Current Version: 1.0.3
See the file ChangeLog for the details of all changes.
User visible changes from 1.0.2 to 1.0.3
o Added -K option for znew to keep old .Z files if smaller
o Added -q option (quiet) to cancel -v in GZIP env variable.
o Made gzexe safer on systems with filename limitation to 14 chars.
o Fixed bugs in handling of GZIP env variable and incorrect free with Turbo C.
User visible changes from 1.0.1 to 1.0.2
o Added env variable GZIP for default options. Example:
for sh: GZIP="-8 -v"; export GZIP
for csh: setenv GZIP "-8 -v"
o Added support for the Amiga.
O znew now keeps the old .Z if it is smaller than the .z file.
This can happen for some large and very redundant files.
o Do not complain about trailing garbage for record oriented IO (Vax/VMS).
This implies however that multi-part gzip files are not supported
on such systems.
o Added gzexe to compress rarely used executables.
o Reduce memory usage (required for MSDOS and useful on all systems).
o Preserve time stamp in znew -P (pipe option) if touch -r works.
User visible changes from 1.0 to 1.0.1
o fix trivial errors in the Borland makefile (msdos/Makefile.bor)
User visible changes from 0.8.2 to 1.0
o gzip now runs on Vax/VMS
o gzip will not not overwrite files without -f when using /bin/sh in
background.
o Support the test option -t for compressed (.Z) files.
Allow some data recovery for bad .Z files.
o Added makefiles for MSDOS (Only tested for MSC, not Borland).
o still more changes to configure for several systems
User visible changes from 0.8.1 to 0.8.2:
o yet more changes to configure for Linux and other systems
o Allow zcat on a file with multiple links.
User visible changes from 0.8 to 0.8.1:
o znew has now a pipe option -P to reduce the disk space requirements,
but this option does not preserve timestamps.
o Fixed some #if directives for compilation with TurboC.
User visible changes from 0.7 to 0.8:
o gzip can now extract .z files created by 'pack'.
o configure should no longer believe that every machine is a 386
o Fix the entry for /etc/magic in INSTALL.
o Add patch for GNU tar 1.11.1 and a pointer to crypt++.el
o Uncompress files with multiple links only with -f.
o Fix for uncompress of .Z files on 16-bit machines
o Create a correct output name for file names of exactly N-1 chars when
the system has a limit of N chars.
User visible changes from 0.6 to 0.7:
o Use "make check" instead of "make test".
o Keep time stamp and pass options to gzip in znew.
o Do not create .z.z files with gzip -r.
o Allow again gunzip .zip files (was working in 0.5)
o Allow again compilation with TurboC 2.0 (was working in 0.4)
User visible changes form 0.5 to 0.6:
o gunzip reported an error when extracting certain .z files. The .z files
produced by gzip 0.5 are correct and can be read by gunzip 0.6.
o gunzip now supports multiple compressed members within a single .z file.
o Fix the check for i386 in configure.
o Added "make test" to check for compiler bugs. (gcc -finline-functions
is broken at least on the NeXT.)
o Use environment variable PAGER in zmore if it is defined.
o Accept gzcat in addition to zcat for people having /usr/bin before
/usr/local/bin in their path.
