For primefaces bugfix versions you (or. your customer) need a license. So we can't update to a bug fix version. But we already fixing bugs in primeface on our own. If there is a bug which should be fixed in the delivered version of primeface within ivy, let us know (support@ivyteam.ch).
At the moment we have no plans to update to version 6 of primeface in the next future releases. Because we want to keep the incompatibility gap between releases as small as possible.possible.
