Cwa or cma?????

CWA - Cost and Works Accountant( which was known before, when a student pass his all three level examinations he was called as CWA, ACWA,FCWA respectively. 

But  now, 
CWA has been replaced with CMA, it is Cost and management Accountant. 
So here the professional is known as ACMA,FCMA respectively.

Meanings are same, but the essence is changed, now CMA's professionalls are globally recognised and therefore the ICAI(cost) decided it to be changed

PS: Both are same for the purpose and for the students and thier studies afterall.
