Merge branch 'main' into chunk-data
Resolved 29 conflicting files. The notable decisions: Confidence: main's tool-calling gate (RequiredProviderConfidence) and this branch's local-RAG gate (DataConfidenceLevel) turned out to be the same rule on the same axis, so they are now one field. Both tool results and data sources raise it through RequireProviderConfidence(). The gate checks the level strictly and no longer exempts providers trusted by configuration: TrustedProviderIds is documented as applying to data-source security checks only, and organizations set confidence through DataConfidence .CustomConfidenceScheme instead. The security axis (DataSecurity, ERI, IsTrustedForDataSourceSecurityChecks) is unchanged. Provider creation: main's CreateProvider signature won (hfEndpointKind, capabilityOverrides, no model parameter); tokenizerPath was added to it and is set for every provider, including the new Hetzner, IONOS and LiteLLM. Provider and EmbeddingProvider combine the record parameters, Lua parsing and Lua serialization of both sides. File types: main's hierarchy (ODT leaf, WORD parent, PowerPoint without the legacy .ppt, TABULAR instead of DELIMITED_TABLE) plus this branch's SPREADSHEET parent with ODS and the xlsm/xlsb/xla/xlam extensions, which the runtime already reads. Both sides had added a conflicting HTML filter; the reading family keeps the name, and the export path uses a narrow HTML_DOCUMENT, following the existing LATEX/TEX split. Runtime: main's file_data.rs is the base, including the prompt-injection sanitizer and the extraction routes. Token counting and chunk segmentation moved into take_released, so they act on the text the filter has released rather than on text it is still holding. A failed count is logged and left out instead of ending the extraction, because the app counts such a segment itself. Data sources: the participating-provider checks of this branch are kept, and main's GetAllowedDataSources overload now builds on them. DirectChatService resolves the launched chat's data source options before the check, so filter and chat see the same options. .NET and Rust both build clean; I18N regenerated to 4060 keys.

<description>
|
||||
<ul>
|
||||
<li>Added protection against prompt injection. Documents, web pages, and retrieved content can carry instructions written for the AI rather than for you, for example, text telling it to ignore its rules or to hand over its instructions. AI Studio now always removes such passages before the content reaches a model, while the rest of your document stays intact and usable. When something was removed, AI Studio tells you and can show you which passages it took out. You can turn off the detailed dialog in the app settings. For IT departments: the new setting <code>DataApp.ShowPromptInjectionAlert</code> lets you configure the detailed dialog for your organization. Many thanks to Sabrina <code>Sabrina-devops</code> for implementing this feature and to Simon <code>SimonBpunkt</code> for his work on the detection patterns and their translations.</li>
|
||||
<li>Added configurable direct-chat launchers for assistant plugins. Plugin authors and the Assistant Builder can now open a chat with a chosen workspace, provider, profile, chat template, and data sources, while unavailable or unauthorized selections are reported before a chat is created.</li>
|
||||
<li>Added the option to load the assistant description from a file in the Assistant Builder.</li>
|
||||
<li>Added provider logos throughout AI Studio, making models easier to recognize at a glance. Configuration plugins can now give managed LLM, transcription, and embedding providers their own project icon with the optional <code>IconPath</code> field.</li>
|
||||
<li>Added the option for IT departments to enable assistant plugins they rolled out. Approving an assistant only stated that it is safe, so everybody still had to switch it on themselves. An approval can now also enable the assistant, either as a default, which you may switch off again, or in a way your IT department keeps in place. The plugin page and the security card of the assistant tell you which of the two applies.</li>
|
||||
<li>Added knowledge about the latest AI models. AI Studio now recognizes Qwen 3.8 Flash, GLM-5.3 Flash, Meta's Muse Glimmer, NVIDIA's Nemotron 3.5, Tencent's Hunyuan Hy3, Grok 4, Claude Opus 5 and Sonnet 5, and Gemini 3.6 and 3.7. It knows what each of them is capable of, so images, videos, tool usage, and reasoning are available right away instead of staying hidden.</li>
|
||||
<li>Added the IONOS AI Model Hub as a provider for chats and embeddings. It runs open-source models in Germany, is subject to the GDPR, and IONOS states that your data is not used for training.</li>
|
||||
