Microsoft Brings back Mainstream Support for OneNote 2016
Today Microsoft announced that it will extend mainstream support for OneNote 2016, reversing their earlier decision to stop adding new features to OneNote 2016. This means you can continue to use OneNote 2016 and enjoy the benefits of Onetastic for the foreseeable future. OneNote 2016's support dates are being aligned to that of Office 2019. Office 365 subscriptions are being also updated to include OneNote 2016 by default in the near future.
