[Coin-lpsolver] CLP: Question about current state of QP solving capabilities.

Dear COIN-OR developers,
I have browsed through CLP's documentation, FAQ, and example programs,
and was left in doubt a bit about CLP's QP solving capabilities. On the
one hand, the FAQ entry clearly states that QP solving using the
interior-point code is in an early state of development only, but
nonetheless usually more efficient that the quadratic simplex code. On
the other hand, that FAQ entry dates back to 2004 and seemingly refers
to a 0.9x version wheres I find 1.5.0 being the most recent revision.
I would be extremely grateful if you could elaborate on the current
state of the two algorithms regarding the solution of convex /
semidefinite QPs with a size of ~500 variables and ~1000 linear
constraints ?
Best regards,
Christian Kirches