<li>Added LiteLLM as a new LLM provider for chats, embeddings, and speech-to-text. LiteLLM is an AI gateway you run yourself in front of models from many providers. Because your gateway decides where your data goes, you set its trust level yourself. Thanks Prodman Devokadev (<code>prodmanpd</code>) for this first contribution.</li>
|
||||
<li>Added speech-to-text for Helmholtz Blablador and GroqCloud, and embeddings for GWDG SAIA. These providers offer these services now, so you can select them when you dictate a message or when you set up a data source.</li>
|
||||
<li>Added embeddings and speech-to-text for Hugging Face, so you can now use it to prepare your own documents for retrieval and to dictate your messages. Hugging Face offers both through a few of its inference providers only, which is why you get a shorter list to choose from there than you do for chatting.</li>
|
||||
<li>Added a model list for Hugging Face. Until now, you had to type the name of the model yourself and hope you got it right, down to its capitalization. AI Studio now loads the models your chosen inference provider actually offers, so you pick one from a list and cannot end up with a model that the provider does not serve.</li>
|
||||
<li>Added more file formats for exporting an AI answer. The export button used to offer Microsoft Word only; it is now a menu which also writes OpenDocument Text for LibreOffice, LaTeX, Markdown, and a webpage. When an answer contains tables, each of them can be saved on its own as a spreadsheet file, named after the heading above it and ready to open in Excel or LibreOffice Calc. This works in the chat and for the results of every assistant. Many thanks to Nils Kruthoff (<code>nilskruthoff</code>) for this contribution.</li>
|
||||
<li>Added a choice of file format to the Batch Processing assistant. When it writes one result file per document, those files were always Markdown; you can now pick Microsoft Word, OpenDocument Text, LaTeX, or a webpage instead. For IT departments: the new setting <code>DataBatchProcessing.ResultFileFormat</code> lets you configure the format for your organization.</li>
|
||||
<li>Improved the safety of plugin symbols: AI Studio now shows the symbol of a plugin in isolation, so nothing inside a symbol can reach the rest of the app.</li>
|
||||
<li>Improved how much memory AI Studio needs. Working with large documents used to grow the app to several gigabytes, and on macOS that memory was never handed back. AI Studio now stays at a fraction of that and returns memory to your system. This matters most on devices with little memory, such as a Raspberry Pi.</li>
|
||||
<li>Improved the preview for large documents. It now shows you the beginning of your document instead of loading all of it, so the dialog opens right away. Your complete document still goes to the AI.</li>
|
||||
<li>Improved how AI Studio deals with rare internal hiccups. When the app window reloads, or when it briefly loses the connection to its own user interface, work which was still running in the background is now ended properly instead of leaving errors behind.</li>
|
||||
<li>Improved how IT departments roll plugins out. A configuration server can deliver any kind of plugin, not only configurations: one archive may carry assistant plugins and further types alongside a configuration, each in its own folder. The folder for staging a test behaves the same way, so a test can mirror the later rollout exactly. The Enterprise IT documentation describes the whole procedure.</li>
|
||||
<li>Improved which models you get to choose from when chatting: models you cannot chat with are now hidden. This is most noticeable with a gateway such as LiteLLM, which offers you everything its providers have, including video, live speech, and audio models.</li>
|
||||
<li>Changed the model list of GroqCloud. Models which cannot be used for chatting, such as the speech and the safety models, no longer show up among the chat models. The speech models now appear where they belong, in the settings for speech-to-text.</li>
|
||||
<li>Changed how plugins your organization rolled out are protected. They can no longer be deleted or edited in AI Studio, which already applied to sharing and replacing them. This also covers plugins staged for a test: such a test now ends by restarting AI Studio or by removing the staged files, instead of through the plugin page.</li>
|
||||
<li>Fixed the Hugging Face provider, which had stopped working. Hugging Face changed the way requests are addressed, and AI Studio still used the old way, so chatting failed with a puzzling error about the message format. Chatting works again, and you can now reach far more inference providers, among them Z.ai, Groq, Cohere, DeepInfra, and Baseten. You may also leave the choice to Hugging Face and let it pick the fastest or the cheapest provider for you, which switches to another one when your first choice is unavailable. Should a provider not offer the model you selected, AI Studio now tells you so in plain words instead of reporting a technical problem. The providers Hugging Face no longer run are gone from the list; if you had picked one of them, AI Studio asks you to choose again.</li>
