| Doc Text: |
Cause:
Previously the behavior of \w and \W symbols in regular expressions were inconsistent with the behavior of [:alnum:] character class.
Consequence:
Some expressions could cause incorrect match/non-match.
Fix:
Upstream fix was backported that makes the behavior consistent.
Result:
Now \w is synonym for [_[:alnum:]] and \W for [^_[:alnum:]].
