+ gzip -d -S SUFFIX file.SUFFIX would fail for any upper-case byte in SUFFIX.
+ E.g., before, this command would fail:
+ $ :|gzip > kT && gzip -d -S T kT
+ gzip: kT: unknown suffix -- ignored
+ [bug present since the beginning]
+
+ When decompressing data in 'pack' format, gzip no longer mishandles
+ leading zeros in the end-of-block code. [bug introduced in gzip-1.6]
+
+ When converting from system-dependent time_t format to the 32-bit
+ unsigned MTIME format used in gzip files, if a timestamp does not
+ fit gzip now substitutes zero instead of the timestamp's low-order
+ 32 bits, as per Internet RFC 1952. When converting from MTIME to
+ time_t format, if a timestamp does not fit gzip now warns and
+ substitutes the nearest in-range value instead of crashing or
+ silently substituting an implementation-defined value (typically,
+ the timestamp's low-order bits). This affects timestamps before
+ 1970 and after 2106, and timestamps after 2038 on platforms with
+ 32-bit signed time_t. [bug present since the beginning]
+
+ Commands implemented via shell scripts are now more consistent about
+ failure status. For example, 'gunzip --help >/dev/full' now
+ consistently exits with status 1 (error), instead of with status 2
+ (warning) on some platforms. [bug present since the beginning]
+
+ Support for VMS and Amiga has been removed. It was not working anyway,
+ and it reportedly caused file name glitches on MS-Windowsish platforms.

* Noteworthy changes in release 1.8 (2016-04-26) [stable]
** Bug fixes
gzip -d could segfault and/or clobber the stack, possibly leading to
arbitrary code execution. This affects x86_64 but not 32-bit systems.
This fixes CVE-2010-0001.

gzip -d would fail with a CRC error for some valid inputs.
So far, the only valid input known to exhibit this failure was
Major changes in Gzip 1.3.6 (2006-11-20)
-* Fix some race conditions in setting file time stamps, permissions, and owner.
+* Fix some race conditions in setting file timestamps, permissions, and owner.
* Fix some race conditions in signal handling.
* When gzip exits due to a signal, it exits with the signal's status, not 1.
-* gzip now restores file time stamps to the resolution supported by the
+* gzip now restores file timestamps to the resolution supported by the
time-setting primitives of the operating system, typically 1 microsecond.
Formerly it restored them only to the nearest second.
* gzip -r no longer attempts to reset the last-access times of directories
* Added comparison of zip and gzip in the readme file.
* Added small sample programs (ztouch, sub, add)
* Use less memory when compiled with -DSMALL_MEM (for MSDOS).
-* Remove the "off by more than one minute" time stamp kludge
+* Remove the "off by more than one minute" timestamp kludge
Major changes from 1.0.6 to 1.0.7.
* Allow zmore to read from standard input (like more).
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.
+* Preserve timestamp in znew -P (pipe option) if touch -r works.
Major changes from 1.0 to 1.0.1
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.
+* Keep timestamp 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)
