A new programming language for EulerOS and HarmonyOS was announced in September 2021. [9]

On March 27, 2020, openEuler 20.03 LTS version was released in the open source repo as the first Long Term Support (LTS) edition.

openEuler 21.09 version launched with new file system called EulerFS, also a kernel upgrade that is organized similar to classic HarmonyOS and OpenHarmony multi-kernel architecture that carries both RTOS kernel and Linux kernel on October 1, 2021. Also, the operating system supports, UniProton RTOS kernel and kubeOS containerised OS. [10]

EulerOS includes Apache HTTP Server which is known as Apache, as part of its supported tools on the platform. [11]

KunLun Mission Critical Server

EulerOS 2.0, running on the Huawei KunLun Mission Critical Server, was certified in 2019 as conforming to the Single UNIX Specification (UNIX 03); [12] however. the certification expired in September 2022. [13]

EulerOS/KunLun allows replacing central processing unit board modules and memory modules without stopping the OS. Hot swapping of CPU and memory is provided by EulerOS. [14]

Code shared with HarmonyOS and OpenHarmony

EulerOS with openEuler shares technology with Huawei's mobile operating system, HarmonyOS including BiSheng Compiler, distributed DSoftBus technology, OpenHarmony distributed file system (HMDFS), EROFS read-only file system and native HAP file format. Huawei plans to unify additional components between both OSes. [15] [16]

NestOS

In November 2021, NestOS, an operating system based on open source EulerOS was launched. It incorporates the features of EulerOS, enhancing its capabilities in the cloud to cater to specific needs. NestOS, while maintaining the EulerOS ecology, brings its own features for various applications. [17]

In October 2022, the openEuler community updated the NestOS operating system to the new version based on the openEuler 22.09 version that include enhanced features to the system with nestos-assembler container image, optimized Kubernetes, and improvements to its OpenStack system. [18]

Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a bridge to the actual kernel interfaces.

The Android Package with the file extension apk is the file format used by the Android operating system, and a number of other Android-based operating systems for distribution and installation of mobile apps, mobile games and middleware. A file using this format can be built from source code written in either Java or Kotlin.

<span class="mw-page-title-main">Unix-like</span> Operating system that behaves similarly to Unix, e.g. Linux

A Unix-like operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux, FreeBSD and OpenBSD. These systems are often used on servers as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems.

<span class="mw-page-title-main">Unix</span> Family of computer operating systems

Unix is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (BSD), Microsoft (Xenix), Sun Microsystems (SunOS/Solaris), HP/HPE (HP-UX), and IBM (AIX).

Huawei Lite OS is a discontinued lightweight real-time operating system (RTOS) developed by Huawei. It is an open source, POSIX compliant operating system for Internet of things (IoT) devices, released under a three-clause BSD license. Microcontrollers of different architectures such as ARM, x86, and RISC-V are supported by the project. Huawei LiteOS is part of Huawei's '1+8+N' Internet of Things solution, and has been featured in a number of open source development kits and industry offerings.
