Cego 2.20.22 发布，此版本现已提供下载：http://www.lemke-it.com/cego-2.20.22.tar.gz。

更新内容如下：

Fix in CegoQueryHelper::evalSelection for isAgg-case : int i =0; CegoField *pJF = 0; while ( i < jbufSize && pJF == 0 ) { CegoField* pJF = joinBuf[i].Find(*pF); ^^^^^^^^^^ if ( pJF ) { pF->setValue(pJF->getValue()); } i++; } The local variable lead an not optimized loop invariant, since the second condition predicate never terminates the invariant
Fix in CegoFactor::evalFieldValue : For the QUERY case, the select instance was not reset. Since the query starts from a undefined point, this might lead to "list position exceeded" exceptions
Added command line parameter validation for poolsize, numdbthread, numadminthread and numlogthread parameters
