Viewers no longer systematically hide the explorer window. However, it is possible to restore the previous behaviour in the preferences by checking the checkbox ‘Always display in front of the explorer window’
A new type of favorite has been added: multiple directory selection, which allows you to display the files in a set of directories with a single click
Multi-directory selection is much faster

Fix: occasional but recurring crash when updating a catalog containing many 2D files, depending on the max number of threads defined for 3DBrowser
