The Short Version
Apple released visionOS 26.5 for Apple Vision Pro, bringing bug fixes, security updates, and performance improvements to all users worldwide.
visionOS 26.5 is a security and bug fix update, not a big new release. The most notable addition is Genmoji, an AI emoji tool that arrived on iPhone a full year ago. Apple also pushed over 50 security fixes across its platforms in the same wave, covering devices going back five years. Install it, but do not expect anything surprising.
