*Explore new custom colors in Daily Prebuilt.*

## Daily Prebuilt

* 🎨 You can now customize colors in Daily Prebuilt! Pass your own hex codes as a `theme` property to [`join()`](/reference/daily-js/instance-methods/join) or [`createFrame()`](/reference/daily-js/factory-methods/create-frame), or use the new [`setTheme()`](/reference/daily-js/instance-methods/set-theme) method. See the [full guide](/docs/prebuilt/customizing-daily-prebuilt-calls-with-color-themes).
* 🌗 Daily Prebuilt’s default light and dark color themes have been updated (and can now be overridden with the color theming feature).
* 💨 In speaker view, when scrolling the participant bar, remote video feeds will be displayed faster.
* 📞 Added support for the recent-call parameter, when using the `redirect_on_meeting_exit` property.
* 🤫 Meeting owners will now see an option to mute all participants.
* 🎙 Updated the microphone level indicator to reflect when a participant changes their audio device.
* 🐛 Fixed a bug so that the lobby’s name entry screen no longer flashes when a name is cached or provided via a token.
