This was an intentional change done by upstream Nautilus developers. Showing a dialog by default makes problems for users that have external drives with FAT32-like filesystem, where all files are executable. See:
https://git.gnome.org/browse/nautilus/commit/?id=72d6c7ce7febd573 https://bugzilla.gnome.org/show_bug.cgi?id=601736
Like Borivoje said, it is easily configurable from the Preferences dialog.
