OpenSSH 5.0 released

I was actually more interested in a WHY. i.e. a simple feature list and 
answers to the question 'you have this feature, why is it there? What was 
it intended for? What's its purpose?' `How do you use it' is, if anything, 
secondary. Right now we can't answer that question because we don't know 
what features *exist* unless we read the entire source base, because many 
of them (e.g. subsystems) are pretty much completely undocumented.

This sort of rationale thing is the sort of question for which an answer 
*must* exist (or why was the feature added in the first place?) but which 
generally the only people who know the answers are the people who added 
the features in the first place :(

(but I agree with the lack-of-manpower part. It's just surprising that, 
given the percentage of security problems caused by unknowing misuse of 
security features, someone on a project as security-obsessed as OpenBSD 
hasn't found the time.)
