Change license in accordance with SDL 2 library?

[Free-Pascal-meets-SDL-Website]

The SDL2 lib. has adopted the zlib license. For best compatibility and wider spread usage of the units it may make sense to adopt this license for the SDL 2 units, too.

What do you think?

They don't differ much, but I guess I could also allow licensing the headers under the zlib license.

This is a good idea, since I think it would make them even more attractive. Both licenses complement each other in kind of a way (https://choosealicense.com/appendix/#trademark-use):

Differences only:

Permissions:

MPL: This license provides an express grant of patent rights from contributors.

zLib: This license explicitly states that it does NOT grant any rights in the patents of contributors.

Conditions:

MPL: Source code must be made available when the software is distributed.

Limitations:

MPL: This license explicitly states that it does NOT grant trademark rights, even though licenses without such a statement probably do not grant any implicit trademark rights.

(got information and statements from source link above)

Done.
