## AI overview

This Codename One update explains that its iOS pixel-density lookup table omitted several newer iPhone models, causing inaccurate physical-unit rendering. The table and unknown-device fallback were updated, and the article also discusses iOS performance work related to Java, Project Valhalla, and the Vector API.

## Source excerpt

If you have shipped to an iPhone 14 Pro or anything newer, your density calculations have been wrong until this week. Also in this update, Codename One delivers the performance benefits that Java developers are still waiting on from the Vector API and Project Valhalla -- available today, and already making our Base64 on iOS faster than Apple's own.
