Graphics Accelerate Kit adds the pre-launch feature to improve the launch experience of game apps. Notification Kit further enhances the notification management capability and display effect, and supports the ability to display the notification settings screen of an app in semi-modal mode. In addition, the Chromium kernel of ArkWeb has been upgraded from version 132 to version 144. For details, see New and Enhanced Features of the OS platform.
DevEco Studio capabilities have been further enhanced: API 26.0.0 projects are now supported; modules can be loaded on demand to improve code indexing efficiency; the Code Scanner tool has been added to check for resource leaks in an entire project; the UI effects of an app can be previewed at eight typical breakpoints simultaneously; a car device simulator has been added, which can be remotely controlled; devices can be projected to DevEco Studio for use; dump files generated upon app crashes can be parsed, and abnormal stacks can be displayed.
