This release does not yet contain the new tree support implementation by @ThomasRahm. You can download a special Cura version for that here.
Interlocking Structure Generation
This new setting enables you to interlock multiple materials together, even if those materials are not compatible, contributed by @BagelOrb. Try it for yourself with this test model.
Brim per Material
A brim can now be printed with multiple materials in the same model, contributed by @BagelOrb
Updated Recommended Print Settings Menu
The number of settings available in the recommended has expanded. The redesign will make it easier to use intent profiles or save custom profiles.
