v3.4.5: Zoom stays put when you switch layers

A minor revision that keeps your view in place as you move between layers.

Released October 29, 2026. Auto-update will deliver v3.4.5 to existing installs over the next few hours.

Switching layers no longer resets the zoom. You can zoom in on a change and step through the layers to see what else sits at that spot, without zooming back in on each one. GerbDiff still fits the whole board when a comparison opens, and Reset Zoom (Ctrl+0, or Cmd+0 on a Mac) brings it back at any time. The fitted view is now the same on every layer, so the board no longer shifts slightly as you move between copper, silkscreen and drill.

This release also fixes zoom and pan with Auto-Align turned off, where every zoom or pan used to snap back to the fitted view. Nudging the manual alignment with the arrow keys no longer resets the zoom either, so you can line up a fiducial up close.

Thanks to the user who suggested this.
