License information is unclear

[swaldhoer]

The latest commits¹ changed the license information from MIT to GPL.

However, all source files, i.e., the most relevant if you e.g., vendor keras2c in your project, still state

"""
This file is part of keras2c
Copyright 2020 Rory Conlin
Licensed under MIT License
https://github.com/f0uriest/keras2c
"""

Could you please clarify whether this was intentioanl or otherwise what the actual license of the project is?
This is very crucial information when the change is from MIT to a copyleft-license like GPL.
