+## Potential bugs
+
+### Avoid keeping `Font` (and `Image`) references across multiple frames
+
+*Rack for DAWs* uses a different OpenGL context each time the plugin editor window is closed and reopened.
+This means that if you load a `Font` in a widget's constructor with `font = APP->window->loadFont(...)`, the OpenGL font reference will be invalid if the window is reopened later.
+
+Instead, save only the font path, and fetch the font each frame in `draw()`. Example:
+```cpp
+std::shared_ptr<Font> font = APP->window->loadFont(fontPath);
+if (font) {
+	nvgFontFaceId(args.vg, font->handle);
+	...
+}
+```
+`loadFont()` caches the font by its path, so this operation can be efficiently called in `draw()` every frame.
+
+*All of the above also applies to `Image` and `loadImage()`.*
+
 ## Optional v2 API features
 
+### SVG load function
+`Window::loadSvg()` has been moved to `Svg::load()`. Search and replace:
