 ## Library & Tooling Updates
 
+### 🐦 [Puffin Profiler]
+
+Pufin is a simple instrumentation profiler created by [Embark]
+where you can opt-in to profile parts of your code.
+
+``` rust
+fn my_function() {
+    puffin::profile_function!():
+    ...
+    if ... {
+        puffin::profile_scope_data!("load_image", image_name):
+        ...
+    }
+}
+```
+
+The collected profile data can be viewed ingame with [imgui-rs].