|
||||
<li>Fixed the abilities shown for Google's Gemma models. AI Studio did not recognize them at all and treated every one of them as a text-only model, so images, reasoning, and tool usage stayed hidden even though Gemma 4 handles all three.</li>
|
||||
<li>Fixed assistants created by the Assistant Builder being named after an internal placeholder, such as "Model decides", when you left the display name empty. The model now picks a fitting name instead.</li>
|
||||
<li>Fixed AI Studio reading a document to the end even after you closed its preview. Closing the dialog now stops that work immediately.</li>
|
||||
<li>Fixed AI Studio holding on to finished chats, presentation images, and plugin data. It releases them now, so memory no longer grows the longer you keep the app running.</li>
|
||||
<li>Fixed assistants handing an outdated result to the chat. When you sent several results without opening the chat in between, you now receive the one you sent last.</li>
|
||||
<li>Fixed rare issues when multiple configurations provided introduction texts or mandatory information under the same ID.</li>
|
||||
<li>Fixed the description of the global voice recording shortcut always appearing in English. On Linux, your desktop asks you to confirm such a shortcut and shows this description; it now appears in your language.</li>
|
||||
<li>Fixed the code editor being offered for assistant plugins your organization manages. Editing one would have withdrawn the approval of your IT department and demanded a fresh security audit.</li>
|
||||
<li>Fixed assistant plugins your organization deployed alongside a configuration not being recognized as centrally managed unless they declared it themselves.</li>
|
||||
<li>Fixed a misleading warning in the log when an organization deployed an archive that carries no configuration of its own.</li>
|
||||
<li>Fixed AI Studio underrating what many models can do. Newer Claude, Gemini, Grok, DeepSeek, and Qwen models were missing abilities they actually have, such as image input or tool usage. This was most noticeable with OpenRouter, where nearly every model was affected. AI Studio now derives these abilities from the same source for all providers, so a model offers the same capabilities no matter which way you reach it.</li>
|
||||
<li>Fixed the abilities shown for the models offered by Mistral. Mistral names its models after their release date, so almost every one of them was missing image input or reasoning: picking Mistral Large from the list gave you a different set of abilities than picking the very same model by its full name. AI Studio now goes by the release date and gets all of them right, including the Ministral models and the open-source models Mistral hosts, such as GLM.</li>
|
||||
<li>Fixed AI Studio staying silent about why dictating or embedding failed. When a provider explains what went wrong, you now get to read it instead of a general note that something did not work. If a provider cannot handle the audio format AI Studio sends, it says so and suggests contacting that provider.</li>

<release type="stable" version="26.8.1" date="2026-08-19">
|
||||
<description>
|
||||
<ul>
|
||||
<li>Added Hetzner's experimental inference API as an LLM provider. It runs open-source models in the EU and supports text and image chats through its OpenAI-compatible API.</li>
|
||||
<li>Added support for the new open source models DeepSeek V4 Flash and Pro, GLM 5.2, Kimi K2.7 Code and K3, as well as Qwen 3.6 and 3.8.</li>
|
||||
<li>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.</li>
|
||||
<li>Added organization-configurable defaults and visibility controls for the Visual Briefing Assistant.</li>
|
||||
<li>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.</li>
|
||||
<li>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 <code>.mwplugin</code>. 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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>Added the Batch Processing Assistant: process all documents of a folder in one run. Each document is sent to the AI along with your instructions – either a free prompt, one of your document analysis policies, or instructions you import from a file. You choose whether each answer is stored as its own Markdown file or whether all answers are collected in one CSV results table, which you can name yourself. Every run writes a log that lists each document with its processing time, the model, the status, and the reason for any error. When you start another run on the same output folder, we ask whether you want to continue it: documents that failed or are missing from the log are processed again, which is helpful after a crash or when documents exceeded the context window of your model. A single failing document never stops the run, and you can cancel at any time. The assistant was contributed by Jens Erler (<code>j-erler</code>) and marks his first contribution to AI Studio. Thank you, Jens, for this wonderful and useful contribution.</li>
