 * Version history
-* 1.8.1 Fixed bug after ML: was using V from unconstrained instead of constrained fit
+* 1.8.2 Fixed bug after ML: was using V from unconstrained instead of constrained fit
+* 1.8.1 Fixed bugs in handling robust non-cluster
 * 1.8.0 Reworked multiway clustering to first collapse data to one obs per all-cluster-var intersections.
 *       Reworked test stat computation for df>1 to mostly iterate over constraints rather than replications. Speeds AR test too.
 * 1.7.1 Changed residual dof for multi-way clustered, small-sample-corrected models to smallest number of groups across grouping variables
