Improved support for display 256x256 .ICO files

Hi, can I know what is this "Improved support for display of 256x256 .ICO files" in latest 9.5.2 version?

In Win7 I see same ugly very small 32x32 icons in folders/app/docs/files icons.
Opus is still limited to 32x32 in all modes and even 16x16 in List/Details modes.

Only just ICO files are 256x256 but this was in 9.1 too.
So what's changed from 9.1?

Previously, Opus would not display thumbnails for 256x256 ICO files that were not stored as PNG. Now it can.

It's literally for .ICO files, not for icons in general.

Support for 256x256 icons for all file/folder types is being worked on (and isn't as easy as it sounds since the API Windows provides for it are atrocious in my experience).
