this is to ensure, that we do not regress next time when we release next version
from master. So its important to ensure that the fix has been applied to master
sometimes you can assert that the fix has gone into new version of a package
that is due to be uprevved in master and will be done soonish. Such information
is helpful when making security patches for release branches.

Actually there was a suggestion at OEDEM on informing CVE ml that we have
as the CVE fixes get applied to metadata. Thats a good suggestion to have
implemented.
