# v26.8.1, build 251 (2026-08-xx xx:xx UTC)
- Added a prototype Visual Briefing Assistant that turns documents, data, images, audio, and video into self-contained interactive HTML briefings. When you want to test it, you have to enable this preview feature in your app settings.
- Added organization-configurable defaults and visibility controls for the Visual Briefing Assistant.
- Added a share button for assistants, configurations, and language plugins. It uses the native share dialog on Windows and macOS. For Linux, we added an export option, which stores the plugin archive at a location of your choice. When you work on a translation for a new language, you can now hand your current state to testers or to us with one click.
- Added the option to install plugin archives from your files: use the import button on the plugin page or simply drop an archive onto that page. Assistants, configurations, and language plugins are supported, and plugin archives now have their own file extension `.mwplugin`. Before installing a configuration, AI Studio shows what it sets up: which LLM providers and data sources it adds and where each of them sends your data, plus how many settings it takes control of. A configuration takes effect right away and has no on/off switch, so please install one only when you trust its source. You can remove it again at any time.
- Added a delete button for assistants, configurations, and language plugins you installed or placed yourself. Until now, such a plugin could only be removed from the data directory by hand, which was especially painful for configurations because they have no on/off switch. Before deleting a configuration, AI Studio lists what disappears with it, such as providers, data sources, and settings that return to their default. When you delete the language plugin you had chosen, AI Studio returns to choosing your language automatically. Plugins shipped with AI Studio and plugins deployed by your IT department cannot be deleted.
- Added options for organizations to disable importing, sharing, and exporting plugins, with a separate option for configuration plugins. Organizations can now let people import assistants while keeping configurations to their IT department.
- Added a priority for configuration plugins. Organizations that deploy several configurations can now decide which one wins: a configuration with a higher priority overrides the settings and providers of a lower one. This allows a company-wide base configuration that each department refines for itself.
- Added a way for IT departments to try out a configuration before rolling it out. A configuration placed in the new `.config-tests` directory below the plugins directory acts like one your organization deployed, including the approval of assistant plugins, so a test shows exactly what colleagues will see later. No configuration server is needed for this. AI Studio empties that directory every time it starts, so a test configuration is valid for one session, and the information page reports it while it is active. The Enterprise IT documentation describes the whole procedure.
- 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.
- Added CSV and TSV files to the file types you can attach. AI Studio was already able to read them, but they could not be selected.
- 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.
- 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.
- Fixed files with a wrong file extension being reported as empty. AI Studio now recognizes what a file really is by looking at its content, for example, a PowerPoint presentation that was renamed to `.txt`, and reads it accordingly. It also points out the wrong extension, so you can correct it.
- Fixed files whose content is not text being sent as an empty document. AI Studio now tells you that the file is not readable as text, which usually means it carries a wrong file extension.
- Fixed executable programs with a harmless file extension being read as text. They are now recognized by their content and refused.
- Fixed a single unreadable page of a PDF silently cutting off the rest of the document. The remaining pages are now used, and AI Studio tells you which pages are missing.
- Fixed a single unreadable sheet of a spreadsheet silently dropping all remaining sheets.
- Fixed PDFs, text files, spreadsheets, and presentations requiring Pandoc. Only Word documents, OpenDocument text files, and HTML files need Pandoc, so every other file can now be attached and read without it.
- Fixed attached files that are temporarily unavailable, disappearing from your message without a word. This could happen when a file was stored on a network drive.
- Fixed the file preview showing an empty document when reading the file failed. It now shows what went wrong, so the preview again answers what AI Studio will hand to the AI.
- Fixed problems while reading files being missing from the log file after the first one. This made exactly those issues hard to track down that only appeared later on.
- Fixed reset buttons in assistants. As you may have noticed in the Document Analysis Assistant, resetting it could leave content from the previous analysis visible. Reset buttons now clear previous results completely.
- Fixed dropping files after you closed a dialog that accepts files itself. Such a dialog takes over dropped files while it is open, but never handed that role back when you closed it. Afterward, the chat and the assistants silently ignored dropped files until you switched to another page. Each time you opened such a dialog again, the problem got worse.
- Fixed configuration-managed settings, remaining active after their configuration plugin was removed.
- Fixed settings not returning to your own value after a configuration was removed. When a configuration takes control of a setting, AI Studio now remembers the value you had chosen before and hands it back once no configuration manages that setting anymore. This covers an IT department withdrawing a configuration, deleting one yourself, and an administrator ending a test configuration. When a configuration only suggested a value, and you changed it afterward, your choice stays as it is.
- Fixed the integrated code editor to keep errors and other issues in plugin code visible in the footer while scrolling.
- Fixed the trusted badge so you can now see at a glance which models are trusted. It is shown consistently for self-hosted models and models from trusted providers.
- Fixed approvals for assistant plugins being accepted from any configuration plugin. An approval marks an assistant as safe without a security check, and the app states that your organization approved it. Only configurations your IT department deploys, or that an administrator stages for a test, can do that now; approvals from any other locally placed configuration plugin are ignored and reported in the log.
- Fixed withdrawing a configuration your organization deployed. A configuration that declared itself as locally managed stayed on the device even after the IT department stopped deploying it, and it kept every right of an organization configuration, such as approving assistant plugins. Where a configuration is stored now decides this instead of what the configuration says about itself, so withdrawing one always takes effect. This also applies to a device that was offline while the organization changed its policy: the withdrawal is applied when AI Studio starts again.
- Fixed preview features contributed by several configuration plugins at once. Only the most recent contribution was recognized as coming from your organization, so features enabled by another configuration looked as if you had switched them on yourself. Each configuration is now tracked separately, which lets your organization enable one preview feature company-wide and another one for a single department.
- Fixed which configuration wins when two configuration plugins collide, e.g. by claiming the same plugin ID, by managing the same setting, or by defining the same provider. Previously, this was down to chance, so a local configuration plugin could take over parts of the configuration your IT department deployed. Configurations from your organization now always win, and every ignored attempt is reported in the log.
- Fixed the assistant categories when your organization hides individual assistants. A category heading could stay visible above an empty area, and the Log Viewer could disappear together with the Localization assistant. Each heading now follows the assistants actually shown below it.
- Removed the legacy PowerPoint format (`.ppt`) from the selectable file types. AI Studio has no reader for it, so such a file could be attached but never read. The modern `.pptx` format is not affected.
- Upgraded dependencies to their latest versions to improve security and stability.
