** Fix a memory corruption during GC'ing of SSH keys.
** Fix a bug in `session-set!'
Fix the bug that leads to an error if the user tried to set a
correct boolean option.
** New `channel-write' procedure.
** New `channel-request-pty' procedure.
** New `channel-request-shell' procedure.
** New `channel-set-pty-size!' procedure.
** Fix the name of `write-known-host!'
The procedure was called `authenticate-server' by mistake. Rename
it to `write-known-host!'.
** Change error handling in some procedures.
Now `write-known-host!', `channel-open-session',
`channel-request-exec', `channel-request-env', `close-channel!',
throw an exception on error. The return value of these procedures
now is undefined.
** `authenticate-server' now throws guile-ssh-error exception on error.
Don't return the 'error symbol, throw an exception instead.
** `server-set!' now throws guile-ssh-error exception on error.
The return value now is undefined.
** Rename `make-session' to `%make-session'.
See `make-session' below.
** New `make-session' procedure.
This is a convenient wrapper for `%make-session' which allows to
set session options by passing them as keywords.
** Rename `connect' to `connect!'.
** Fix a typo in an option symbol
'strcthostkeycheck -> 'stricthostkeycheck
** Fix an infinite loop in `public-key->string'.
The problem was observed on Ubuntu GNU/Linux 10.04 LTS.
** Add examples to the repository.
See the "examples/" directory.
** Improve printing of SSH keys, channels and messages.
Examples: #<public rsa key>, #<open ssh channel>
* Changes in version 0.3.1 (2013-07-14)
** Use a simpler method to GC'ing of SSH channels.
The idea is that we don't have to free resources allocated by a
channel during its GC'ing, because these resources will be freed
anyway when the related SSH session is GC'ed. However, to be able
to control allocating of resources more precisely, introduce new
procedure ssh:free-channel! that can be used for freeing resources
allocated by a channel.
** ssh:free-channel!
New procedure.
** Make the library thread-safe.
* Changes in version 0.3 (2013-07-13)
** Improve working with public keys.
Because some libssh functions are working with public keys
represented as a ssh_string instead of a ssh_public_key, we try to
hide this peculiarity so all kinds of keys are look like a <key>
class from the Scheme perspective.
** Fix segmentation faults on GC'ing of SSH objects.
The program doesn't crashes anymore during GC'ing of SSH objecs.
** ssh:public-key-from-file
Make it work. Return newly created <key> instance or #f on error.
** ssh:public-key->string
Take a key as a <key> instance.
** ssh:private-key-from-file
Fix call to an undefined procedure. Return #f on error.
** ssh:get-key-type
New procedure. The procedure returns type for a passed <key>
instance. Possible types are: 'dss, 'rsa, 'rsa1, 'unknown
** ssh:userauth-get-list
New procedure. The procedure returns a list of available
authentication methods for a given SSH session
** ssh:channel-read
Fix call to an undefined procedure. Throw guile-ssh-error
exception on error.
** ssh:close-channel!
Fix return value: return #t if channel is closed successfully, #f
otherwise.
** ssh:blocking-flush!
Return 'error by default.
** ssh:session-set!
Fix a bug with uint32 options setting.
** SSH objects now comparable.
* Changes in version 0.2 (2013-05-25)
** Release of the first stable version of Guile-SSH.
