There IS no change. Article 1 of the Indian constitution says, "India, that is Bharat..." and the official Hindi versions starts with-translated- "Bharat, that is India...."
All the Govt is doing is giving primacy to the Sanskrit word over the English (Latin?) word.
The word "India" cannot be banned without changing the constitution. However, govt communications can change the primacy of one of the names.
RE: All the Govt is doing is giving primacy to the Sanskrit word
If that is the case, then what will be the official name used in daily international transactions from now on?
Will the United Nations use the Sanskrit name? Will the Olympic Games, International meetings, newspaper references, etc. use the Sanskrit name?
