See the file ChangeLog for the details of all changes.
User visible changes from 1.0.6 to 1.0.7.
o Allow zmore to read from standard input (like more).
o Support the 68000 (Atari ST) in match.S.
o Retry partial writes (required on Linux when gzip is suspended in a pipe).
o Allow full pathnames and renamings in gzexe.
Don't let gzexe compress setuid executables or gzip itself.
o Added vms/Makefile.gcc for gcc on the Vax.
o Allow installation of binaries and shell scripts in different dirs.
o Allows complex PAGER variable in zmore (e.g.: PAGER="col -x | more")
o Allow installation of zcat as gzcat.
o Several small changes for portability to old or weird systems.
o Suppress help message and send compressed data to the terminal when
gzip is invoked without parameters and without redirection.
o Add compile option GNU_STANDARD to respect the GNU coding standards:
with -DGNU_STANDARD, behave as gzip even if invoked under the name gunzip.
(I don't like the last two changes, which were requested by the FSF.)
User visible changes from 1.0.5 to 1.0.6.
o Let gzexe detect executables that are already gzexe'd.
o Keep file attributes in znew and gzexe if cpmod is available.
o Don't try restoring record format on VMS (1.0.5 did not work correctly)
o Added asm version for 68000 in amiga/match.a.
Use asm version for Atari TT and NeXT.
o For OS/2, assume HPFS by default, add flag OS2FAT if necessary.
o Fixed some bugs in zdiff and define zcmp as a link to zdiff.
User visible changes from 1.0.4 to 1.0.5.
o For VMS, restore the file type for variable record format, otherwise
extract in fixed length format (not perfect, but better than
forcing all files to be in stream_LF format).
o For VMS, use "-z" default suffix and accept a version number in file names.
o For Unix, allow compression of files with name ending in 'z'. Use only
.z, .*-z, .tgz, .taz as valid gzip extensions. In the last two cases,
extract to .tar by default.
o On some versions of MSDOS, files with a 3 character extension could not
o Garbage collect files in /tmp created by gzexe.
o Fix the 'OS code' byte in the gzip header.
o For the Amiga, add the missing utime.h and add support for gcc.
User visible changes from 1.0.3 to 1.0.4.
o Added optimized asm version for 68020.
o Add support for the Atari ST.
o Added zforce to rename gzip'ed files with truncated names.
o Do not install with name uncompress (some systems rely on the
absence of any check in the old uncompress).
o Added missing function (fcfree) in msdos/tailor.c
o Let gunzip handle .tgz files, and let gzip skip them.
o Added -d option (decompress) for gzexe and try preserving file permissions.
o Suppress all warnings with -q.
o Use GZIP_OPT for VMS to avoid conflict with program name.
o ... and many other small changes (see ChangeLog)
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
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
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.
