Change notes:

Fixed ISO memory bug by giving two memory options in the menu. If you have the ISO memory bug, change your memory location to “FLA” on the S tab of the menu
Added ND filter option at the bottom of the main menu
Fixed bug where meter would shut down sometimes after a flash was detected
Added ISOs from 1 to 1024000 in 1/3 stop increments
Animated charging / charged indicator when plugged in (only when off/shut down)
LUMO can now be used when charging
Improved flash/ambient ratio calculation accuracy
High ambient levels warning when in low range flash mode - high ambient levels can swamp the flash detector, requiring you to switch to high range flash mode to detect the flash fire. This message is shown when you ready the meter for flash based on the ambient level at that moment.

Change notes:

Faster screen draws
New method for updating firmware, which is intended to prevent accidentally entering program mode if the buttons are pressed in a pocket
