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.
Added organization-configurable defaults and visibility controls for the Visual Briefing Assistant.
Added a share button for plugins, which uses the native share dialog on Windows and macOS. For Linux, we added an export option for plugins, which stores the plugin archive at a location of your choice.
Added an import button on the plugin page to install plugin archives directly from your files.
Added the option to import plugins by dropping a plugin archive onto the plugin page.
Added the dedicated file extension .mwplugin for plugin archives.
Added an option for organizations to disable importing, sharing, and exporting plugins.
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. Afterwards, 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.
Upgraded dependencies to their latest versions to improve security and stability.
