HarmonyOS version history

HarmonyOS NEXT (Chinese: 鸿蒙星河版; pinyin: Hóngméng Xīnghébǎn) is a proprietary distributed operating system and an iteration of HarmonyOS, developed by Huawei to support only HarmonyOS native apps. The operating system base is primarily aimed at software and hardware developers that deal directly with Huawei. It does not include Android's AOSP core and is incompatible with Android applications.^[3][4]

While on the one hand discarding the common Unix-like Linux kernel, the NEXT version also replaces the old HarmonyOS multikernel for its custom unified proprietary system built on OpenHarmony and global variant Oniro OS for global markets.^[5] The rich execution environment (REE) version of HarmonyOS microkernel is placed at its core with a single framework as kernel mode; also the new kernel architecture built on OpenHarmony and its kernel abstraction layer as user mode, which the OS itself shares lineage with lightweight LiteOS real time operating system for resource-constrained devices like smart wearables and IoT across all smart Embedded products.^[6]

The first internal preview version of the system was revealed on August 4, 2023, and the first preview version was released to registered public developers on January 18, 2024.^[4]

The devices tested on the developer preview version of the system were the Mate 60, Mate 60 Pro, and Mate X5 phones in the first batch.^[7]
