I just installed the 1.11 firmware upgrade. These are the differences that I have noticed:
1) They changed the font for the time + label that goes on the video image. It is now much bigger and easier to read.
2) They changed the night mode sensitivity - they lowered the threshold so it is more likely to stay in day mode, and when it does go into night mode there is now a timer to prevent it from going back into day mode too soon.
3) Regarding what sim said in an earlier post - MPEG4 has always been there. Also, I do not see the Auto Mute option under Audio and Video.
4) New IP Filter settings to control access to your camera by allowing / denying IP addresses or subnets.
5) New HTTPS settings
6) Motion detection settings are now broken for me. Instead of a window showing the video where I can draw the motion detection regions on, I get a Java error, and the error says ClsasNotFoundException for MD.class. Nice going, D-Link.
7) There is now Sound Detection settings. I am guessing this is a new trigger type. You get to set what sound the sound level for the trigger is. I am not sure if it sends out a motion detection event or what.

If you have SD recording on, there is now a message saying "To format the SD Card in the camera, please disable SD Recording first." Good. This was not obvious before.
There are no other changes that I can see, although I do not use every feature of this camera.
