NEWS:

** Changes in behavior

  The GREP_OPTIONS environment variable no longer affects grep's behavior.
  The variable was declared obsolescent in grep 2.21 (2014), and since
  then any use had caused grep to issue a diagnostic.

** Bug fixes

  grep's DFA matcher performed an invalid regex transformation
  that would convert an ERE like a+a+a+ to a+a+, which would make
  grep a+a+a+ mistakenly match "aa".
  [Bug#44351 introduced in grep 3.2]

  grep -P now reports the troublesome input filename upon PCRE execution
  failure.  Before, searching many files for something rare might fail with
  just "exceeded PCRE's backtracking limit".  Now, it also reports which file
  triggered the failure.
