 - Added the BeyondFacts Lab as a prototype. It helps researchers prepare step by step for a challenging appearance, such as a panel discussion, an interview, or a hearing. An introduction explains how to work with the lab, and a chat tells you whether the lab fits your task. Each event gets a preparation of its own, which leads you through seven steps, from the details of the event to what you take away, and shows you which key details are still missing. In each step, a chat guides you with questions, based on your details and a guide on science in public debates. You can add material which every step takes into account, such as papers, the recording of an interview, or a poster. Your preparations are part of your data backups. To try it, open the app settings, allow preview features down to prototype, and enable the BeyondFacts Lab. Thanks to Lara Wüster from the Technical University of Munich (TUM) for the concept and the content of the lab.
 - Added Lucide icons to assistant plugins: name an icon as `lucide:` followed by its name on lucide.dev, such as `lucide:house`. The names of MudBlazor icons keep working, so existing plugins need no change.
+- Added the choice whether AI Studio addresses you formally or informally, in languages which have both forms, such as German with "Sie" and "du". You find the option "Form of address" in the app settings, right below the language. The chats of the BeyondFacts Lab address you the same way.
+- Added the form of address to configuration plugins, so that organizations can preset or lock whether AI Studio addresses their users formally or informally.
 - Improved how well the AI remembers what it looked up in a chat: for its earlier answers, it now knows which web pages it read, which searches it ran, and which sources it used. When you ask a follow-up question, it can read the page again instead of claiming that it never read it.
 - Improved follow-up questions about web pages which a tool found, such as the results of a web search: the Read Web Page tool may read these pages again later in the same chat, also after you restart AI Studio and also when it may otherwise read only addresses which stand in the chat.
+- Improved the texts of AI Studio: we corrected grammar mistakes, missing words, and punctuation in many English texts and improved the wording of some German ones. A few texts which every language showed in English are now translated as well.
 - Changed the icons of AI Studio to Lucide, an open-source icon set. All icons now share one style, and each feature shows the same icon wherever you meet it.
 - Fixed assistant plugins which wrote numbers and dates according to the region settings of your computer. Plugins now show them the same way on every computer: a decimal number such as `12.5` keeps its point, and the `DateTime` helper writes the names of months in English.
