+libssh2 1.8.0
+
+This release includes the following changes:
+
+ o added a basic dockerised test suite
+ o crypto: add support for the mbedTLS backend
+
+This release includes the following bugfixes:
+
+ o libgcrypt: fixed a NULL pointer dereference on OOM
+ o VMS: can't use %zd for off_t format
+ o VMS: update vms/libssh2_config.h
+ o windows: link with crypt32.lib
+ o libssh2_channel_open: speeling error fixed in channel error message
+ o msvc: fixed 14 compilation warnings
+ o tests: HAVE_NETINET_IN_H was not defined correctly
+ o openssl: add OpenSSL 1.1.0 compatibility
+ o cmake: Add CLEAR_MEMORY option, analogously to that for autoconf
+ o configure: make the --with-* options override the OpenSSL default
+ o libssh2_wait_socket: set err_msg on errors
+ o libssh2_wait_socket: Fix comparison with api_timeout to use milliseconds
+ 
+This release would not have looked like this without help, code, reports and
+advice from friends like these:
+
+  Alexander Lamaison, Antenore Gatta, Brad Harder, Charles Collicutt,

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+
+Implementation notes:
+
+  This is a true OS/400 implementation, not a PASE implementation (for PASE,
+use AIX implementation).
+
+It uses ASCII as internal character set. This has been accomplished using the
+QADRT library and include files, a C and system procedures ASCII wrapper
+library. See IBM QADRT description for more information.
+  This results in libssh2 being an ASCII library: any function string
+argument is taken/returned in ASCII and a C/C++ calling program built around
+QADRT may use libssh2 functions as on any other platform.
+  QADRT does not define ASCII wrappers for all C/system procedures: an
+additional module (os400sys.c) define some more of them, that are used by
+libssh2 and that QADRT left out.
+  Since standard library entry points expect and return ASCII character strings,
+additional procedures are provided for string transcoding (see below). No
+wrappers to standard procedures are provided: however, nested calls to
+transcoding procedures may be used.
+
+Crypto API is provided by the IBM QC3 API library. It supports RSA, but not DSA.
+
+
+  Standard compilation environment does support neither autotools nor make;
+in fact, very few common utilities are available. As a consequence, the
+libssh2_config.h has been coded manually and the compilation scripts are
+a set of shell scripts stored in subdirectory os400.
+
+  The test environment is currently not supported on OS/400.
+
+
+
+Compiling on OS/400:
+
+  These instructions target people who knows about OS/400, compiling, IFS and
+archive extraction. Do not ask questions about these subjects if you're not
+familiar with.
+
+_ As a prerequisite, QADRT development environment must be installed.
+_ Install the libssh2 sources directory in IFS.
+_ Enter shell (QSH)
+_ Change current directory to the libssh2 sources installation directory
+_ Change current directory to os400
+_ Edit file iniscript.sh. You may want to change tunable configuration
+  parameters, like debug info generation, optimisation level, listing option,
+  target library, zlib availability and location, etc.
+_ Copy any file in the current directory to makelog (i.e.:
+  cp initscript.sh makelog): this is intended to create the makelog file with
+  an ASCII CCSID!
+_ Enter the command "sh make.sh > makelog 2>&1'
+_ Examine the makelog file to check for compilation errors.
+
+  Leaving file initscript.sh unchanged, this will produce the following OS/400
+objects:
+_ Library LIBSSH2. All other objects will be stored in this library.
+_ Modules for all libssh2 units.
+_ Binding directory LIBSSH2_A, to be used at calling program link time for
+  statically binding the modules (specify BNDSRVPGM(QADRTTS) when creating a
+  program using LIBSSH2_A. Also give access to the zlib BNDDIR/SRVPGM if
+  libssh2 is compiled with zlib).
+_ Service program LIBSSH2.<soname>, where <soname> is extracted from the
+  src/Makefile.am VERSION variable. To be used at calling program run-time
+  when this program has dynamically bound libssh2 at link time.
+_ Binding directory LIBSSH2. To be used to dynamically bind libssh2 when
+  linking a calling program.
+_ Source file H. It contains all the include members needed to compile a C/C++
+  module using libssh2.
+_ LIBSSH2, SSH2_PKEY, SSH2_SFTP members in file H. These are the C/C++ header
+  files. Original fames have been mangled to fit member name allowed syntax.
