HarmonyOS

Huawei announce new OpenHarmony 1.1.0 LTS, features, modification, next year’s schedule and more

Huawei is aiming to develop a distributed OS that can satisfy the user’s need of  low latency and strong security.” In this line, the company released the HarmonyOS, a lightweight compact operating system with powerful functionality.

Initially, it was released for smart IoT devices such as smartwatches, smart screens, smart cars, and more. The company is continually exploring this OS so it can fit in today’s scenarios where people expect a holistic intelligent experience across all devices.

To accomplish this goal, Huawei recently announced the OpenHarmony 1.1.0 LTS version, which is far better than the previous 1.1 LTS. This new version will come with an AI subsystem, power management subsystem, pan-Sensor subsystem, Upgrade subsystems, unified AI engine framework, and more.

LTS Brief Intro:

To be mentioned, Long-term support (LTS) is a product lifecycle management policy in which a stable release of computer software is maintained for a longer period of time than the standard edition.

The term is typically reserved for open-source software, where it describes a software edition that is supported for months or years longer than the software’s standard edition.

It’s worth bringing up that Open Harmony is an open-source project handle by the OpenAtom Foundation, and is positioned as an open-source distributed operating system for all scenarios.

This latest version ensures the pyramidal transferability rebuilding of the liteOS-Mkernal. Adding to that the driver subsystem enhances the driver models of Wi-Fi, Sensor, Input, and Display, and targets the graphics subsystem to UI capabilities, JS framework performance, and memory optimization.

Furthermore, Huawei also revealed the schedule for the OpenHarmony version, which is likely to start the next year.

Let’s take a detailed look at the changes that come with the new 1.1.0 LTS version of OpenHarmony:
