+Changes in version 1.8:
+
+A buffer overflow has been fixed in zcat which happened sometimes when
+the '-v, --show-nonprinting' option was used (or indirectly enabled).
+A canary byte has been added to the output buffer to prevent the buffer
+overflow from happening again.
+
+The option '-R, --dereference-recursive', which recursively follows
+symbolic links, has been added to zcat, zgrep, ztest and zupdate.
+
+The option '-r, --recursive' now skips symlinks that are encountered
+recursively.
+
+If no files are given to zcat, zgrep, ztest and zupdate, a recursive
+search will now examine the current working directory.
+
+Recursive directory loops are now detected.
+
+zcat and zgrep now ignore directories given in the command line if
+'--recursive' is not specified, instead of reporting an error.
+
+Extra trailing slashes are now removed from directories given in the
+command line before recursing into them.
+
+zcat and zgrep now show the right error when they can't open an input
+file instead of showing "No such file or directory".
+
+Killed decompressors are now waited for, preventing failure caused by
+too many open pipes.
+
+Test and document that if a file fails to decompress, zcat, zgrep and
+ztest continue processing the rest of the files.
+
+Test and document that if an error happens while recompressing a file,
+zupdate exits immediately without recompressing the rest of the files.
+
+The configure script now accepts appending options to CXXFLAGS using the
+syntax 'CXXFLAGS+=OPTIONS'.
