Google 最新推出了 WearOS 5.1 Developer Preview 版本，提供予 Android Studio 的模擬器中運行，讓開發人員測試應用程式。
WearOS 5.1 具體有甚麼改進還未清楚，不過在 Android Developers 網站上，Google 就特別介紹了兩個新改動，分別是 Credential manager support 和 Watch speaker playback。
Credential manager support 是為手錶 應用程式提供一個統一的用家認證方案，支援密碼, Passkeys 以至 Google Sign-in 等，而用家的認證會儲存，可在不同裝置上同步。
至於 Watch speaker playback。若果手錶設有喇叭播放功能的話，應用程式就可整合 Wear Output Switcher 功能，用家就可以在手錶上將媒體播放。
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.
一般用家現時還未用到 WearOS 5.1，只可以在 Android Studio Emulator 上試用。至於 WearOS 5.1 何時正式推出，相信還有一段時間，畢竟現在只是 Developer Preview，估計可能要明年第二季吧。
