## Features

- Renamed **-edge** tags to **-rolling**
- Added {doc}`Session Staging <../guide/staging>` to allow Administrators to pre-create session containers for faster user access.
- Added {doc}`Session Casting <../guide/casting>`. Administrators can expose custom URLs that will automatically launch Kasm sessions. The Casting URLs can optionally be used without authentication.

- Added the ability to clone an Image.
- Added  **Require GPU** and select **GPU Count** support in {doc}`Image Setting<../guide/custom_images>`.  The system will now report the GPUs discovered on the Agent.
- Added **Allow Network Selection** to {doc}`Image Setting<../guide/custom_images>`. When enabled, users will be able to select the Docker network the session is created on.
- Added **Categories** to {doc}`Image Setting<../guide/custom_images>` to allow Images to be grouped on the user dashboard.
- {doc}`Web Filter Policies <../guide/web_filtering>` can now be assigned to Images.  Image policies take priority over those assigned to Group Settings.
- Added **enable_ui_server_logging** {doc}`Group Setting <../guide/groups>`. If enabled, log messages will be sent from client browser to the Kasm Workspaces servers.
- Added **display_ui_errors** {doc}`Group Setting <../guide/groups>`. If enabled, detailed information will be displayed on the client browser in the event of an error.
- Added **allow_zone_selection** {doc}`Group Setting <../guide/groups>` to allow users to select the {doc}`Deployment Zone <../guide/zones/deployment_zones>` for new sessions.
- Added **session_time_limit** {doc}`Group Setting <../guide/groups>` and {doc}`Image Setting<../guide/custom_images>`. If configured, sessions will automatically expired after a set amount of time. A countdown timer will be displayed to the user.
- Added **dashboard_redirect** {doc}`Group Setting <../guide/groups>`. If configured, standard users will be redirected to the defined external website instead of being shown the main dashboard screen.
- Updated the {code}`get_user`{doc}`API <../developers/developer_api>` to support sending the username.
- Added **Keepliave** to the {doc}`Developer API <../developers/developer_api>` allowing developers extend the lifetime of a session.
- Added **Splash Background URL** and **Login Splash Background URL** to  {doc}`Custom Branding <../how_to/branding>`

- Removed X and via headers from Web Filter proxy.
- Fixed issue where the system would report a locally built image with multiple tags as unavailable.
- Fixed SAML logout error with IdPs that utilized {code}`nameIdEncrypted`.
- The **Available Slots** would be reported incorrectly on the **Zones** page.
