+## [0.8.2] - 2024-02-21
+- Fix: File upload endpoints no longer fail to compile because the reference to 
+  the mime type variable is present.  
+
+  ```java
+  // Code that failed to compile
+  String fileMimeType = Files.probeContentType(file.toPath());
+  MediaType fileMediaType = fileMimeType != null ? MediaType.parse(mimeType) : null; // mimeType undefined
+  // Code that now compiles
+  MediaType fileMediaType = fileMimeType != null ? MediaType.parse(fileMimeType) : null;
