 # Changelog
 
+## 1.7.x
+### 1.7.0: Feature - Automatically Add Missing EXIF Fields
+- Between versions 1.5 and 1.6, two new EXIF fields were introduced: `developer` and `time`.
+- If these fields were missing in the local EXIF file, the program would still load but crash when processing an image.
+- Previously, this could be fixed manually by adding the missing fields, something I could easily do myself, but not ideal for other users.
+- The program now automatically checks if the local EXIF file has these fields, and if not, it adds them with default values.
+- This might make it easier in the future to adjust local files.

 ## 1.6.x
 ### 1.6.0: Feature - Add Information from Developing Process
