 Global `compression()` middleware introduces significant CPU and memory allocation overhead on unhandled routes (404s) and lightweight responses.
 Action:
 Always apply `compression()` as a route-specific middleware only to endpoints that return large payloads.
+## 2026-05-14 — Support Multimodal Requests
+
+Learning:
+To support OpenAI multimodal compatibility, message validation logic must allow the `content` field to be either a string or an array, as multimodal requests use an array of text/image objects.
+
+Action:
+Updated `isValidMessage` in `src/index.js` to accept an array for `msg.content`.

+## [1.1.34] - 2026-05-16
+### Changed
+* **[Lifecycle]:** Safely bumped dependencies via npm update. Verified baseline tests pass. Zero dead code was pruned.
+
+## [1.1.33] - 2026-05-14
+### Changed
+* **[Compatibility]:** Updated `isValidMessage` validation logic to support multimodal requests by allowing the `content` field to be an array, specifically reinforcing that empty array payloads and non-string types are correctly rejected.
+
 ## [1.1.32] - 2026-05-12
 ### Changed
 * **[Performance]:** Converted `compression()` from a global middleware to a route-specific middleware on the `/v1/chat/completions` endpoint. This prevents unhandled routes (404s) and lightweight responses from incurring unnecessary CPU overhead and memory allocation for compression.
