There's a new release of checkstyle available.
http://checkstyle.sourceforge.net/releasenotes.html#Release_8.1

There's some changes to SuppressionCommentFilter which might not work in all cases as it was in Checkstyle 7, for example:
https://github.com/checkstyle/checkstyle/issues/4884
https://github.com/checkstyle/checkstyle/issues/4841

but as we don't use these kind of suppression it should be OK to do such update.
