+## [0.9.9] - 2024-03-22
+- Fix: Compile started failing for express generators with the following error: 
+
+  ```
+  error TS2688: Cannot find type definition file for 'mime'.
+
+  The file is in the program because:
+    Entry point for implicit type library 'mime'
+  ```
+
+  The root cause is because a breaking change was released in v4 of the mime library. 
+  This is now fixed because the generator resolves to v3 of the library as 
+  specified in this GitHub [issue](https://github.com/firebase/firebase-admin-node/issues/2512). 
+
 ## [0.9.8] - 2024-03-22
 - Improvement: Enhance serde performance by reducing reliance on async behavior and lazy async dynamic imports.
 - Internal: Shared generator notification and config parsing logic.
