+<i><a href="https://youtu.be/kRj7pR4OkQA">Watch the launch event</a> to learn more about Ultimaker Cura 5.0 beta.</i>
+
+* New slicing engine
+Following special beta releases to test the Arachne engine, we are pleased to announce our new slicing engine is here in Ultimaker Cura! This all-new engine uses variable line widths when preparing files for printing, meaning you can now print thin and intricate parts more accurately and with greater strength. 
+
+* Renewed the Ultimaker Cura Marketplace
+We have streamlined the workflow for accessing the Ultimaker Marketplace inside of Ultimaker Cura. The UI has been improved and it’s now easier and faster to find and install plugins and material profiles.
+
+* Improved print profiles for Ultimaker printers
+The new slicing engine in Ultimaker Cura 5.0 beta has helped us to improve our print profiles. This means that users of Ultimaker printers can achieve speed increases of up to 20%.
