+** Bug fixes
+
+ When converting timestamps to gzip file format (32-bit unsigned) or
+ to time_t format (system-dependent), gzip now ignores out-of-range
+ values instead of shoehorning them into the destination format,
+ sometimes with undefined behavior. 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]
+
+ 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 -l no longer falsely reports a write error when writing to a pipe.
+ [bug introduced in gzip-1.7]
+
+ Port to Oracle Solaris Studio 12 on x86-64.
+ [bug present since at least gzip-1.2.4]
+
+ When configuring gzip, ./configure DEFS='...-DNO_ASM...' now
+ suppresses assembler again. [bug introduced in gzip-1.3.5]
+
+
+* Noteworthy changes in release 1.7 (2016-03-27) [stable]
+
+** Changes in behavior
+
+ The GZIP environment variable is now obsolescent; gzip now warns if
+ it is used, and rejects attempts to use dangerous options or operands.
+ You can use an alias or script instead.
+
+ Installed programs like 'zgrep' now use the PATH environment variable
+ as usual to find subsidiary programs like 'gzip' and 'grep'.
+ Previously they prepended the installation directory to the PATH,
+ which sometimes caused 'make check' to test the wrong gzip executable.
+ [bug introduced in gzip-1.3.13]
+
+** New features
+
+ gzip now accepts the --synchronous option, which causes it to use
+ fsync and similar primitives to transfer output data to the output
+ file's storage device when the file system supports this. Although
+ this option makes gzip safer in the presence of system crashes, it
+ can make gzip considerably slower.
+
+ gzip now accepts the --rsyncable option. This option is accepted in
+ all modes, but has effect only when compressing: it makes the resulting
+ output more amenable to efficient use of rsync. For example, when a
+ large input file gets a small change, a gzip --rsyncable image of
+ that file will remain largely unchanged, too. Without --rsyncable,
+ even a tiny change in the input could result in a totally different
+ gzip-compressed output file.
