Upgrade from 5.2.0 to 5.3.1 create issues

I have just upgraded from 5.2.o to 5.3.1 but it create issues and test get failed. Keywords like ‘verifyelementpresent’ and ‘click’ are unable to detect objects even if they are present, They passed on older version but failed on new. Everything is same, Any ideas ??

Few more updates regarding this issue :
Individual tags no longer work without xpath or any attributes (class, id, etc…), So I have some tags like “” that doesn’t have any attributes. Earlier it was working find in 5.2.0, But now I had to add xpath to make it work.

Can anybody please confirm this?
