There isn’t a new 2021 version of OneNote, but a version of OneNote is installed with Office 2021. For more information, see Deployment guide for OneNote.
All products in the Office 2021 are available in both 32-bit and 64-bit versions. We recommend 64-bit on computers that have 4 GB or more of memory. But you should assess application compatibility and other factors that might require you to use the 32-bit version. For more information, see Choose between the 64-bit or 32-bit version of Office.
