 - Improved how your organization's configuration behaves when a configuration plugin is present but cannot be loaded, e.g. because of an error in the plugin. Such a plugin still manages your app, so its settings, providers, data sources, profiles, and chat templates now stay in place instead of being removed.
 - Improved reading large files from slow locations such as network drives. AI Studio now waits considerably longer before it gives up, and it tells you when it does.
 - Improved how Word documents (`.docx`) and OpenDocument text files (`.odt`) are read. AI Studio now reads them itself instead of handing them to Pandoc, so these documents no longer need a Pandoc installation. It reads them section by section, which keeps even large documents responsive, and it now picks up more of the document: the title, the author, headers and footers, footnotes, endnotes, and comments. This was contributed by Nils Kruthoff (`nilskruthoff`), who also wrote the library behind it. Thank you, Nils, for this great contribution.
+- Improved the order of your models. Every list of models is now sorted by provider and name, so all models of one provider stay together. Until now, models appeared in the order they were created, which meant that a model added later always showed up at the end of the list. This was especially confusing when your organization rolled out new models. In the settings, the tables for LLM providers, embeddings, and transcription are now grouped by provider and start collapsed, so even a long list stays easy to survey.
 - Changed how approvals for assistant plugins combine when your organization deploys several configurations. They now add up, so a department can approve additional assistant plugins without repeating the approvals of the company-wide configuration. Previously, the last configuration replaced all earlier approvals, which silently required a new security check for those assistants.
 - Fixed attached files reaching the AI as empty documents when AI Studio could not read them. The AI then answered as if your file had no content, and nothing pointed to a problem. AI Studio now names the cause instead, for example, an unavailable network drive, a file another program is blocking, a protected PDF, or a scanned PDF without a text layer, and it no longer attaches such a file.
 - Fixed files that are open in another program being reported as an unrecognized file type. AI Studio now tells you that the file is currently open elsewhere and asks you to close it. This also works for files on shared network drives, where a colleague might have the file open.
