Google 最新推出了 WearOS 5.1 Developer Preview 版本，提供予 Android Studio 的模拟器中运行，让开发人员测试应用程式。
WearOS 5.1 具体有什么改进还未清楚，不过在 Android Developers 网站上，Google 就特别介绍了两个新改动，分别是 Credential manager support 和 Watch speaker playback。
Credential manager support 是为手表 应用程式提供一个统一的用家认证方案，支援密码, Passkeys 以至 Google Sign-in 等，而用家的认证会储存，可在不同装置上同步。
至于 Watch speaker playback。若果手表设有喇叭播放功能的话，应用程式就可整合 Wear Output Switcher 功能，用家就可以在手表上将媒体播放。
Credential manager support: The Credential Manager API provides a unified authentication solution, supporting sign-in flows using passwords, passkeys, and federated identity (such as Sign In with Google). A user’s credentials are stored in a credential provider, which syncs account information across devices.
Watch speaker playback: On devices that support media playback through the watch speaker, users can select this speaker as their preferred media output option if your app integrates with the Wear Output Switcher.
一般用家现时还未用到 WearOS 5.1，只可以在 Android Studio Emulator 上试用。至于 WearOS 5.1 何时正式推出，相信还有一段时间，毕竟现在只是 Developer Preview，估计可能要明年第二季吧。
