OpenHarmony Release Plan

OpenHarmony 3.1 Release Roadmap Overview

Statement: The OpenHarmony roadmap is released every half a year. The actual supported features are subject to the final release.

1. ArkUI

• For the simplified declarative development paradigm, more component capabilities and animation effects are provided, and the canvas drawing capability is supported.
• More interactive input modes: touchscreen, keyboard, and mouse.

2. System Applications

• More system applications, including the Home Screen, System UI, Settings, Camera, Gallery, Call, Contacts, Messages, File Selector, and Input Method.

3. Application Framework

• More ability-related capabilities: Form abilities are provided for widget development. The Feature Ability (FA) and Stage models are provided to support single- and multi-instance component development.
• More bundle management capabilities: Multi-HAP installation and uninstallation are optimized; cross-device application information retrieval is supported; the package structure is optimized.

4. Distributed Feature

• More DSoftBus capabilities for better device interconnection experience: Bluetooth connection, networking, and transmission; P2P connection and networking; file transfer and stream transmission.
• Enhanced hardware collaboration and resource sharing: mirroring, extended projection, and distributed cameras.
• More distributed features: distributed task management, cross-device migration of atomic services and applications, distributed file systems, distributed databases, and distributed data objects.

5. Graphics & Window

• 3D graphics drawing capability based on the EGL/GLES native SDK.
• 3D graphics drawing capability based on the WebGL SDK.
• A new UI animation framework for better UI animation experience: separation between the animation thread and UI thread; new UI animation calculation logic; optimized UI measurement layout drawing logic during animation.
• Split-screen and multi-window display; cross-window content dragging.

6. Media

The following capabilities are added for the standard system:

• Local basic audio/video playback and recording, video hardware codec, and mainstream audio/video codecs and encapsulation formats.
• Basic camera preview, photographing, and recording, and distributed camera preview and photographing.

7. Communication

• Basic call and cellular data capabilities: SIM card, network search, call, SMS, and cellular data.
• More short-distance communication capabilities: Wi-Fi STA/AP/P2P capabilities, active NFC tag read and write capabilities, basic management capabilities of conventional Bluetooth, and basic capabilities of Bluetooth Low Energy (BLE).

8. Security

• A unified key management service to manage the full lifecycle of local keys for system applications and upper-layer services.
• A unified user identity authentication framework to offer unified authentication services, such as PIN authentication, for external systems.
• Access token-based permission management, isolation, and access control architecture.

9. ArkCompiler

• TS/JS compiler and runtime capabilities: eTS, TypeScript 4.13, EcmaScript modules, Concurrent Marking Sweep (GMC) GC, Moving GC, and lightweight Actor/Worker.

• Debugging and tuning: CPU Profiler, row number, column number, breakpoint, error debugging, and attach debugging.

10. Kernel

• File system performance enhancement and security hardening: The flash-friendly file system (F2FS) is supported to provide more flexible space allocation options and underlying space reclamation options. File-level data encryption of F2FS/EXT4 is supported.
• Optimized resource scheduling: Intelligent process grouping, frequency modulation, and work scheduler.

11. IDE & Tools

• Simplified development based on the declarative paradigm UI framework.

• Widget development: Low-code templates are added to support zero-code development of service widgets.

• One-click automatic signature of applications.

• Cross-device application development: API association based on the device capabilities is supported, and RPCIDs can be automatically generated for applications based on the APIs used by developers.

• Optimized debugging: Enhanced logging; event processing, query, and subscription; providing of location information about breakdown, suspension, and kernel restart.

• Test tools and suites for compatibility, including PCS3.1, ACTS3.1, DCTS3.1, HATS3.1, and compatibility certification platform.

• Wukong (an automatic test tool) and SmartPerf (a performance and energy efficiency test tool) delivered with the UI.

• Test frameworks: JavaScript unit test framework, UI test framework, and distributed test framework.
