 1. The date it was marked for deprecation (its "over the hill" birthday)
-2. The ERPNext version in which it will be removed (its "graduation" to the great codebase in the sky)
+2. The ERPNext version at the beginning of which it becomes an error and at the end of which it will be removed (its "graduation" to the great codebase in the sky)
 3. A user-facing note on alternative solutions (its "parting wisdom")
 
 Warning: The global namespace herein is more patched up than a sailor's favorite pair of jeans. Proceed with caution and a sense of humor!
