Suggested change

	<ul>
	<li>* Physical pixel size metadata is now carried over from inputs to exports when using TIFF or H5</li>
	<li>* Pixel label explorer: Easily find and jump to previously drawn brush strokes</li>
	<li>* New "multi-scale OME-Zarr" export format and better UX when adding multiscale datasets to a project</li>
	<li>* New variant of Object Classification workflow, using a label image as the second input</li>
