Leica has released new firmware, mostly concerned with adding support for newer lenses. http://us.leica-camera.com/Service-...egory=93710&subcategory=&type=&language=93871 I do not plan on upgrading the M9 past 1.176, which is stable. After that- built in battery test, which has never given me a problem. I've read that some people have problems with the soft/discrete mode with 1.196. The "Improvements" for this firmware, Support of the new lenses: Leica Summarit-M 35mm f/2.4 ASPH. Leica Summarit-M 50mm f/2.4 Leica Summarit-M 75mm f/2.4 Leica Summarit-M 90mm f/2.4 of course, you never know when an embarrassing bug fix was snuck in by the author...I'll be watching the m Monochrom in discrete mode for glitches. On the M8 firmware- I can confirm that the "Button Dance" to unlock RAW mode still works.
