(????-??-??) [?] +** 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 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. + ** Bug fixes gzip -k -v no longer reports that files are replaced.
