-* Unreleased
+* Changes in version 0.7.2 (2015-02-24)
+** Remove dependency on libgcrypt added by a mistake
+** Fix "double free or corruption" error on GC'ing of keys
+   Fix "double free or corruption" error that occures in case when a key was
+   derived from an authentication message by means of `message-get-req'.  When
+   such a key is GC'ed then GC'ing of its parent message leads to error, or
+   vice versa.
+** Fix a bug in the channel implementation
+   The bug could occasionally manifest itself on channel reading as the
+   following error:
+#+BEGIN_EXAMPLE
+guile: ports.c:1476: scm_i_fill_input: Assertion `pt->read_pos == pt->read_end' failed.
+#+END_EXAMPLE
+** New `server-get' procedure in (ssh server)
+   The procedure can be used to retrieve server options.
+** New `channel-get-exit-status' procedure in (ssh channel)
+   The procedure allows to get exit status of an executed command from a
+   channel.
+** New `channel-request-send-exit-status' procedure in (ssh channel)
+   The procedure can be used to send the exit status to a client.
+** Improve printing of Guile-SSH server objects
+   Print the bind address of a server object and its bind port.  Example:
+#+BEGIN_EXAMPLE
+#<server 127.0.0.1:12345 9b70ff0>
+#+END_EXAMPLE
+** Update examples
+*** sssh
+    - Check exit status of an executed command.
+*** ssshd
+    - Send exit status to the client according to the result of command
+      execution.
+*** echo server and client
+    - Some cosmetic changes aimed to make the code cleaner.
+** Update documentation
+   - Add description of the new procedures.
+   - Update examples.
+
+* Changes in version 0.7.1 (2014-10-11)
+** New `%get-libssh-version' procedure in (ssh version)
+   The procedure can be used to get libssh version in the "raw" format such
+   as: "0.6.3/openssl/zlib".
+** New `get-crypto-library' procedure in (ssh version)
+   The procedure returns name of a cryptographic library with which libssh was
+   compiled.
+** New `zlib-support?' procedure in (ssh version)
+   The procedure checks if zlib support is enabled in libssh.
+** New `set-log-verbosity!' procedure in (ssh log)
+   The procedure sets global libssh log verbosity.
+** New `get-log-verbosity' procedure in (ssh log)
+   The procedure gets global libssh log verbosity.
+** New `make-keypair' procedure in (ssh key)
+   The procedure can be used to generate a new keypair with the specified
+   parameters.
+** New `private-key-to-file' procedure in (ssh key)
+   The procedure can be used to export a private key to a file (doesn't work
+   if libssh 0.6.3 is compiled with GCrypt).
+** Changes in tests
+*** Fix "end of file" errors in tests
+   Fix the following kind of errors in tests:
+#+BEGIN_EXAMPLE
+ERROR: In procedure scm_i_lreadparen: /path/to/guile-ssh/sources/tests/./client-server.scm:272:34: end of file
+#+END_EXAMPLE
+   Thanks to Ludovic Courtès for reporting the issue and for a good advice how
+   to fix that.
+*** Don't perform ECDSA key tests if libssh is compiled with GCrypt
+    libssh 0.6.3 does not support ECDSA keys if compiled with GCrypt instead
+    of OpenSSL.  Thus, ECDSA key tests used to fail.  Now there is a check
+    that prevents these tests from execution in case when libssh 0.6.3 is
+    compiled with GCrypt.
+** Update documentation
+   - Add description of the new procedures.
+   - Add note about ECDSA keys support with GCrypt library.

 *** Add tests for Guile-SSH keys
 *** Add tests for `authenticate-server' procedure
 ** Bug fixes
+*** Fix a GC issue
+    Keep a reference to the parent session in channels and messages to prevent
+    the session from premature GC'ing.  Without that GC could free a session
+    even if there are live channels and by that break the channels.
 *** `public-key?' and `private-key?' now produce correct result
     Functions now return `#f' if the given argument is not a Guile-SSH
     key object.
