* In all previous versions, pen width depended on zoom in such a way that the strokes appeared the same visible width at any zoom, but were in fact narrower at zoom-in and wider at zoom-out. This behavior makes sense if you want to keep the same "feel" of the pen regardless of zoom; for example, if you zoomed in to make a small fix to your drawing, it's natural that your pen becomes physically smaller but feels the same to you. So, this behavior is kept as the default, but now we also added an alternative mode where your pen width is constant in absolute units regardless of zoom. To switch to this mode, use the checkbox on the tool's Preferences page (you can open it by double-clicking the tool button).
* The Width field in the tool's controls bar now changes from 1 to 100, which corresponds to the range from 0.01 to 1.0 in the previous version. If the "width in absolute units" mode is turned on, the value in this fields gives the width of the stroke in px units. In the default mode, the value of 100 gives 100px wide strokes only at 100% zoom, and strokes are correspondingly narrower or wider at other zoom levels.
