The November 2019 Lightroom updates are now available. Lightroom Classic
includes the ability to export the same photos as multiple sizes/formats in a single export, content aware fill for panorama edges and more. It does require a catalog format upgrade and there are updated system requirements, so you may want to wait a few days before upgrading. Lightroom (cloud-based service)
has export options (such as TIFF format, renaming and color space), custom sort order on the desktop, copy/paste to multiple photos on iOS and more. The Missing FAQ and Edit Like a Pro eBooks
are already updated for the changes.
