The version history of the HarmonyOS distributed operating system began with the public release of the HarmonyOS 1.0 for Honor Vision smart TVs on August 9, 2019. The first expanded commercial version of the Embedded, IoT AI, Edge computing based operating system, HarmonyOS 2.0, was released on June 2, 2021 for phones, tablets, smartwatches, smart speakers, routers, and internet of things. Beforehand, DevEco Studio, the HarmonyOS app development IDE, was released in September 2020 together with the HarmonyOS 2.0 Beta. HarmonyOS is developed by Huawei. New major releases are announced at the Huawei Developers Conference (HDC) in the fourth quarter of each year together with the first public beta version of the operating system's next major version. The next major stable version is then released in the third to fourth quarter of the following year.
The first public release of HarmonyOS 1.0 with LiteOS and Linux kernel space occurred with the release of Huawei's former brand Honor Vision smart TVs on August 15, 2019, after it was announced on August 10, 2019, as the first HarmonyOS powered commercial product in Huawei's domestic market, China. [1]
HarmonyOS 2.0 with Linux kernel that carried AOSP dual-framework with OpenHarmony L3-L5 source code branch was released on June 2, 2021, commercially in Huawei's domestic Chinese market, as de facto Beta testers for Chinese users, and was quickly adopted by 10 million users within a week. [2] It was gradually rolled out globally to tablets, smartwatches and bands in Huawei's product lines between the second half of 2021 and the first half of 2022. Followed by HarmonyOS 3.0 API 8 iteration with introduction of declarative programming and stronger Super Device connectivity with terminal devices in July of 2022.
HarmonyOS 3.1 with API 9 and an enhanced feature built for Qualcomm Snapdragon chipsets set was released March 30, 2023 that was first preinstalled on the latest Huawei flagship smartphones Huawei P60 series. [3]
The current release HarmonyOS 4.0 was released on August 4, 2023 with OpenHarmony 3.2 API 9 that saw reduction of AOSP codebase on some started and small Linux kernel mode devices in transition with OpenHarmony L3-L5 codebase expansion, followed by OpenHarmony 4.0 API 10 October 26, 2023 where both versions are in line with earlier HarmonyOS NEXT builds that is the unified modular OS software stack, closed distro branch from OpenHarmony L0-L2 codebase branch with main kernels of Linux kernel standard, small and LiteOS kernel with M small and A mini systems conglomerated, alongside global Oniro OS main kernels, Yocto Linux kernel which carries Linux syscalls on POSIX components for standard, small and mini devices on Zephyr kernel in user mode of HarmonyOS NEXT system that carries the new retrofitted Microkernel kernel mode in latest builds.[ citation needed ]
On 18th January 2024, Huawei released it's core software operating system, custom OpenHarmony based HarmonyOS NEXT Developer Preview 1 for all registered public developers in China that will be integrated into the next HarmonyOS Galaxy Edition (Star River) version of HarmonyOS NEXT, folded into consumer HarmonyOS 5 version, the successor of current HarmonyOS which was announced at HarmonyOS Developers event held in China that is due for commercial release in Q4 2024 that aims to replace the current dual-framework closed L3-L5 OpenHarmony source code version of HarmonyOS that contains Linux, AOSP and LiteOS compatibilities next to native HarmonyOS APIs which versioning are now streamlined with OpenHarmony L0-L2 branch open source code as single framework, followed by a globalised and localised stack with Oniro OS.
