Since its inception, the HarmonyOS version of WeChat has witnessed swift iterations, culminating in a significant update that introduced ten new features. Some users have misconstrued the significance of version numbers, pondering why the HarmonyOS version lags behind the Android version in numeral designation. The WeChat team, leveraging the modular architecture and cross-platform kernel 'Alita,' accomplished the development of core functionalities for the HarmonyOS version in under a year. In stark contrast to the 14-year iterative journey of the Android version, the HarmonyOS version embarked with a robust set of core features, poised for continuous optimization. Software development is an evolutionary process, and user feedback will play a pivotal role in enhancing the user experience of the HarmonyOS version of WeChat.
