Sigma MC-11 firmware?

I have a MC-11 adapter on version 1.05 firmware. The latest firmware is 1.16, so I was thinking about upgrading the firmware.

I was using a Canon 70-200/2.8 L version I lens with AF-C this weekend and while it worked 98% of the time, it was acting a little strange (AF changing to MF by it self) and other little quirks. I had to power cycle the camera to go back to AF.

I know Sigma doesn't officially support Canon lenses but I only use Canon lenses with this adapter.

For those who use the MC-11 on firmware 1.16 with Canon lenses, have you encountered any problems?

I read firmware after 1.05 broke Canon compatibility but was fixed with later firmware versions.  Are there any downsides to upgrading to 1.16 for Canon lenses?
