----------------------+------------------------
We may or may not get this in before the package freeze. It depends on
when 2.17 actualy gets released. Most changes have to do with multi-byte
characters.
From the mailing list:
I would like to make a release in the next few days, so here
is a snapshot of the latest. Please give it a spin.

NEWS:
-------------------------------------------------------
** Improvements
grep -i in a multibyte locale is now typically 10 times faster
for patterns that do not contain \ or [.
grep (without -i) in a multibyte locale is now up to 7 times faster
when processing many matched lines.
Range expressions in unibyte locales now ordinarily use the rational
range interpretation, in which [a-z] matches only lower-case ASCII
letters regardless of locale, and similarly for other ranges. (This
was already true for multibyte locales.) Portable programs should
continue to specify the C locale when using range expressions, since
these expressions have unspecified behavior in non-GNU systems and
are not yet guaranteed to use the rational range interpretation even
in GNU systems.
** Maintenance
grep's --mmap option was disabled in March of 2010, and began to
elicit a warning in January of 2012. Now it is completely gone.
