 # Feature Release
 
+### **(v0.237.006)**
+
+#### Bug Fixes
+
+*   **Sidebar Conversations DOM Manipulation Fix**
+    *   Fixed JavaScript error "Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node" that prevented sidebar conversations from loading.
+    *   **Root Cause**: In `createSidebarConversationItem()`, the code was attempting DOM manipulation in the wrong order. When `originalTitleElement` was appended to `titleWrapper`, it was removed from `headerRow`, making the subsequent `insertBefore(titleWrapper, dropdownElement)` fail because `dropdownElement` was no longer a valid child reference in the expected DOM position.
+    *   **Impact**: Users experienced a complete failure loading the sidebar conversation list, with the error appearing in browser console and preventing any conversations from displaying in the sidebar. This affected all users attempting to view their conversation history.
+    *   **Solution**: Reordered DOM manipulation to remove `originalTitleElement` from DOM first, style it, add it to `titleWrapper`, then insert the complete `titleWrapper` before `dropdownElement`. Added validation to check if `dropdownElement` is a valid child before attempting insertion.
+    *   (Ref: `chat-sidebar-conversations.js`, `createSidebarConversationItem()`, DOM manipulation order, line 150)