+_ Source file LIBSSH2RPG. It contains all the ILE/RPG /INCLUDE members
+  needed to compile an ILE/RPG program calling libssh2 procedures.
+_ LIBSSH2, SSH2_PKEY, SSH2_SFTP members in file LIBSSH2RPG. These are
+  ILE/RPG translations of the corresponding C header files.
+
+
+
+Special programming consideration:
+
+QADRT being used, the following points must be considered:
+_ If static binding is used, service program QADRTTS must be linked too.
+_ Likewise, if libssh2 has been compiled with zlib support, access to the
+  zlib objects must be provided at link time.
+_ The EBCDIC CCSID used by QADRT is 37 by default, NOT THE JOB'S CCSID. If
+  another EBCDIC CCSID is required, it must be set via a locale through a call
+  to setlocale_a (QADRT's setlocale() ASCII wrapper) with category LC_ALL or
+  LC_CTYPE, or by setting environment variable QADRT_ENV_LOCALE to the locale
+  object path before executing the program.
+_ Do not use original source include files unless you know what you are doing.
+  Use the installed members instead (in /QSYS.LIB/LIBSSH2.LIB/H.FILE).
+
+
+
+String transcoding support:
+
+  To help passing arbitrarily encoded string arguments and/or receiving string
+values from/to the libssh2 API, three non-standard additional procedures are
+provided. They use a session pointer and a "string cache" pointer.
+  Each time a string is transcoded, it is cached in the given cache. It is
+the responsibility of the caller to release the cache when its associted strings
+are no longer needed. These procedures and the string cache type are defined
+in a new libssh2_ccsid.h header file.
+  To create a string cache, use:
+
+#include <libssh2_ccsid.h>
+libssh2_string_cache *  cache = NULL;
+
+  To release all strings in a cache, call:
+
+libssh2_release_string_cache(session, &cache);
+
+  The transcoding procedures are:
+
+char * libssh2_from_ccsid(LIBSSH2_SESSION *session,
+                          libssh2_string_cache **cache,
+                          unsigned short ccsid,
+                          const char *string, ssize_t inlen,
+                          size_t *outlen);
+char * libssh2_to_ccsid(LIBSSH2_SESSION *session,
+                        libssh2_string_cache **cache,
+                        unsigned short ccsid,
+                        const char *string, ssize_t inlen,
+                        size_t *outlen);
+
+where:
+    session      is a libssh2 session used for memory allocation.
+    cache        is the address of a string cache.
+    ccsid        is the external (i.e.: non libssh2) coded character set id.
+                 65535 means no conversion and 0 means the current job's CCSID.
+    string       is the string to convert.
+    inlen        is the source string length in bytes: set to -1 if
+                 null-terminated.
+    outlen       if not NULL, is the address of a variable that will receive
+                 the transcoded string length upon return.
+
+  libssh2_from_ccsid() transcodes the string from the given CCSID to libssh2
+internal encoding (UTF-8). It is intended to be used to convert API input
+parameters.
+  libssh2_to_ccsid() transcodes the string from libssh2 internal encoding
+(UTF-8) to the given CCSID. This has been implemented to get standard API
+string results in a program's native encoding.
+
+  Both these functions return a pointer to the null-terminated converted string,
+or NULL if an error occurred. In addition, the variable pointed by outlen
+receives the effective byte length of the (cached) translated string, or -1
+in case of error.
+
+
+
+ILE/RPG support:
+
+  Since 95% of the OS/400 programmers use ILE/RPG exclusively, a definition
+  /INCLUDE member is provided for this language. To include libssh2
+  definitions in an ILE/RPG module, line
+
+     h bnddir('LIBSSH2/LIBSSH2')
+
+must figure in the program header, and line
+
+     d/include libssh2/libssh2rpg,libssh2
+
+in the global data section of the module's source code.
+If required, members ssh2_sftp, ssh2_pkey and ssh2_ccsid may also be included.
+
+For IFS source compilations, include members are located in directory
+/libssh2/include/libssh2rpg and have their original names retained.
+
+ILE/RPG lacks a serious macro preprocessor, thus C macros requiring this
+feature have not been translated. However, function-like C macros have been
+implemented as procedures and therefore supported in ILE/RPG.
