Four video screens on a Daily Prebuilt video call *Introducing [the new Daily Prebuilt](https://www.daily.co/blog/announcing-the-new-daily-prebuilt-for-developers/)* We've shipped two new products since we last wrote! Find the full details about [Daily Prebuilt](https://www.daily.co/blog/announcing-the-new-daily-prebuilt-for-developers/) and [Live Streaming](https://www.daily.co/blog/announcing-daily-live-streaming/) over on [the blog](https://www.daily.co/blog/). Or, keep reading here for other updates! As always, if you have feedback, [we'd love to hear it](https://www.daily.co/contact). *P.s. Join us on Clubhouse! We'll be hosting [recurring conversations](https://twitter.com/trydaily/status/1391582009823166466) about the creator economy. It'd be great if you could make it.* ## daily-js 0.13.0 * 🗺  Added [`'lang-updated'`](/reference/daily-js/events/iframe-ui-events#lang-updated) event that fires when [setDailyLang()](/reference/daily-js/instance-methods/set-daily-lang) is called and changes the call language. The payload includes two values: `lang` and `langSetting`. `lang` is the language currently in effect. `langSetting` is the value the user explicitly specified (e.g. via `setDailyLang()`) that resulted in that language ultimately being set. For example, if you call `setDailyLang('en')`, both your `lang` and your `langSetting` will be `'en'`. If you call `setDailyLang('user')`, where `'user'` is a special language setting that instructs Daily to use the user’s browser’s language preference, then `langSetting` will be `'user'` and `lang` will be the language chosen based on the browser setting: `'en'`, `'fr'`, `'pt'`, or any other Daily-supported language. * 🎫  Shipped [`getMeetingSession()`](/reference/daily-js/instance-methods/get-meeting-session) method that returns the current meeting session id. A [meeting session](/reference/rest-api/meetings) is a set of one or more people in a room together during a specific time window. * ✨  Released [`'meeting-session-updated'`](/reference/daily-js/events/messaging-events#meeting-session-updated) event that fires when the meeting session changes. One meeting session ends and another begins, for example, when you've been sitting alone in a room for 10 minutes. * 🇳🇴  Added Norwegian language support in [Daily Prebuilt](/docs/prebuilt) (language code `"no"`). ## react-native-daily-js 0.10.0 * ⬆️  See above! ## Bugfixes * 🐛  Squashed! If you invoked two or more async methods (like [`getInputDevices()`](/reference/daily-js/instance-methods/get-input-devices), [`room()`](/reference/daily-js/instance-methods/room), [`requestAccess()`](/reference/daily-js/instance-methods/request-access), etc.) within the same millisecond, some of those methods might never have resolved. * 🚨  When a call-ending error happens while using [Daily Prebuilt](/docs/prebuilt), the call iframe will no longer be cleared. Instead, a relevant user-friendly error message (which might be an oxymoron) will be displayed. * ✅  Improved a11y on [Daily Prebuilt](/docs/prebuilt) close button * 🚀  Other [Daily Prebuilt](/docs/prebuilt) performance improvements
