One major under the hood improvement in this new build is changes to memory handling in the data grid and the editor. Specifically exporting, sorting, grouping or filtering on a large result set is drastically improved and should now be fully useful to do on million row result sets and larger. We have also discovered and fixed a memory leak where the memory of an editor was not released when it was closed (Unfortunately this included the data in its result grid data so this could be a rather large leak at times).
