Pulldownit , the destruction plugin, is already available for Maya 2023 an brings an important enhancement, Shatter it tool is now 4 times faster. This new update v 5.3 will be available for the rest of supported Maya versions in the following weeks.

Maya 2023 itself brings quite a lot of improvements in animation, modeling, and performance.  Boolean operations have been revamped with new modes, more intuitive visualization in the viewport and a new Boolean Stack editor for easily manage your changes. Retopology tool has been boosted with a new auto remesh option allowing to get quickly good results with less preparation of the scanned model. There are more deformer options and important performance improvements when modifying hi-poly meshes, besides you can now control the transparency level of the wireframe on shaded, which is very useful working with dense meshes.   

Regarding Animation Autodesk has introduced a new Blue Pencil tool allowing to create 2D drawings and annotations directly in the Maya viewport which are saved with the scene.

There are also usability improvements to the Sweep mesh tool and Arnold render has been updated, besides Bifrost now support USD assets.

Since several years ago Autodesk is focused in strengthen Maya for animation tasks, and probably it counts with the most powerful toolset on this area, this new version includes also important enhancements for modeling, that’s good, however making Bifrost supporting USD assets isn’t the most appealing update for those working in VFX , hope Autodesk moves forward and devotes time to improve seriously Bifrost aswell.
