+OpenHarmony 5.0.0 Release continuously improves its standard system capabilities. It provides the following enhancements over OpenHarmony 4.1 Release:
 
-The application framework provides more lifecycle management capabilities and child process capabilities, allowing for more refined task scheduling and management during runtime. ArkUI further opens up the rendering capability of custom nodes. The bundle manager improves the efficiency of application packaging and enriches the operable scenarios when end users use applications (such as creating application clones and home screen shortcuts). Distributed data management is further enhanced for higher security while ensuring proper data sharing. Module adaptation to the sendable mechanism is also enhanced. The file manager further improves the picker capability to properly control and use file resources. The media playback and recording capabilities are further enhanced, with new support for multiple audio, video, and image encoding formats, along with more refined playback control operations. The camera provides more powerful capabilities, enriching the scenarios for end users to take photos.
+The application framework has introduced more lifecycle management capabilities and child process related capabilities. It can now conduct more refined scheduling and management of tasks at application runtime. The lifecycle management capabilities have been refined, and the application launching and redirection capabilities have been improved. ArkUI has further opened up the rendering capabilities of custom nodes and improved the components' capability to call through C APIs. Bundle management has improved the efficiency of application packaging and enriched the operational scenarios for end users when using applications (such as creating application clones and home screen shortcuts). The connection capabilities and specifications of DSoftBus have been further enhanced. The distributed data management capabilities have been further strengthened. While ensuring the rational sharing of data, security has been enhanced. The Sendable mechanism adaptation capabilities of other modules have also been improved. File management has further improved the Picker's capabilities, achieving rational control and use of file resources. Media capabilities in audio and video playback and recording have been further enhanced. Support has been added for multiple audio, video, and image encoding formats. More detailed playback control operations are now supported. The camera provides more powerful capabilities, enriching the scenarios for end users to take photos. The framework capabilities, video encoding and decoding capabilities, and audio and video application capabilities have been improved. The media library has enriched the usage scenarios and provides a better user experience.

+- Screen unlock events triggered by swiping up from the bottom can be reported.
+
+- Events from irregularly shaped windows can be reported. Mouse events in the transparent area of an irregularly shaped window are transparently transmitted, but those in the non-transparent area are blocked.
+
+- The following knuckle-based interaction events are supported: rendering paths traced by knuckle movements, animating these knuckle paths, capturing screenshots by making circular gestures with a knuckle, performing extended screen captures with an 'S' gesture, and starting screen recording through a double-tap gesture using two knuckles.
+
+- The Smart Button is provided, enhancing the existing fingerprint button capability.
+
+- Infrared capabilities are supported, providing external frequency data to the caller device.
+
+- The mouse and touchpad can adapt to window rotation. In the event distribution module, the mouse coordinates are rotated and distributed to the correct window based on the window rotation information synchronized by the window.
+
+- The capability to launch system applications by pressing combination keys is supported. When the screen is off, pressing the combination keys does not launch the screenshot application. When the screen is locked, you must long press the combination keys to launch the screenshot application. Different applications are launched when you press or long press the same key. The capability of shielding combination keys through interfaces is also supported.
+
+- The stylus can be double-tapped to start the shorthand. When the screen is off, double-tapping of the stylus can be correctly identified.
+
+- The touchpad display-control ratio curve model is adapted. Based on this model, the multimodal input data preprocessing module processes the received touchpad single-point touch data.
+
+- The stylus can be used to continuously take snippets. Users can use the stylus for input and use the touchscreen for touch interaction. The annotation window responds to the stylus input, and the application window at the bottom responds to the touchscreen operations.
+
+- The pointer position information can be displayed and dynamically enabled or disabled. The number of touch pointers, touch position, and moving speed can be displayed.
+
+- Applications can listen for events from the power button and volume button. When the call application receives an event from the volume button or power button, it mutes the ringtone of incoming calls.
+
+- The performance benchmarking tool is provided to record key service logs. The demonID is used to distinguish service logs. Fault benchmarking is supplemented or added to ensure that all faults in the domain have corresponding event benchmarks, improving the DFX capability.
+
+- KeyCode is added to support custom common events for screen reading.
