This update has : New camera is introduced. Software is backward compatible with old camera phones as well.
You might be thinking this update was an old one which you got in May 2013, but if you remember the update you used it was :
and this is:
If you have the 4.2 update you have downloaded earlier you can check with it.
I assume you can get this update also by visiting the Micromax Service Center as well.
I am not sure if they will release a 4.3 or a 4.4 now :P
I hope this change is suppose to be a OTA update probable a update.zip file as I don't see a big change log file, just a camera update.
But the above link file is for flashing and it contains the full Firmware/Rom.
I am attaching the Release Version Details in excel sheet.

You all might be aware of this method to Flash and upgrade Canvas HD as you might have already upgraded from 4.2.1 to 4.2.2.
If you had problems when you did that you might wanted to update this by visiting a Micromax Service Center or try to refresh you OTA update by going to system upgrade.
