Apple released macOS Big Sur also know as macOS 11 November 12th.

New Macs with the M1 chip require it, but put bluntly, we strongly recommend that you do not upgrade any other production Macs to Big Sur yet. Along with a complete user interface overhaul, it has significant under-the-hood changes that could pose compatibility problems for many workflows in the near term. We’ll be evaluating Big Sur with common productivity apps shortly and will update our advice about when it’s safe to upgrade as we learn more.

• As with macOS 10.15 Catalina, Big Sur will also not run 32-bit apps: If you rely on a 32-bit app, you’ll need to upgrade them or find alternatives. Some examples: Microsoft Office 2011, Adobe CS and some older versions of Adobe Creative Cloud.
• Backward-compatibility issues: If you upgrade to Big Sur, that may force you to upgrade an app you rely on. If the new version of that app saves its documents in a format that older versions can’t read, that could cause problems for users whose Macs either shouldn’t be upgraded right away or can’t be upgraded at all.
• Many times new operating systems have bugs. We usually recommend delaying a macOS upgrade until these bugs have been discovered and patched. This means after a few patches, 11.2, etc.
• MC Services controls updates and upgrades for clients under a Managed Services contract. We do our best to prevent these early upgrades but always want clients to be informed. Either way we can help you with the process.

If you have not changed the default settings on your Mac, you will get notices to upgrade to Big Sur.

To keep these from appearing, go the System Preferences > Software update and uncheck the box that says “Automatically keep my Mac up to date”

If you want to see what is coming in Big Sur you can check out these sites, but we would advise not updating your Mac until 2021.
