        - Implement File getc in XS for improved performance.
        - Add workaround for perl bug around EOF method of tied file
          handles.

        - Save EAGAIN errors after every libssh2 channel and session
          call.
        - Extend exit_signal method to return the tree values comming
          back from libssh2_channel_exit_signal.

          usage errors.
        - Add method exit_signal_number that translates the result of

0.59_15  2016-05-03
        - Channel and SFTP READLINE and readline methods were not
          handling correctly undef as the end of line marker
          (i.e. $/=undef).
        - SFTP and Channel BINMODE methods were returning undef
          instead of 1.

        - READLINE was not clearing the error code correctly.

0.59_13  2016-04-26
        - Detect EOF in most cases (cannot be done always due to
          libssh2 limitations) in "readline" and "getc".
        - Clear error before returning from "readline" as it returns
          undef for compatibility with Perl builtin even when no error
          has happened.
        - Several documentation improvements.

0.59_12  2016-04-26
        *** WARNING: backward incompatible change: "READLINE" had an
          undocumented hard coded timeout of 250ms which made the
          method unreliable. That timeout has been removed. If
          desired, the old behaviour can be attained setting
          non-blocking mode or with a global timeout.
        - Add Channel "readline" method.
        - Add Channel "getc" method.
        - Cleanup of the channel tie interface.

        - Add channel method "read2".
        - Do not retry read operations when "libssh2_channel_read_ex"
          returns 0 (bug report by Ferenc Erki).
        - Fix definitions for LIBSSH2_ERROR_NONE,
          LIBSSH2_SESSION_BLOCK_INBOUND and
          LIBSSH2_SESSION_BLOCK_OUTBOUND.
        - Scale timeout values passed between IO::Socket::* (using
          seconds) and libssh2 (using miliseconds).
        - Several documentation improvements.

0.59_10  2016-04-19
        - Don't warn when undef is passed to method "timeout".
        - Add more tests.
        - Several documentation improvements.

0.59_09  2016-04-18
        - Method "read" was not returning errors correctly.
        - Typemaps for 64bit integers were broken
        - Restrict the channel type to "session" in method "channel".
        - The realclean target of the generated Makefile was deleting
          const-c.inc and const-xs.inc which are not generated
          anymore.
        - Several documentation improvements.

0.59_08  2016-04-18
        - Get extended diagnosis messages when $ENV{AUTOMATED_TESTING}
          is set.

        - Add method die_with_error into Net::SSH2::SFTP
        - Several documentation improvements.

0.59_05  2016-04-16
        - Switch the order of "policy" and "known_host_path" arguments
          in method "check_hostkey".
        - Improve "check_hostkey" method adding support for using a
          callback as policy.
        - Rename "remote_port" to "port", "remote_hostname" to
          "hostname" and "check_remote_hostkey" to "check_hostkey".
        - Rewrite constant generation code
        - Several documentation improvements.

0.59_04  2016-04-13

        - Compilation was broken for perls 5.8.0 .. 5.8.3.
        - Several documentation improvements.

0.59_01  2016-04-11
        *** WARNING: this release includes lots of changes, some
            visible, most internal. Regressions are expected. Also,
            it introduces some minor backward incompatible changes -
            but in those cases, the old behavior was broken or insane
            anyway.

        - libssh2 version 1.7.0 is now recommended. The module would
          still compile against older versions, but not all its
          features will be available.
        - Makefile.PL has been refactored and improved. Now it is
          better able to find the library libssh2 and compile code
          using it.
        - Lots of XS code refactoring has been performed in order to
          simplify the module internals. Specifically, now typemaps
          are used extensively to convert between C and Perl
          types. Also, some complex non-performance-critical functions
          have been moved to the Perl side or broken in a high level
          Perl wrapper and a low level simpler C wrapper.
        - KnownHost methods now return undef on error instead of
          die'ing. Note that this submodule is still marked as
          experimental.
        - Die when data containing wide characters is passed
          (i.e. outside the latin1 range). In previous versions,
          methods on this module would happily accept strings
          internally encoded as latin1 or utf8 and pass then along
          untouched, resulting in unreliable behavior.
        - In 32bit perls, return offsets and file sizes as NVs when
          required to avoid overflow.
        - Method "new" now also accepts the options "compress" and
          "sigpipe".
        - Passing options to "connect" is now deprecated.
        - Passing a file descriptor number to "connect" is not
          supported anymore (it was already broken).
        - Method "connect" consistently returns undef on error. The
          error code can be retrieved calling the "error" method
          (requires libssh2 1.7.0). In previous versions, some errors
          made the method die.
        - Timeouts are handled correctly inside "connect".
        - Report EAGAIN in the same way as any other error. This
          introduces a minor backward incompatibility, but the old
          behavior was utterly insane and undocumented, and so
          probably, nobody was using it right anyway!
        - Use libssh2_session_set_last_error function for storage of
          the Perl level errors (required libssh2 1.7.0). This may
          introduce some minor backward incompatibilities, but the old
          code was broken and unreliable anyway.

0.18  2007-11-10  dbr  (svn revision 56)
        - Note version change: synced to libssh2.  Should be compatible with
           libssh2 0.16+, including future versions provided API remains stable.
        - Documented Net::SSH2::version class method.
        - Removed references to LIBSSH2_APINO (removed in libssh2 0.16);
           fixes rt.cpan.org #28722.
        - Fixed memory leak in poll (rt.cpan.org #27368, based on patch
           from David Sullivan).
        - Fixed 0-valued POSIX flag translation bug (based on patch from Joseph
           Galbraith).

0.10  2007-02-24  dbr  (svn revision 52)
        - Net::SSH2::SFTP::realpath fix (Hugues Lafarge).

        - Add missing Net::SSH2::PublicKey object.
        - Use (arbitrary) 8K buffer in scp_get and scp_put methods, rather
           than trying to transfer the whole file at once (rt.cpan.org #20679).
        - Remove 'use Term::ReadKey'; it's already 'require'd in the keyboard
           authentication callback (rt.cpan.org #22786).
        - Provide libssh2 with Perl's allocator callbacks and use Perl_malloc/
           Perl_mfree instead of bare malloc/free (rt.cpan.org #23930).

0.09  2006-09-25  dbr  (svn revision 50)
        - scp_get fixes: mode mask, truncate on create (Stephen Clouse).
        - Fix O_CREATE to O_CREAT in perldoc.

          gets included in the distribution (Danny Thomas).
        - Add Net::SSH2::debug class method to enable debugging output at
          runtime (used to require recompile to enable).
        - Have poll of empty array return 0 early to fix architectures that
