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 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 and is built on a custom version of OpenHarmony and Oniro OS. 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 it's kernel abstraction layer as user mode, which the OS itself shares lineage with lightweight LiteOS real time operating system for resource-constrained devices like wearables and IoT products.[5]

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.[6]

History

On August 4, 2023, at Huawei Developers Conference 2023 (HDC), Huawei officially announced HarmonyOS NEXT, the next version of HarmonyOS, supporting only native APP apps via Ark Compiler and native APIs in HarmonyOS SDK.[7]

The kernel of HarmonyOS NEXT does not include the compatibility layer of AOSP framework with Android libraries from EMUI in the user space and cannot run Android apk apps natively, as is the case with the dual framework HarmonyOS.[8][9]

On August 4, 2023, the developer preview version of HarmonyOS NEXT was opened for cooperating enterprise developers, and on January 18, 2024, to the rest of developers to build and test native mobile apps. The beta version was expected to be launched in Q2 2024, and the commercial version to be made available in Q4 2024. It has been revealed by Huawei that HarmonyOS NEXT system stack development goes back as far as 2015 after R&D incubation of HarmonyOS development in 2012.[10][11]
