-Changes in version 1.3:
+Changes in version 1.4:
-Two incomplete values of expected exit status producing sporadic
-failures of the tests have been fixed.
+The option "--format" has been renamed to "-O, --force-format".
-It has been documented that the "--format" option does not verify the
-format, allowing for example the processing of compress'd (.Z) files
-with gzip.
+Option "-M, --format=<list>" now excludes from automatic search the
+formats not listed in the comma-separated <list>. This change introduces
+a backward incompatibility with previous versions of zutils.
-Minor fixes.
+If the pattern begins with "-", zgrep now prepends "-e" before passing
+it to grep. ('zgrep -- -pattern file' now works as expected).
-The license has been changed to GPL version 2 or later.
+The targets "install-compress", "install-strip-compress",
+"install-info-compress" and "install-man-compress" have been added to
+the Makefile.
