<｜begin▁of▁sentence｜>### Instruction:
As a mediator, you have been facilitating communication and conflict resolution between two teams in a software development company. The teams have been using a function called 'deprecated_function' in their respective projects, but it has now been marked as deprecated. You need to help the teams reach a mutually acceptable agreement on how to alert the users of this library that 'deprecated_function' should no longer be used and may be removed in future releases. The function is still implemented for compatibility purposes, but users should transition to using the new alternative methods.
### Response:
import warnings

# Function marked as deprecated
def deprecated_function():
    warnings.warn('This function is deprecated.', DeprecationWarning, stacklevel=2)

# Usage of deprecated function
deprecated_function()
