Got an update to S3 yesterday.

Hi,

I am from India and yesterday noon I got an update to my S3. The build number was changed from

JZ054K.I9300XXEMC2 to JZ054K.I9300XXEMG5.

It was 82.90 Mb. I am just trying to figure out what the update was about. When it asked me to confirm about installing the update it said "added a new feature". So how can I know what the update was about? Did anyone here get it?
