Version 4.00 doesn't really mark any significant changes but the previous version which was 3.99 could only be logically followed by incrementing the major number.
Version 4.40 brought in the first native 64 bit release which improved the performance of loading large images (more than 25 megapixels).
New version 4.30 - Program loads, image displays, image saves as original.
No other operations evaluated; tested only to confirm "Paint" feature still non-functional
What does not
As with versions past 4.25, making any edits with the "Paint" feature can not be saved onscreen, or to the file, if the Paint toolbar is closed; any changes are lost.
What was not tested
While "paint" was not a core component (was a third party Plugin; now part of the "official "plugins), it makes this program more than just a "crop-and-lighten" photo editor. Having this now built-in feature work (once in older versions) and then no longer, and in a manner of frustration (it works partially) implies a Bronze rating.
