UltiMaker Cura 5.3.0-beta.1

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.

Community translations:

• Updated French translations, contributed by @xommit
• Updated a typo in Japanese translations, contributed by @tamorikawa

Known critical issues:

• 🌍 Currently the translation files seem to be missing in these Beta builds. We are working on a solution so everyone can test this Beta in their preferred language. Translations are now available!
• Under certain angles, the Interlocking Structures are not effective, yet.
• The Gcode Reader Plug-in is broken since Cura 5.2, and will not load gcodes correctly yet.
• Some models have been slicing slower since Cura 5.1. #14108
• Reports have been coming in that Cura is running slow on Windows 11 #13820
• Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances.
