Is there a Safari update beyond version 26.0?

As I pointed out the release of Safari 26.01 was specifically for macOS 15 Sequoia users only. There is no Safari 26.01 for macOS 26 Tahoe users. If you are still running macOS 15 Sequoia that update should be available in Software Update panel of System Settings.

In addition the article you posted a link to clearly states the update is for macOS 15 users. If i wasn’t clear enough about this I apologize.

The release of that update was for macOS 15 Sequoia, not macOS 26 Tahoe. If you are still running macOS 15 then check for the update in System Settings.

For what it's worth developers have received notice of Tahoe 26.1, iOS 26.1, iPadOS 26.1 beta releases for testing. They are not out for the public yet.
