I'm going to release gzip-1.6 very soon.
If anyone has suggestions/request for inclusion, speak up quickly.
NEWS currently looks like this:
** New features
gzip now accepts the --keep (-k) option, for consistency with tools
like xz, lzip and bzip2. With this option, gzip no longer removes
named input files when compressing or decompressing.
** Bug fixes
gzip -d no longer malfunctions with certain invalid data in 'pack' format.
[bug introduced in gzip-0.8]
When overwriting, gzip no longer acts as if you typed "y" when you type "n",
on some platforms when compiled with optimization.
[bug introduced in gzip-1.3.6]
zgrep no longer malfunctions with a multi-digit context option like -15.
Now, it passes that option to grep (equivalent to -C15) just as it does
for single-digit options. [bug introduced in gzip-1.3.12]
zmore now acts more like 'more', and is more portable to POSIXish hosts.