|
||||
<li>Added a way for IT departments to try out a configuration before rolling it out. A configuration placed in the new <code>.config-tests</code> 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.</li>
|
||||
<li>Added providers for which you bring your own API key. Until now, a provider your organization configured had to come with a shared API key, which meant your IT department needed one key for everybody. Such a provider can now be handed out without a key, so that everyone signs in with their own, for example, a personal OpenAI or Anthropic account. This works for chat, embedding, and transcription providers alike. The provider stays managed by your organization: the host, the model, the instance name, and everything else remain fixed, and the only thing you can edit is the API key. In the settings, these providers carry a key icon instead of the usual lock, so you can see at a glance where you have to add your key; for embedding providers, the test button stays available, so you can check your key right after entering it. Your key is stored on your device in the operating system's credential store, and it stays there even when your organization withdraws the provider later, so it is still in place should the same provider return. For IT departments: the new <code>AllowUserProvidedAPIKey</code> option does this, and it works for <code>LLM_PROVIDERS</code>, <code>EMBEDDING_PROVIDERS</code>, and <code>TRANSCRIPTION_PROVIDERS</code> alike.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>Improved how Word documents (<code>.docx</code>) and OpenDocument files (<code>.odt</code>) 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 (<code>nilskruthoff</code>), who also wrote the library behind it. Thank you, Nils, for this great contribution.</li>
|
||||
<li>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.</li>
|
||||
<li>Improved how you access log files from the information page: you can now open their locations in the system file manager or jump directly to the Log Viewer Assistant.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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 <code>.txt</code>, and reads it accordingly. It also points out the wrong extension, so you can correct it.</li>
|
||||
<li>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.</li>
|
||||
<li>Fixed executable programs with a harmless file extension being read as text. They are now recognized by their content and refused.</li>
|
||||
<li>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.</li>
|
||||
<li>Fixed a single unreadable sheet of a spreadsheet silently dropping all remaining sheets.</li>
|
||||
<li>Fixed PDFs, text files, spreadsheets, and presentations requiring Pandoc. Only HTML files need Pandoc now, so every other file can be attached and read without it.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>Fixed the file preview looking like an empty file while AI Studio was still reading it. Larger documents and PDFs need a moment to be read, and until now that moment looked like a file without any content. The preview now says that it is still loading and shows the content as soon as it is ready.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>Fixed configuration-managed settings, remaining active after their configuration plugin was removed.</li>
|
||||
<li>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.</li>
|
||||
<li>Fixed the integrated code editor to keep errors and other issues in plugin code visible in the footer while scrolling.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
<li>Fixed a removed API key staying in the operating system's credential store. When you cleared the API key of a provider, the previous key remained stored and was still used. It is now removed together with your change.</li>
|
||||
<li>Fixed AI Studio installing a second copy of itself next to an existing installation. Its updater always installs into your personal user folder, so an installation elsewhere, such as one your IT department rolled out, was never replaced. AI Studio now recognizes those installations and leaves them alone. The information page tells you which case applies to yours. For IT departments: automatic updates can now stay enabled for everybody, and the Enterprise IT documentation explains the rest.</li>
|
||||
<li>Fixed installing an assistant on Linux when AI Studio runs as a Flatpak. The Assistant Builder was able to create an assistant, but installing it always ended with an unexpected error.</li>
