Release Notes

v0.9.21

Patch Changes

• Use rsbuild inline sourcemaps for JupyterLab extension (#​909)

  JupyterLab was refusing to load external source map files because they were
  being served with the wrong MIME type ('application/octet-stream' instead of
  the expected source map MIME type). This caused the extension to fail loading
  in version 0.9.20.

  Switching to inline source maps embeds the source map directly in the
  JavaScript bundle, avoiding the MIME type issue while still providing source
  map support for debugging.

v0.9.20

Patch Changes

• Override repr to avoid expensive trait serialization #​906 (#​906)

  Previously, AnyWidget inherited ipywidgets.Widget.__repr__ which serialized all trait values. This is costly because the repr might not even be shown to users, yet it forces a full serialization of potentially large data. AnyWidget now overrides __repr__ to use object.__repr__(self), which produces a simple <module.ClassName object at 0x...> format.

  To restore the previous behavior showing all trait values, users can define:

  class MyWidget(anywidget.AnyWidget):
      def __repr__(self):
          return traitlets.HasTraits.__repr__(self)
