> 5.620 is out with many improvements and bug fixes. This release addresses virtually every single workflow and performance problem that have been reported to our team in the last 2 weeks. The increased load times can be addressed by merging your history steps. So far the increased load times that we have seen were due to very long (500+ or 1000+ long) parametric history steps that didn’t take advantage of the parametric history. Large assembly related performance issues have been fixed too. Th…
