You can now use the Graphics Processing Unit (GPU) of your system for image editing in Lightroom Classic. Previously, GPU usage was primarily utilized for display but the new release gives you an additional option to turn on the GPU for image processing. With this added support, you will experience smoother and enhanced performance for overall image-editing processes. To enable this option, do the following:

In the Collections panel in Library module, you can further organize your library by adding a color label to the collections, collection sets, and smart collections. This is a great way to stay organized and quickly differentiate between collections.
For more information, see:
Color labels can now also be renamed for folders and collections. Previous version of Lightroom only supported renaming color labels for images. To edit the color labels, go to Metadata > Color Label Set > Edit.
Changing a color label will alter your smart collections.
For more information, see Edit color label sets.
With this release, we have added a new file format for your export needs. You can now export images in the PNG file format. Importing PNG files have been supported in previous Lightroom versions.
For more information, see Export files to disk or CD.
Merging group of HDRs or panoramas is more efficient than ever. Rather than merging each group of images one by one, you can merge a batch of grouped images at once. First, combine each image group into a stack. Then select the stacks, right-click and select the appropriate merge option - HDR or Panorama. This will create an HDR or panorama for each stack.
Index numbers are now included in the filmstrip so you can easily refer to your images in Loupe view. This is especially helpful when reviewing collections with peers or clients. To turn off index numbers in the filmstrip, go to Preferences > Interface > Filmstrip and deselect the Show Index Number check box.
