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.
