In September 2025, the OpenHarmony Technology Conference took place in Changsha. During this event, the OpenAtom OpenHarmony Project Group officially unveiled the OpenHarmony 6.0 Release version. This iteration marks substantial enhancements in technical capabilities and brings about remarkable breakthroughs across multiple crucial domains.

At the application development front, the ArkUI component capabilities have undergone refinement. A new default extension function has been introduced for the component background safe area, aiming to elevate the immersive development experience. Moreover, the ArkTS language now boasts support for defining FastBuffer objects and dynamically generating XML files, which streamlines the development workflow.

When it comes to media capabilities, a groundbreaking low - latency ear return function has been incorporated, enabling real - time audio transmission to wired headphones. For live - streaming scenarios, high - definition AEC recording capabilities have been rolled out to optimize the audio - video synchronization effects.

In the realm of the graphics system, new functions have been introduced. These include automatic spacing adjustment between Chinese and Western characters and independent text color settings, which significantly enhance the expressiveness of multi - language layouts. Additionally, image encoding now supports HDR - quality ASTC encoding, resulting in more precise and detailed image displays.

Regarding system security, the certificate management module has been fortified with an interface for invoking the user authorization screen. It also supports bidirectional TLS authentication and document signing functions. The encryption and decryption algorithm library has extended its support to include the DES algorithm and achieved mutual conversion of SM2 signature data formats, thereby strengthening the overall security protection capabilities.

Furthermore, the new version introduces a white - box performance testing framework. This framework is capable of accurately measuring key performance indicators, such as CPU usage and application cold start time, for specific code segments. The UI testing framework has also been upgraded to support finding and simulating operations on controls in multi - screen environments, enhancing testing efficiency and coverage in complex scenarios.
