======================
from NEWS:

** Changes in behavior

  The -P option is now based on PCRE2 instead of the older PCRE,
  thanks to code contributed by Carlo Arenas.

  The egrep and fgrep commands, which have been deprecated since
  release 2.5.3 (2007), now warn that they are obsolescent and should
  be replaced by grep -E and grep -F.

** Bug fixes

  The -s option no longer suppresses "binary file matches" messages.
  [Bug#51860 introduced in grep 3.5]
