A few people have expressed an interest in how Lightroom will handle the installation of Photoshop CS4. When CS4 is installed, Lightroom automatically detects it and updates the Edit in Photoshop menu to reflect this. No user intervention should be necessary. There are quite a few changes in Photoshop CS4, so users may feel the need to leave CS3 installed. You can still use CS3 as an External Editor, in which case the old ‘Edit with Lightroom Adjustments’ dialog will appear, and an intermediate file will be created.
