Details

ResourceFunction["ConvertLegacyPresenterStylesheet"] considers a stylesheet notebook to be any notebook that contains a StyleData cell.

A working notebook uses a private stylesheet if the working notebook's StyleDefinitions option is set to a Notebook expression.

If the NotebookObject nbobj or Notebook expression nbexpr are working notebooks with a private stylesheet, then their private stylesheet is converted.

Presenter stylesheets prior to 14.2 used option values like Dynamic[0.03*CurrentValue[{WindowSize,1}]] to scale options such as FontSize, CellMargins, and CellFrameMargins.

Presenter stylesheets starting in 14.2 use a notebook-level Magnification setting to scale the notebook content.

Dynamic references to WindowSize are removed in favor of constant values.

The primary monitor's aspect ratio determines the conversion of CurrentValue[{WindowSize,2}], defaulting to 16/9 if the aspect ratio can't be determined from the primary display.

StyleHints settings set at the notebook scope are updated to use Association inheritance.

Dynamic references to StyleHints are updated from CurrentValue to AbsoluteCurrentValue.
