Discussion question: what are the major functional changes to Luminis that you have seen released in the 4.x.x releases of Luminis?

There are often technical reasons for upgrading Luminis due to bug fixes, technical capabilities, etc. But I am curious to hear what functional changes between the minor releases of Luminis 4 have stood out to the lumdev community as valuable or noticable?

Another way to ask the same question, if you were recently on a "recommended build" of Luminis 4.2.x.x, what reasons (other than bug fixes) have motivated you to upgrade to the next minor version?

Please make sure to include in your posts what version you came from and went/are going to, assuming you were on the recommended build version for example 4.2.0, 4.2.1, 4.2.2 or 4.2.3.
