From the mailing list:

I would like to make a release in the next few days, so here

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."	task	closed	normal	7.6	Book	SVN	normal	fixed
