i found out that the last version can just zoom with ctrl+wheel ..... how can make it zoom only with wheel scrolling  like before ? 

Its implementation changes.

From a few hours ago:

• In Edit → Preferences → Behavior → Scrolling, the setting Mouse wheel zooms by defaulthas been removed. This setting can now be set by disabling the modifier 'Ctrl' for Canvas zoom, and enabling it for Vertical pan instead (see section about 'Customization' below for more information).
• The Zoom correction factor in Edit → Preferences → Interface now works correctly for other units than mm and remembers values below 100%.
• There is an option now in Edit → Preferences → Interface: Show zoom percentage corrected by factorto adjust the number shown in the Zoom field in the bottom right corner of the Inkscape window to match the real world scale. The new option is active by default, so that, after adjusting the factor for your monitor, at 100% zoom, your document page is as large on the screen as it is in reality.
• In Edit → Preferences → Interface: Cursor size, the option to Enable cursor scaling allows users to work around too large and unsharp cursors in some cases

 

so no way to change to zoom with only wheel scrolling ? 😭😭

Thanks, Polygon!
