1. Removed check if camera has attribute 'sensor size'. This option was needed for backwards compatibility. Not needed anymore 2. Moved adding composition's name from blender's toolbox to After Effects. User specifies name when running script in AE. 3. Added option to export selected objects' scale. 4. Rotation and scale export is now the option. User can include or exclude those properties. 5. Removed 'prefix' from AE's layers' names. This option was just creating mess. No real benefits from having this option 6. If no camera is selected - at least scene's camera will be exported (if exists)
