I thought we were trying to move to a 'release early, release often' policy.

My experience is that unless one has the full suite of platforms (and who
testing on just ones favourite development platform isn't enough. There are
too many compiler idiosyncrasies.

Personally I would do this, if no other reason to encourage users to

Should we not be saying "If you are more than n (=2?) releases behind -

That sounds sensible but very disruptive and a big lot of jamfiling.

(And - aside - why it is not


Why are there two 'extra' /mylib folders? Is this historical or is/was
there some logic to it?)

As far as maintenance, the /Guild/MyLib/... structure also sounds a good
model for the less experienced/confident to try to fix things and test their
'improvements', without the risk of messing things up big time.

The big problem for would-be fixers is this risk?

It would be also be good to be able to move from /Sandbox or /Guild to
/Trunk 'seamlessly' as soon as code is accepted by some review process.

My 2p, FWIW
