   FIRMWARE UPDATE 4.1.0

   IMPROVE​MENT

   • The warning message displayed upon power-up of the camera in which a BP-SCL4 rechargeable battery is used, was removed.
   • Pictures taken in portrait format will now be displayed in full screen view.
   • A menu option was added, in which focus peaking will be displayed only when focusing is done manually via the MF focus ring.
   • The currently selected AF mode will now be displayed in the form of an additional icon in the upper status bar.
   • In AF mode, Tracking will display the frame in the color of the respective detection status. Tracking will remain inactive when no person or animal is​ detected; green markers signify focus.

   TROUBLESHOOTING

   • An issue occurring in user profiles was remedied: The camera would sometimes freeze when switching from a profile with Leica FOTOS = Off to a profile with Leica FOTOS On. This behavior was corrected.
   • The color matrixes stored in DNG files were updated. As a result, color rendering in third party software using these matrixes for color presets is now improved.
