<div>I'm looking forward to the update to 5.6.0. Is the

could you recommend me to pause the evaluation of drools,

<div>We consider to use drools in a larger project, and

Not putting out warnings when some release is known to be
broken is a<br>
rather dark spot on the gloss of Drools. I have urged this
before,<br>
mainly because<br>
not warning users is a primary cause for them wasting time
and effort.<br>

Keep carping...<br>
