Diffractor 121 can now be downloaded here.
This release changes the UI so that all selected items are shown in the preview panel. This means if you select two images, they are both displayed. This is useful when comparing photos etc. This also simplifies the user interface. Tools now always apply to the currently selected items. In the past, they could either apply to the shown items or the selected images; depending on where you selected the menu option.
Support has also been added for displaying CR3 raw photos and WEBP images.
There are also multiple small bugs fixed for existing functionality. Including a fix to detecting duplicate photos - this didn’t always work in the past reliably.
Last thing: Diffractor will now automatically update unless you disable this feature in the system settings.
