 ### Changed
 
-- Nothing.
+- [#379](https://github.com/zendframework/zend-diactoros/pull/379) removes extension of `SplFileInfo` by the `UploadedFile` class. The signatures of `getSize()` are potentially incompatible, and `UploadedFile` is intended to work with arbitrary PHP and PSR-7 streams, whereas `SplFileInfo` can only model files on the filesystem. While this is technically a BC break, we are treating it as a bugfix, as the class was broken for many use cases.
