Firmware version 1.2 has been released for the Panasonic LX3.
Improvements are listed as:
- Improved white balance flash mode setting when DMW-FL220 is connected.
- Proper setting of shutter speed on iA mode and Scene mode when OIS is turned ON.
- Proper Exif information in the JPEG picture file.
Considering I haven’t had any issues relating to these I’m not expecting to notice any differences, however being a compulsory upgrader I ran the upgrade anyway 
Only issue being the battery was at 2/3rds capacity according to the indicator, and unless the battery is fully charged you don’t even get prompted for the upgrade, sneaky!
