- Current Version: 1.2.4.
- See the file ChangeLog for the details of all changes.
-
- Major changes from 1.2.3 to 1.2.4
- * By default, do not restore file name and timestamp from those saved
- inside the .gz file (behave as 'compress'). Added the --name option
- to force name and timestamp restoration.
- * Accept - as synonym for stdin.
- * Use manlinks=so or ln to support either hard links or .so in man pages
- * Accept foo.gz~ in zdiff.
- * Added support for Windows NT
- * Handle ENAMETOOLONG for strict Posix systems
- * Use --recursive instead of --recurse to comply with Webster and
- the GNU stdandard.
- * Allow installation of shell scripts with a g prefix: make G=g install
- * Install by default zcat as gzcat if gzcat already exists in path.
- * Let zmore behave as more when invoked without parameters (give help)
- * Let gzip --list reject files not in gzip format even with --force.
- * Don't complain about non gzip files for options -rt or -rl.
- * Added advice in INSTALL for several systems.
-
- Major changes from 1.2.2 to 1.2.3
- * Don't display the output name when decompressing except with --verbose.
- * Remove usage of alloca in getopt.c and all makefiles.
- * Added the zfile shell script in subdirectory sample.
- * Moved the list of compiler bugs from README to INSTALL.
- * Added vms/Readme.vms.
-
- Major changes from 1.2.1 to 1.2.2
- * Fix a compilation error on Sun with cc (worked with gcc).
-
- Major changes from 1.2 to 1.2.1
- * Let zmore act as more if the data is not gzipped.
- * made gzexe more secure (don't rely on PATH).
- * By default, display output name only when the name was actually truncated.
-
- Major changes from 1.1.2 to 1.2
- * Added the --list option to display the file characteristics.
- * Added the --no-name option: do not save or restore original filename
- Save the original name by default.
- * Allow gunzip --suffix "" to attempt decompression on any file
- regardless of its extension if an original name is present.
- * Add support for the SCO compress -H format.
- * gzip --fast now compresses faster (speed close to that of compress)
- with degraded compression ratio (but still better than compress).
- Default level changed to -6 (acts exactly as previous level -5) to
- be a better indication of its placement in the speed/ratio range.
- * Use smart name truncation: 123456789012.c -> 123456789.c.gz
- instead of 12345678901.gz
- * With --force, let zcat pass non gzip'ed data unchanged (zcat == cat)
- * Added the zgrep shell script.
- * Made sub.c useful for 16 bit sound, 24 bit images, etc..
- * Supress warnings about suffix for gunzip -r, except with --verbose.
- * On MSDOS, use .gz extension when possible (files without extension)
- * Moved the sample programs to a subdirectory sample.
- * Added a "Special targets" section in INSTALL.
-

- * Allow suffix other than .gz in znew.
- * Do not display compression ratio when decompressing stdin.

-
- Major changes from 1.0.7 to 1.1.
- * Use .gz suffix by default, add --suffix option.

- * Quit when reading garbage from stdin instead of reporting an error.
- * Added makefile for VAX/MMS and support for wildcards on VMS.
- * Added support for MSC under OS/2.
- * Added support for Prime/PRIMOS.
- * Display compression ratio also when decompressing (with --verbose).

