The release notes for this version of code should be able to answer that question for you. It is possible there are some open issues on that version of code but they may not matter depending on the configuration you are running.
Thanks for the reply...but unfortunately I can not upgrade it... i need to update only....just one more query, is this patch stable for update...I mean is there any open issue with this ??
The latest patch is always recommended of any version of code (For 15.3.4.6 it is 1-14). When you "update" the patch it is like performing a upgrade and will be placed on the opposite partition. I would not recommend sticking on the 15.3 code considering it is out of support. The current recommended code for the x460 is 16.2.2.4.
