Just late September this year the company I am working for approved the use of Version 12 (from V10 and V11) after their thorough review of its latest function. Now dialux has version 13. This is a bit disappointing since we can't use the features of V13. Reviewing of the software and approval by our company take months making sure calculation results are accurate and safe to install (IT software policy). I am not sure if other companies have similar situation, but it would be helpful if dialux use patches instead of changing version numbers after a few patches

Does Dialux create a version year or every after 3 or 4 patches?
