Apple has rolled out beta 4 updates for its iPadOS 26.4, tvOS 26.4, and visionOS 26.4 software today. This marks the latest installment in Apple's unusually frequent beta cycle, with new releases arriving weekly since the first 26.4 pre-release version debuted last month.

The rapid update cadence represents a departure from Apple's typical beta schedule, which often includes two-week gaps between releases. Last week's cycle was particularly active, with iOS 26.4, iPadOS 26.4, and watchOS 26.4 each receiving two distinct beta 3 versions as Apple worked to address bugs quickly.

These beta 4 updates continue that pattern of rapid iteration. Apple's 26.4 software lineup is expected to launch publicly in late March, making these beta releases critical for developers preparing their apps for the upcoming changes.