- * Allow installation of binaries and shell scripts in different dirs.
- * Allows complex PAGER variable in zmore (e.g.: PAGER="col -x | more")
- * Allow installation of zcat as gzcat.
- * Several small changes for portability to old or weird systems.
- * Suppress help message and send compressed data to the terminal when
- gzip is invoked without parameters and without redirection.
- * 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.)
-
- Major changes from 1.0.5 to 1.0.6.
- * Let gzexe detect executables that are already gzexe'd.
- * Keep file attributes in znew and gzexe if cpmod is available.
- * Don't try restoring record format on VMS (1.0.5 did not work correctly)
- * Added asm version for 68000 in amiga/match.a.
- Use asm version for Atari TT and NeXT.
- * For OS/2, assume HPFS by default, add flag OS2FAT if necessary.
- * Fixed some bugs in zdiff and define zcmp as a link to zdiff.
-
-
- Major changes from 1.0.4 to 1.0.5.
- * 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).
- * For VMS, use "-z" default suffix and accept a version number in file names.
- * 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.
- * On some versions of MSDOS, files with a 3 character extension could not
- be compressed.
- * Garbage collect files in /tmp created by gzexe.
- * Fix the 'OS code' byte in the gzip header.
- * For the Amiga, add the missing utime.h and add support for gcc.
-
-
- Major changes from 1.0.3 to 1.0.4.
- * Added optimized asm version for 68020.
- * Add support for DJGPP.
-
- * Add support for the Atari ST.
- * Added zforce to rename gzip'ed files with truncated names.
- * Do not install with name uncompress (some systems rely on the
- absence of any check in the old uncompress).
- * Added missing function (fcfree) in msdos/tailor.c
- * Let gunzip handle .tgz files, and let gzip skip them.
- * Added -d option (decompress) for gzexe and try preserving file permissions.
- * Suppress all warnings with -q.
- * Use GZIP_OPT for VMS to avoid conflict with program name.
- * ... and many other small changes (see ChangeLog)
-
-
- Major changes from 1.0.2 to 1.0.3
- * Added -K option for znew to keep old .Z files if smaller
- * Added -q option (quiet) to cancel -v in GZIP env variable.
- * Made gzexe safer on systems with filename limitation to 14 chars.
- * Fixed bugs in handling of GZIP env variable and incorrect free with Turbo C.
-
-
- Major changes from 1.0.1 to 1.0.2
- * Added env variable GZIP for default options. Example:
- for sh: GZIP="-8 -v"; export GZIP
- for csh: setenv GZIP "-8 -v"
- * Added support for the Amiga.
- * znew now keeps the old .Z if it is smaller than the .z file.
- This can happen for some large and very redundant files.
- * 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.
- * Added gzexe to compress rarely used executables.
- * Reduce memory usage (required for MSDOS and useful on all systems).
- * Preserve time stamp in znew -P (pipe option) if touch -r works.
-
-
- Major changes from 1.0 to 1.0.1
- * fix trivial errors in the Borland makefile (msdos/Makefile.bor)
-
-
- Major changes from 0.8.2 to 1.0
- * gzip now runs on Vax/VMS
- * gzip will not not overwrite files without -f when using /bin/sh in
- background.
- * Support the test option -t for compressed (.Z) files.
- Allow some data recovery for bad .Z files.
- * Added makefiles for MSDOS (Only tested for MSC, not Borland).
- * still more changes to configure for several systems
-
-
- Major changes from 0.8.1 to 0.8.2:
- * yet more changes to configure for Linux and other systems
- * Allow zcat on a file with multiple links.
-
-
- Major changes from 0.8 to 0.8.1:
- * znew has now a pipe option -P to reduce the disk space requirements,
- but this option does not preserve timestamps.
- * Fixed some #if directives for compilation with TurboC.
-
-
- Major changes from 0.7 to 0.8:
- * gzip can now extract .z files created by 'pack'.
- * configure should no longer believe that every machine is a 386
- * Fix the entry for /etc/magic in INSTALL.
- * Add patch for GNU tar 1.11.1 and a pointer to crypt++.el
- * Uncompress files with multiple links only with -f.
- * Fix for uncompress of .Z files on 16-bit machines
- * Create a correct output name for file names of exactly N-1 chars when
- the system has a limit of N chars.
-
-
- Major changes from 0.6 to 0.7:
- * Use "make check" instead of "make test".
- * Keep time stamp and pass options to gzip in znew.
- * Do not create .z.z files with gzip -r.
- * Allow again gunzip .zip files (was working in 0.5)
- * Allow again compilation with TurboC 2.0 (was working in 0.4)
-
-
- Major changes form 0.5 to 0.6:
- * 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.
- * gunzip now supports multiple compressed members within a single .z file.
- * Fix the check for i386 in configure.
- * Added "make test" to check for compiler bugs. (gcc -finline-functions
- is broken at least on the NeXT.)
- * Use environment variable PAGER in zmore if it is defined.
- * Accept gzcat in addition to zcat for people having /usr/bin before
- /usr/local/bin in their path.
