+## 2.17 🚀 Extrusion geometry 🚀
+- performance: Tube rendering is now faster and more accurate, thanks to a new custom geometry
+- feature: The parser can calculate layer height for each layer. It is used in tube rendering as the line height of extrusions
+- options: New option `lineHeight`, that overrides the height of all extrusion lines in tube rendering
+
+The repo also got some improvements:
+- Automatic deploy of the demo when pull-requests are opened and merged

 - new experimental mode: tube rendering
 In this mode extrusion lines are rendered using volumetric tubes using THREEjs TubeGeometry. Currently this mode is still under development and considered experimental.
 
@@ -62,7 +70,7 @@ If the difference in Z exceeds the threshold a new layer is allocated.
 If not specified, the default value is 0. (0 meaning a new layer is allocated for each and every increase in Z, however tiny.)
 
 Setting a non-zero value helps to reduce the number of layers that are allocated in memory, which would otherwise cause lagging or even a lock up for spiral vases and such.
