New in the SumatraPDF [pre-release builds](https://www.sumatrapdfreader.org/prerelease):

## Scrollbars setting and Change Scrollbar dialog

The new `Scrollbars` advanced setting picks the scrollbar style: `windows`, `smart`, `overlay` or `hidden`. It replaces the `HideScrollbars` and `UseOverlayScrollbar` settings. The new `Change Scrollbar` command (`CmdChangeScrollbar`) opens a dialog to pick the mode.

## Shrink To Fit zoom

New `Shrink To Fit` zoom mode (`CmdZoomShrinkToFit`): pages smaller than the window show at 100%, larger pages are fitted to the window. It is in the zoom menu and command palette, and works from the command line.

The Change Language dialog has a search box at the top. Type to filter the list of languages.

## Show Menu menu item

A `Show Menu` menu item makes it easier to turn the menu bar back on ([#5464](https://github.com/sumatrapdfreader/sumatrapdf/issues/5464)).

## No more "make default PDF reader" dialog

Removed the dialog that asked to make SumatraPDF the default PDF reader.
