The Tab key and arrow keys can be used to move the focus, and a component can be configured to be focusable. 30- The **\<Column>** and **\<SideBarContainer>** components can be automatically hidden when they are dragged to a width that is less than the minimum width. 31 32For details, see [ArkUI Guide](../application-dev/ui/arkui-overview.md). 33 34 35### Application Framework 36 37- The stage model is introduced in API version 9. It provides mandatory components and running mechanisms for applications. This model makes the development of complex applications simpler and more efficient. 38 - Abilities are provided in the form of classes, making extension easier. 39 - VM instances can be shared within a process, reducing memory usage of applications. 40 - Data objects can be shared within a process, enabling state sharing among multiple modules. 41 - The ability lifecycle is separated from the window display/focus event, and a unified ability lifecycle is used in multiple device forms, facilitating distributed application development. 42 - The ability and UI are separated, RPC capabilities are provided, and abilities can be migrated and collaborated across devices, facilitating distributed application development. 43 44- The ExtensionAbility mechanism is provided. With this mechanism, an application can provide custom functions and content for another application or the system during interaction. For example, an application can be displayed as a widget on the home screen or execute background tasks during off-peak hours. Currently, the following ExtensionAbilities are supported: FormExtensionAbility, WorkSchedulerExtensionAbility, InputMethodExtensionAbility, and AccessibilityExtensionAbility. 45 46- Atomic services can be pre-loaded by package, improving the first-time loading performance. 47 48- The Harmony Shared Package (HSP) is used for sharing of code and resources within an application. 49 50 51For details, see [Application Model Guide](../application-dev/application-models/application-model-composition.md). 52 53 54### Application Package Management 55 56- A default application can be selected. For example, if a user selects an application as the default application when opening a file or URL, that application will be automatically used to open the file or URL of the same type next time. 57 58- The system can grant permissions (such as location and contact permissions) to certain pre-installed applications, such as **Home Screen**, **SystemUI**, and **Settings**, to simplify the authorization process when the device is powered on for the first time. For details, see [Pre-authorizing user_grant Permissions](../application-dev/security/accesstoken-guidelines.md). 59 60- Permission control on pre-installed applications is enhanced. For example, you can configure whether pre-installed applications can reside permanently, use multiple processes, or use ServiceExtensionAbility. For details, see the [Application Privilege Configuration Guide](../device-dev/subsystems/subsys-app-privilege-config-guide.md). 61 62- Application code can be dynamically updated, and quick fix packages are provided for applications to quickly respond to requirements and fix defects. (This capability requires the device vendor to build an application market and provide the distribution capability.) For details, see [Quick Fix Overview](../application-dev/quick-start/quickfix-principles.md). 63 64- HAP-based isolation is provided for .so files, so you can deploy .so files of the same name in different modules. 65 66 67### System Applications 68 69 **Home Screen enhancement** 70 71Users can hold an application icon (currently **Camera** and **Gallery**) on the home screen to add a service widget. 72 73 74 **SystemUI enhancement** 75 76- Control Panel can be opened and exited. 77 78- Notification Panel can be opened and exited. Notifications can be displayed, deleted, group expanded, and group collapsed. Banner notifications can be displayed and hidden. 79 80 81 **Settings enhancement** 82 83- Users can set permissions on the **Privacy** menu. 84 85- The following debugging switches are added to the developer options: layout boundary, transition animation, and transition drawing. 86 87 88 **Photos enhancement** 89 90- The PhotoPicker capability is added. PhotoPicker is a unified entry for users to select images and videos. It enables users to grant only media file permissions to applications when they try to access images and videos. 91 92- The service widget and browsing capabilities are provided for **Albums**. 93 94- Users can edit images, such as cropping and rotating. 95 For details, see [Application Photos](https://gitee.com/openharmony/applications_photos). 96 97 98 **FilePicker** 99 100The FilePicker capability is added. FilePicker is a unified entry for users to select files (except media files). It enables users to grant non-media file permissions to applications when they try to access files other than images and videos. 101 102 103 **Browser** 104 105No built-in browser application is available. You can develop a browser application by following the instructions provided in [Browser Application](https://gitee.com/openharmony/applications_app_samples/tree/samples_3.2_Release/code/BasicFeature/Web/Browser). 106 107### Distributed Technology 108 109Abilities and widgets can be queried, added, refreshed, and deleted across devices. 110 111 112#### DSoftBus 113 114- Files can be transferred over Bluetooth links. Compared with OpenHarmony 3.1, this version provides a 10% increase in the performance of the Bluetooth data transmission channel. 115 116- For each process, two queues are created: a high-priority queue for messages and a low-priority queue for bytes. This ensures that messages can be transmitted in time in the case of byte congestion. 117 118- In addition to raw stream transmission, common stream transmission is provided, which enables DSoftBus to perform encryption and decryption on unencrypted audio and video streams. The caller only needs to transmit raw audio and video streams to DSoftBus, which ensures secure data transmission. 119 120- Transmission links (WLAN/Wi-Fi P2P/Bluetooth BR) can be dynamically selected based on the transmission link supported by the devices and the DSoftBus APIs called (**SendFile**, **SendStream**, **SendMessage**, and **SendBytes**). For example, when stream data needs to be transmitted, a WLAN (5G frequency band) is preferentially selected. If the WLAN is unavailable, another link (for example, Wi-Fi P2P) is selected. 121 122#### Distributed hardware 123 124- The distributed camera allows users to set the location and quality level (which affects the compression ratio and definition of photos). 125 126- The distributed camera supports video recording. 127 128- Users can use the device management native APIs to import account authentication information to the device security authentication system. Devices with the same login account can automatically complete authentication and networking. 129 130 131#### Distributed data management 132 133 **Cross-application data access** 134 135- The proxy mode is used to implement cross-application data access on the same device, avoiding frequent launch of applications that provides the data source. 136 137- Cross-application data access to relational databases and key-value databases on the same device is supported. 138 139 **Local database** 140 141- Key-value databases and relational databases are supported. 142 143- Database files can be encrypted for storage. 144 145- Database damage detection and rebuild are supported. 146 147- Applications can back up and restore databases via clients. 148 149- Key-value databases can be automatically backed up. 150 151- Relational database query for the same application across devices is supported. 152 153- Damage detection and rebuild for metadata databases are supported. 154 155- The key-value database is moved from the unified system sandbox to the application-specific sandbox, minimizing the access permission of application data and improving application data security. 156 157 **Data synchronization** 158 159- Key-value data can be synchronized based on conditions (time segment, time sorting, and synchronization duration). 160 161- When a device goes online, system data is preferentially synchronized, shortening the device wakeup time. 162 163- Cross-device data synchronization in multi-user scenarios is supported. 164 165 **Distributed object**: Objects can be persistent. 166 167 **Sandbox application**: Key-value databases, relational databases, and distributed objects can be persistent. 168 169 170#### Distributed Scheduler 171 172The ability hopping capability is enhanced. The automatic serialization of data structures simplifies application adaptation. The use of distributed objects makes service data migration easier.
