Contextual Siri is supposed to offer users more personalized interactions: understanding schedules, recommending actions, and supporting live dialogue. However, launch dates keep getting pushed back. iOS 26.4 could be the first update to fully realize these features.

The update may also include new emoji
Some sources are speculating that iOS 26.4 will add a new batch of emoji. Usually, such updates are released in versions that get mass adoption quickly. For example, new characters were included in iOS 18.4.
While the addition of emoji isn’t considered a major innovation on its own, it does indicate Apple is preparing for a larger update. The main focus is expected to be on smart features.
