 **Enhancements:**

+- Documentation and testing improvements.
+
+**API status and Breaking Changes:**
+
+- `seems?/1`: returns the image type found (e.g., `:bmp`, `:tiff`), or `nil` if it is not recognized.
+  For JPEG images, it returns `:jpeg` instead of the alias `:jpg`. However, the alias `:jpg` can be used in `{seems?,type,info}/2` functions.
+- `seems?/2`, `type/2`, and `info/2`: these functions will **raise an error if an unsupported image type is provided**.
+- `seems?/2`: **fully boolean**.
