 # v26.6.1, build 241 (2026-06-xx xx:xx UTC)
 - Added support for up to 100 thousand enterprise configuration slots, using fixed-width slot names such as `config_00000` while keeping the existing first ten slot names compatible.
 - Added support for managed custom root certificate bundles and host allowlists for external HTTPS requests, helping Flatpak deployments connect to organization-internal services with private root CAs while keeping built-in cloud provider endpoints on system trust.
+- Added support for reading enterprise policy files from a Flatpak provisioning extension.
 - Added startup path and Linux package type details to the information page to make support easier.
 - Improved the enterprise configuration details on the information page by showing where each configuration comes from and which configuration slot was used.

 The directories from `$XDG_CONFIG_DIRS` are processed in order.
 
+#### Flatpak policy directory
+
+When AI Studio runs as a Flatpak, it first checks this sandbox path before the regular Linux policy directories:
+
+`/app/etc/MindWorkAI/`
+
+This path is intended for a Flatpak provisioning extension like:
+
+```yaml
+add-extensions:
+  org.MindWorkAI.AIStudio.provisioning:
+    directory: etc/MindWorkAI
+    no-autodownload: true
+```
+
+Policy files can then be provided on the host through the extension directories. For example:
+
+- System-wide, read-only: `/var/lib/flatpak/extension/org.MindWorkAI.AIStudio.provisioning/x86_64/stable/`
+- User-specific: `$XDG_DATA_HOME/flatpak/extension/org.MindWorkAI.AIStudio.provisioning/x86_64/stable/`
+
+Files placed there are mounted into the sandbox at `/app/etc/MindWorkAI/`. Use the same policy file names and YAML format described below.
+
 #### macOS policy directory
 
 `/Library/Application Support/MindWork/AI Studio/`
