 - Added a way for IT departments to roll out chat templates that bring their own provider, profile, and workspace. Set the template up in the app, then export it as ready-made Lua code for your configuration plugin.
 - Added settings to the Assistant Builder. There you choose the provider, and with it the model, that the Assistant Builder starts with, the language in which the assistants you build answer, and the minimum confidence level a provider needs. Thanks, Nils Kruthoff (`nilskruthoff`), for this contribution.
 - Added organization-wide management for the defaults of the Assistant Builder. IT departments can preset its provider, the language in which the assistants built with it answer, and the minimum confidence level, either fixed or as a default which users may change.
+- Added support for PowerPoint templates to the Slide Assistant. When you choose a presentation or template (.pptx or .potx), for example the one of your organization, the assistant plans every slide for one of its layouts, and you can save the slides as a PowerPoint file in its design. You can also choose which of its layouts the assistant uses for kinds of slides, such as chapters or comparisons, add framing slides such as a table of contents or an imprint, and keep slides of your file. Without a template, you get an outline, as before. In both cases, you can now name the occasion of your presentation, such as a lecture or a report to management, and the number of bullet points you set is a maximum per slide. You can also attach pictures which the slides must show, let the assistant choose pictures and icons by their names from a folder, such as the picture library of your organization, and keep empty picture placeholders to insert pictures of your own later. Thanks, Sabrina (`Sabrina-devops`), for this contribution.

 - Improved the Read Web Page tool. When you have not allowed the AI to choose web addresses freely, the tool now refuses every address that does not appear in your chat or in what the tools returned, instead of only asking the AI not to read it.
 - Improved the installation on macOS: AI Studio is now signed and checked by Apple, so it opens like any other app. You no longer need the Terminal.
 - Improved the installation on Windows: AI Studio is now signed, so Windows shows who published it. For a while, Windows may still ask you to confirm the installation until it knows the app better.

 - Improved images in chats and assistants. AI Studio now scales large photos down before it sends them to the AI, so they no longer fail at providers with size limits, such as Anthropic. Photos also no longer carry their location data along.
 - Improved attaching images to chats and assistants. AI Studio now converts BMP and TIFF images into a format the AI understands, and it tells you right away when it cannot give an image to the AI, for example, in HEIC or SVG format.
 - Improved the jump to the right page for the sources of your own documents (RAG): when you open PDFs with PdfCraft, the document now opens directly at the page where the passage was found, on Windows, macOS, and Linux. Each source opens in a PdfCraft window of its own.
+- Improved assistants which write long answers, such as the Slide Assistant. While the AI writes, AI Studio now spends less time updating the screen. The Slide Assistant also tells you what the AI is doing while it plans, for example, which slide it is writing.
 - Changed the banner on the start page to a fresh design that shows what AI Studio can do today.
 - Changed when a chat you add to a workspace in the workspace list appears there. Like any other new chat, it now appears once there is something to keep, for example, your first message, instead of right away.
+- Changed the name of the Slide Planner Assistant to Slide Assistant. With a PowerPoint template, it now creates the slides themselves, not just a plan for them.
 - Fixed a warning about the confidence level that stayed in the dialog for adding a local data source, even after you chose an embedding provider that meets it. The dialog now checks again whenever you change either of them, so a warning also appears when you switch to a provider that falls short.
 - Fixed the list of data sources squeezing their names into a very narrow column when you opened it from a chat or from the background embeddings page, so the names were hard to read.
 - Fixed two confidence levels sharing the same name in the German user interface. Moderate is called "Mäßig" again, and Medium stays "Mittel".
