The MIT License permits Commercial use, Distribution, Modification, and Private use, while requiring the inclusion of the License and copyright notice and limiting Liability and Warranty (source: https://choosealicense.com/licenses/mit/).
I want to add one thing: that all modifications must be indicated explicitly with date and by whom.
That way, my open software can be freely modified outside of a repository but with accountability.
Is there an existing license that offers close to these terms? Or may I simply edit the MIT License and include it in my software as "modified from the MIT License"?