|
||||
<li>Fixed the plugins page and the assistants page reloading again and again on Linux, which started as soon as an assistant was installed. Both pages kept flickering, and nothing on them could be used anymore until you left for another page.</li>
|
||||
<li>Removed the legacy PowerPoint format (<code>.ppt</code>) from the selectable file types. AI Studio has no reader for it, so such a file could be attached but never read. The modern <code>.pptx</code> format is not affected.</li>
|
||||
<li>Upgraded dependencies to their latest versions to improve security and stability.</li>

|
||||
<p>Update</p>
|
||||
<ul>
|
||||
<li>Added support for OpenAI GPT-5.6 Sol, Terra, and Luna; Anthropic Claude Fable 5 and Mythos 5; and Google Gemini 3 Flash, Gemini 3.1 Flash-Lite, Gemini 3.1 Pro, and Gemini 3.5 Flash.</li>
|
||||
<li>Added support for OpenDocument presentations (<code>.odp</code>) when attaching and reading presentation files.</li>
|
||||
<li>Added a log viewer assistant that shows AI Studio log files in a read-only view with search, log filters, highlighting, and auto-refresh.</li>
|
||||
<li>Added audio and video transcription for chats and assistants. AI Studio now prepares supported media locally, sends only normalized audio to the configured transcription provider, and attaches the resulting transcript instead of the original media.</li>
|
||||
<li>Added AI-assisted editing and revision for assistants created with the Assistant Builder. Thanks, Nils Kruthoff (<code>nilskruthoff</code>), for this contribution.</li>
|
||||
<li>Added options to view and edit the code of AI-generated assistants and to delete your own generated assistants. Thanks, Nils Kruthoff (<code>nilskruthoff</code>), for this contribution.</li>
|
||||
<li>Added enterprise configuration options to hide the last changelog and vision panels on the welcome page. Thanks, Dominic Neuburg (<code>donework</code>), for the contribution.</li>
|
||||
<li>Improved the "My Tasks Assistant": you can now provide one or more documents in addition to text or use documents alone when asking to identify tasks.</li>
|
||||
<li>Improved presentation imports so AI Studio can include speaker notes, slide comments, and presentation metadata in the extracted content.</li>
|
||||
<li>Improved update guidance for Flatpak installations and added an enterprise option that lets organizations manage updates entirely through their IT department.</li>
|
||||
<li>Improved secure API-key storage diagnostics on Linux. AI Studio now provides specific guidance when the default password collection is missing or locked, a password-manager prompt is dismissed, or no compatible Secret Service is available.</li>
|
||||
<li>Improved the file dialogs to prevent opening multiple times when you click "Open" or "Save" multiple times in a row.</li>
|
||||
<li>Improved assistant plugins so they clearly indicate when content from a document has been loaded and clear the indicator when the assistant is reset.</li>
|
||||
<li>Improved the Assistant Builder security check so it can use the selected provider when no dedicated security audit agent provider is configured.</li>
|
||||
<li>Fixed an issue that could leave AI Studio unresponsive after waking the computer from sleep. Yes, we know this was an annoying bug, and we apologize for the inconvenience.</li>
|
||||
<li>Fixed connections to internal HTTPS services and enterprise configuration servers that use organization-provided root certificates on Linux.</li>
|
||||
<li>Fixed enterprise configuration plugins from Windows-created ZIP files may not load correctly on Linux when the ZIP contained plugin files inside a folder.</li>
|
||||
<li>Fixed the voice recording shortcut on Linux so it works globally on supported desktops and while AI Studio is focused on other Linux desktops.</li>
|
||||
<li>Fixed voice recording and transcription on Linux.</li>
|
||||
<li>Fixed copied content from AI Studio not remaining available on the clipboard on Linux.</li>
|
||||
<li>Fixed dragging and dropping files from the home folder into the Linux Flatpak version.</li>
|
||||
<li>Fixed being able to switch document analysis policies while an analysis or media transcription was still in progress.</li>
|
||||
<li>Fixed file extension handling so files are recognized correctly regardless of uppercase or lowercase letters in their extensions. Thanks, Paul Schweiß, for reporting this issue.</li>
|
||||
<li>Fixed AI Studio failing to start on Linux systems & showing an outdated version on the Flatpak page.</li>
|
||||
<li>Upgraded Rust to v1.97.1.</li>
|
||||
<li>Upgraded .NET to v9.0.18.</li>
|
||||
<li>Upgraded Tauri to v2.11.5.</li>
|
||||
<li>Upgraded common dependencies.</li>
|
||||
<li>Upgraded runtime dependencies.</li>
