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

## DDE commands accept arguments

Commands sent via DDE can take arguments, the same as in custom shortcuts ([#5383](https://github.com/sumatrapdfreader/sumatrapdf/issues/5383)).

## Loading message in tab

While a document loads, its tab shows a "loading" message instead of the home page ([#5385](https://github.com/sumatrapdfreader/sumatrapdf/issues/5385)).

## Install 32-bit on 64-bit Windows

The installer lets you install the 32-bit version on 64-bit Windows ([#5379](https://github.com/sumatrapdfreader/sumatrapdf/issues/5379)).
