Changes since 1.6.2:

1. The internal proc 'is_remote' has been renamed to 'isremote' for
   consistency with the other similar procs (eg, istarget). Testsuites
   should use this proc. The 'is_remote' proc is deprecated.
2. runtest now accepts --local_init and --global_init options to override
   the default of reading "site.exp".  See the manual for details.
X. runtest now accepts a --keep_going option to continue with other test
   scripts after a test script invokes an undefined command.
3. A utility procedure relative_filename has been added.  This procedure
   computes a relative file name to a given destination from a given base.
4. The utility procedure 'grep' now accepts a '-n' option that
   includes line numbers in the output, consistent with GNU grep.
5. A new multiplex procedure "testsuite" is added for commands
   retrieving or providing information about the current testsuite.
6. A command "testsuite file" is added to replace the use of the
   "*dir" variables in test scripts.
7. A shell command "dejagnu" is added as a place to hang various
   auxiliary commands not directly involved with running tests. The
   "runtest" command will remain for that purpose for the foreseeable
   future.
8. The first auxiliary command is added: "report card". The "dejagnu
   report card" command reads DejaGnu summary files and produces a
   compact tabular summary across multiple tools.
9. A Tcl namespace is now used for some internal procedures and variables.
   The Tcl namespace ::dejagnu and all child namespaces are entirely
   internal and should not be mentioned in testsuite code.  Its contents
   are subject to change without notice, even on point releases.

Changes since 1.6.1:

1. runtest will abort if $DEJAGNU is defined but the file is not
   found.

Changes since 1.6:

Minor bug fixes, no major changes.

Changes since 1.5.3:

1. Proper support for target communication via SSH has been added.
2. A large number of very old config and baseboard files have been
   removed.  If you need to resurrect these, you can get them from
   version 1.5.3.  If you can show that a board is still in use, it
   can be put back in the distribution.
3. The --status command line option is now the default. This means
   that any error in the testsuite Tcl scripts will cause runtest to
   abort with exit status code 2.  The --status option has been
   removed from the documentation, but will continue to be accepted
   for backward compatibility.
4. runtest now exits with exit code 0 if the testsuite "passed", 1 if
   something unexpected happened (eg, FAIL, XPASS or UNRESOLVED), and
   2 if an exception is raised by the Tcl interpreter.
5. runtest now exits with the standard exit codes of programs that are
   terminated by the SIGINT, SIGTERM and SIGQUIT signals.
6. The user-visible utility procedures `absolute', `psource' and
   `slay' have been removed.  If a testsuite uses any of these
   procedures, a copy of the procedure should be made and placed in
   the lib directory of the testsuite.
7. Support was added for testing the D compiler.
8. ~/.dejagnurc is now loaded last, not first. This allows the user to
   have the ability to override anything in their environment (even
   the site.exp file specified by $DEJAGNU).
9. The user-visible utility procedure `unsetenv' is deprecated and
   will be removed in the next release.  If a testsuite uses any of
   these procedures, a copy of the procedure should be made and placed
   in the lib directory of the testsuite.

Changes since 1.4.4:

1. The runtest.1 man page has been brought up to date.
2. The Docbook/SGML documentation files were removed in favour of the
   Docbook/XML documentation.  The Texinfo source for the Info pages is
   now automatically generated from the Docbook source.
3. The Makefile structure has been substantially simplified.  There
   is now a single top-level Makefile.am.  The use of recursive make
   has been eliminated.
4. lib/mondfe.exp and lib/xsh.exp have been removed.  Users requiring
   these communication modes can still use the DejaGnu 1.4 branch or
   can contact dejagnu@gnu.org to discuss reinstating these files.
5. The configure script now ensures that Expect is installed and that
   it is linked against Tcl 8.3 or greater.
6. The runtest program now gracefully handles the possibility of the
   expect binary vanishing after DejaGnu has been installed (for
   example, by the user altering their PATH).
7. The user-visible utility procedures `absolute', `prune', `psource'
   and `slay' are deprecated and will be removed in the next release.
   If a testsuite uses any of these procedures, a copy of the
   procedure should be made and placed in the lib directory of the
   testsuite.

Changes since 1.4.2:

1. New XML output option, so test results can be loaded into a database.
2. Support for the KFAIL/KPASS (known failures).
3. New "Hello World" example.
4. New tutorial chapter.
5. Test cases build with either GCC 2.x or 3.x.
6. BlueGnu has been removed from the contrib directory.
7. The contrib/test* scipts were bitrotten and have been removed.  If
   you still want copies of these, they can be found in the previous
   DejaGnu release.
8. i960glue.c has been removed.

Changes since 1.4.1:

1. Various patches for bugs reported from net users.
2. Test case builds with either libstdc++-v3 (as used by GCC 3.0.x) or
   the older v2 (as used by GCC 2.95.x).

Changes since 1.4.0:

1. There is new support for a simple unit testing API, that is also
   useful for embedded testing.

Changes since 1.3:

1. DejaGnu is now back under active maintainance. The initial work has
   been rewriting the manual to bring it up to date, and switching to
   SGML.
2. NT support has also been added.
3. DejaGnu now uses Automake.

Changes since 1.1.1:

1. Works with (included in release) Tcl 7.3 and Expect 5.6.
2. Much better error trapping and handling, including the execution of
   sub scripts.
3. Re-worked configuration subsystem.
4. Default handling for testing unknown targets.
5. New testsuite for expect and runtest.
6. More debugging procedures.

Changes since 1.0:

1. DejaGnu now conforms to POSIX 1003.3, a standard for testing frameworks.
2. A Tcl debugger written by Don Libes has been added.
3. Lots of bug fixes.

Changes since 0.9:

1. DejaGnu now installs itself like other utilities.
2. 700 G++ tests are included.
3. The bugs in the GCC tests have been fixed.
4. Testsuites are released separately.
5. Testsuite sources now reside with the within each tool's source tree.
