 - Added an option for organizations to disable importing, sharing, and exporting plugins.
 - Added the option to import configuration plugins from a file. Before installing, AI Studio shows what the configuration 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 separate option for organizations to disable importing configuration plugins. Organizations can now let people import assistants while keeping configurations to their IT department.
-- Added a delete button for configuration plugins you placed yourself. Until now, such a plugin could only be removed from the data directory by hand, because configuration plugins have no on/off switch. Before deleting, AI Studio lists what disappears with it, such as providers, data sources, and settings that return to their default. Configurations deployed by your IT department cannot be deleted.
+- Added sharing and importing for language plugins. 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, and they can install it just as easily.
+- Added a delete button for configuration 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. Plugins shipped with AI Studio and plugins deployed by your IT department cannot be deleted.
 - 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.
 - 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.
 - 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.
