In this version there is an important bugfix related to IP tunnels and PV resources. The bug has been introduced with release 6.0.0 and therefore all previous releases are not affected. Due to a uninitialized variable the TTL used for the IP tunnels and PV had an undefined value, the result is that packets could be discarded along the way with TTL expired depending on the value actually present and the number of hops.

Since the TTL value was not predictable, also the effect may be visible or not. Release 6.0.4 fixes this problem.
