Apple’s watchOS 26 Public Beta 4 reintroduces blood oxygen monitoring for the Apple Watch Series 9, Series 10, and Ultra 2 models in the U.S., a feature previously disabled due to a legal dispute. The redesigned implementation shifts raw sensor data to the paired iPhone for processing, with results visible in the Health app. This workaround stems from a patent-infringement case by Masimo, which has now sued U.S. Customs for allowing the restored functionality. While beta testers can regain access to this health feature, its future hinges on the legal outcome. The update underscores Apple’s commitment to health tracking, even as it navigates complex patent challenges.

Apple has released updated developer beta firmware (build 8A5343a) for AirPods Pro 2 and AirPods 4, requiring devices running iOS 26, iPadOS 26, or macOS 26. The update continues to expand and refine beta features tied to Apple’s upcoming operating systems. While specifics of enhancements remain limited, earlier beta firmware hinted at additions like camera remote control, higher-quality audio recording, and improved call handling—particularly for H2-chip-equipped earbuds. This iterative rollout allows Apple to fine-tune feature behavior before wider release. Public beta testers can also access this update, marking Apple’s first public firmware beta for its earbuds. It reflects Apple’s push toward more integrated audio experiences across hardware and software platforms.

Zoom has announced that upcoming updates will no longer support devices running iOS 13 or iOS 14, requiring a minimum of iOS 15 for continued app functionality. The change, noted in release notes for version 6.5.10, reflects shifting usage trends and a need to streamline feature development. Though affected iPhones and iPads remain capable of running iOS 15, enterprise users managing older devices may need IT intervention. This move follows broader industry patterns where app developers gradually phase out legacy OS support. While end users won’t immediately lose access to existing Zoom versions, they will miss out on feature improvements and security updates moving forward.

Google Docs has introduced a powerful new accessibility feature that uses Gemini AI to read documents aloud in natural-sounding voice. Users can generate audio via the Tools menu or insert an audio button directly into the document, enhancing accessibility and convenience for proofreading or consuming written content. Playback offers voice and speed customization for better comprehension. Initially available on desktop versions, the feature is offered to Google Workspace business, enterprise, and education users, as well as AI Pro and Ultra subscribers. By leveraging Gemini’s expressive text-to-speech, Google is offering a richer alternative to traditional speech tools—positioning Docs as a more accessible, dynamic environment for both reading and writing.

OpenAI’s CEO has teased GPT‑6, which will emphasize persistent memory and personalization, moving beyond raw computational power. Unlike previous models, GPT‑6 aims to remember past conversations, user preferences, and long-term goals to create more coherent, emotionally aware interactions—closer to a trusted assistant than a forgetful chatbot. This new architecture enables adaptation over time, reducing repetitive context-setting and improving relevance. However, storing and utilizing memory raises privacy concerns, prompting OpenAI to prioritize user controls, transparency, and ethical safeguards. While no release date has been confirmed, GPT‑6’s memory-driven approach represents a major milestone toward human-centric AI—potentially transforming it from a tool into a seamlessly integrated partner in daily life.
