Security issues fixed with this release:

CVE-2012-5667
CVE-2015-1345

Fixed bugs:

* Prior to this update, the \w and \W symbols were inconsistently matched to the
[:alnum:] character class. Consequently, regular expressions that used \w and \W
in some cases had incorrect results. An upstream patch which fixes the matching
problem has been applied to fix this bug.
* Previously, the "--fixed-regexp" command-line option was not included in the
grep(1) manual page. Consequently, the manual page was inconsistent with the
built-in help of the grep utility. To fix this bug, grep(1) has been updated to
include a note informing the user that "--fixed-regexp" is an obsolete option.
* Previously, the Perl Compatible Regular Expression (PCRE) library did not work
correctly when matching non-UTF-8 text in UTF-8 mode. Consequently, an error
message about invalid UTF-8 byte sequence characters was returned. To fix this
bug, patches from upstream have been applied to the PCRE library and the grep
utility.
