 - Added Requesty as a new LLM provider for chats, embeddings, and transcriptions. Requesty is an AI gateway from the United Kingdom that gives you models from many providers with a single API key. Because where your data is processed depends on the model you choose, you set its trust level yourself. Thanks, Thibault Jaigu (`Thibaultjaigu`), for this first contribution.
 - Added [llmman](https://github.com/llmmanorg/llmman) as a new option for the models you host yourself. llmman runs open models on your own computer or server, and AI Studio can use them for chats, embeddings, and transcriptions. Thanks, Eric Curtin (`ericcurtin`), for this first contribution.
 - Added support for Mistral Large 4.
+- Added backups of all your data. Under Data Backup & Restore, on the information page and in the settings, you save your chats, settings, plugins, and the index of your data sources into a single file, for example, to take everything to a new computer. Restoring such a backup replaces your data when AI Studio restarts, or you add only its chats to the ones you have. API keys and passwords never go into a backup, and after a restore, AI Studio tells you where to enter them again. Thanks, Jens Erler (`j-erler`), for this contribution.
+- Added organization-wide management for backups. IT departments can prevent users from backing up their data or from restoring a backup. A backup leaves out what the configurations of your organization bring along, such as their providers and plugins, so nothing appears twice after a restore.
+- Added an overview of the data folders of AI Studio to the information page, for when you back up your computer with a tool of your own. It shows where the folders are and which of their contents belong into a backup. AI Studio now stores the locations of its own files, such as transcripts, relative to its data folder, so such a copy also works on a computer with another user name.
 - 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.

 - 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 two confidence levels sharing the same name in the German user interface. Moderate is called "Mäßig" again, and Medium stays "Mittel".
 - Fixed renaming an external data source (ERI server) leaving its secret behind under the old name in the keychain of your operating system.
+- Fixed the ERI server assistant deleting files in a folder you no longer used. When it updates a server, it deletes the files it created before, and after you chose another folder for the server, it also deleted them in the old one. It now only deletes files within the folder you chose.
 - Fixed the Search Confluence tool missing pages that the search of your Confluence wiki finds. The tool now searches the same way as the search box of your wiki.
 - Fixed AI Studio starting only partly when the configuration of your organization took a while to apply. The plugins late in line never started, so the app stayed in English instead of your language, and the configuration of your organization was missing, together with its models and its welcome text. Now every plugin gets its own time to start, and a slow one no longer holds up the others.
 - Fixed AI Studio deleting the providers, chat templates, and profiles of your organization, including their API keys, when the configuration of your organization did not start in time. They now stay in place until the configuration starts again.

 - Fixed answers breaking off with an error message from self-hosted AI servers such as vLLM when the AI made up the name of a tool or sent broken details for one. AI Studio now tells the AI that its tool call was invalid, and the AI can finish its answer.
 - Fixed OpenAI models using about 4,300 more tokens than necessary with every request. AI Studio offered them OpenAI's own web search in the background, even when you had not selected a web search. To let a model search the web, select the Web Search tool below the message field.
 - Fixed AI Studio sometimes rebuilding the index of a data source from scratch when the configuration of your organization was applied while the data source was being updated.
-- Fixed AI Studio is continuing to update the index of a data source with the old settings after you, or the configuration of your organization, changed its embedding provider or the expert settings of the data source, which could take hours for nothing. AI Studio now stops right away and starts over with the new settings.
-- Fixed AI Studio is continuing to send the content of a data source to an embedding provider after you deleted that provider, or after a confidence level changed so that the provider may no longer read the data source. AI Studio now stops right away.
-- Fixed data sources are staying unavailable after the configuration of your organization changed their embedding provider, until one of their documents changed, or you restarted AI Studio. When AI Studio updates your data sources automatically, it now rebuilds their index right away.

+- Fixed AI Studio deleting the index of a local data source when it could not reach its folder or file, for example, because the drive was not connected. Once the folder was back, AI Studio indexed everything again, which could take hours. AI Studio now keeps the index and tells you that it cannot reach the folder. The same applies to subfolders you are not allowed to open.
+- Fixed AI Studio rebuilding the index of a data source from scratch without asking you when part of the index was missing on your computer. Since this sends every document to your embedding provider once more, AI Studio now tells you about the missing index and offers to repair the data source.
 - Fixed justified texts being hyphenated by the rules of English even when AI Studio shows another language, such as German. Screen readers now also know which language AI Studio uses.
 - Fixed the log file of AI Studio showing the wrong time for some entries when AI Studio was busy. Each entry now shows when it actually happened.
 - Fixed AI Studio pausing for a moment while it opened the local index of a data source, such as a mailbox. Other work, for example applying the configuration of your organization, had to wait until then.
