         removed in future versions of the library. It is only intended for
         back-compatibility use.
 
+      - Added support for PNM images.
+
+      - Added STBI_MALLOC, STBI_REALLOC, and STBI_FREE macros for replacing
+        the memory allocator. Unlike other STBI libraries, these macros don't
+        support a context parameter, so if you need to pass a context in to
+        the allocator, you'll have to store it in a global or a thread-local
+        variable.
