This update delivered improved performance, reliability, and quality compared to the legacy WebRTC-based optimization. It also unlocks   new features such as Gallery view (3&#215;3 and 7&#215;7), QoS, HID support, custom backgrounds, hardware acceleration, and 1080p video. Microsoft recommends enabling this optimization ahead of the upcoming WebRTC deprecation announcement.<\/p>\n<p><b>[When this will happen:]<\/b><\/p>\n<p>This update is available now. Microsoft recommends configuring your environment as soon as possible to ensure continued access to new Teams features.<\/p>\n<p><b>Who is affected:&nbsp;<\/b>Admins managing Citrix DaaS\/CVAD environments where Microsoft Teams is deployed<\/p>\n<p><b>What will happen:<\/b><\/p>\n<ul>\n<li>You are receiving this message because we detected that your Citrix DaaS\/CVAD environment is not configured to allow the custom virtual channels needed by Microsoft Teams so it can optimize users with the SlimCore architecture.<\/li>\n<li>If the virtual channels are not whitelisted, Microsoft Teams will only be able to optimize using the legacy WebRTC-based offloading.<\/li>\n<li>Since the new SlimCore-based optimization is where all new features will be introduced, Microsoft strongly recommends IT administrators reconfigure Citrix Studio policies.<\/li>\n<li>SlimCore-based optimization will not be available until the Citrix Studio policy that allows virtual channels is updated.<\/li>\n<li>Users will miss out on new Teams features and performance improvements.<\/li>\n<li>Microsoft will deprecate WebRTC optimization in a future update.<\/li>\n<\/ul>\n<p><b>[What you can do to prepare:]<\/b><\/p>\n<p>To enable SlimCore-based optimization:<\/p>\n<ul>\n<li>Review and update the <a href=\"https:\/\/learn.microsoft.com\/microsoftteams\/vdi-2#citrix-virtual-channel-allow-list\" target=\"_blank\">  Virtual channel allow list policy in Citrix<\/a>&nbsp;studio.<\/li>\n<li>Whitelist the following virtual channels: MSTEAMS, MSTEAM1, and MSTEAM2.<\/li>\n<li><a href=\"https:\/\/learn.microsoft.com\/microsoftteams\/vdi-2#step-2-plugin-installation-on-the-endpoint\" target=\"_blank\">Deploy the Citrix Plugin alongside the Citrix Workspace app<\/a>.
