This plugin is hidden under sidebar > tools > regenerate thumbnails. Once you start the regeneration process, it will show a progress bar and a summary of the images it has regenerated thumbnails for.

You can also regenerate individual image thumbnails by going to sidebar > media > image – there should be an option to manually regen thumbnail.

However, be careful when you regenerate your thumbnails – manually set thumbnails will be removed.
