upcoming release 6.1: old version of some core components

[No at SPAM at mgEDV.net]

hi together,

during testing the 6.1-BETA4 i found only one major thing
i really like to discuss on the list for my understanding.

why are some major parts of the os are not updated to the
current versions (see examples beyond)? code-improvements
and security-/functionality-fixes come to my mind here.

examples given:
zlib (v1.2.2, 10/2004; current 1.2.3, 07/2005)
openssl (v0.9.7e, 10/2004; current 0.9.7i, 10/2005)
openssh (v4.2p1, 01/2005, current 4.3p2 02/2006)

for openssh, the code-freeze of freebsd was before the
release of 4.3, this makes sense, but what about the rest?

br & cu...

ps: just reply 2 the list please...
