 - Added organization-wide management for the notice on AI-generated content. IT departments can switch it on for everybody, either fixed or as a default which users may change.
 - Added a choice of how AI Studio encrypts API keys, tokens, and passwords when you export providers, data sources, or tool settings for your organization. The new protected format needs AI Studio v26.10.1 or newer on every computer that reads it, and your encryption secret stays the same. If you used AI Studio before, your exports keep the previous format until you switch, so your organization can update all computers first. You find the choice in the app settings, under Enterprise Administration.
 - Added organization-wide management for the format in which exports encrypt API keys, tokens, and passwords. IT departments can set it for all their administrators, either fixed or as a default which users may change.
+- Added a way for IT departments to ask you for your personal API key on the start page. When the configuration of your organization brings providers that need your own key, the start page explains how to get it, checks the key with the provider, and stores it for all of these providers at once. Thanks, Dominic Neuburg (`donework`), 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.

 - Fixed AI Studio overlooking suspicious instructions (prompt injection) in files such as text or Markdown files when the instructions continued on the next line.
 - Fixed AI Studio removing harmless lines from files such as text or Markdown files, mistaking them for suspicious instructions (prompt injection).
 - Fixed AI Studio not checking the transcripts of audio and video files for suspicious instructions (prompt injection) in the Batch Processing assistant and when you load such a file into a field of an assistant. AI Studio now checks these transcripts like all other documents before the AI sees them, even very long ones.
+- Fixed AI Studio deleting the API keys you entered yourself for the providers of your organization when your organization changed the secret that protects its configuration. These keys now stay, so you no longer need to enter them again.
 - Updated the code contributions on the supporters page, which now thank everyone who has contributed code to AI Studio so far.
 - Upgraded several libraries to improve security.
 - Upgraded to Rust v1.99.0
