About Citrix Receiver for HTML5 2.3

Jan 13, 2017

Citrix Receiver for HTML5 is hosted on StoreFront servers and enables users to access virtual desktops and hosted applications from a web browser. Resources delivered by XenDesktop and XenApp are aggregated in a StoreFront store and made available through a Citrix Receiver for Web site. With Citrix Receiver for HTML5 enabled on the site, users can access desktops and applications within their web browsers without needing to install Citrix Receiver locally on their devices.

When used in conjunction with the centralized customization and branding capabilities of the StoreFront 3.0 (and later), users of this Citrix Receiver for HTML5 release will receive a centrally managed app and desktop selection experience from StoreFront. This is the same consistent user experience that can be received by the Windows and Mac desktop Citrix Receivers and Chrome web Citrix Receiver when associated with the StoreFront.

What's new in this release

Support for selective use of H.264 in Thinwire

Citrix Receiver for Chrome now supports selective use of H.264 in Thinwire, plus encoding of transient content instead of the JPEG encoder available on the VDA. This feature is available only on VDAs Version 7.11 or later.

For more information on configuring Selective H.264, see Configuring Selective H.264.

Enhancement to caching behavior of video content in Thinwire

Thinwire can now bypass caching of server-rendered video content while at the same time retaining cached bitmaps for other open windows using text-based data (for example Excel, Windows Explorer, desktop background), resulting in a 5% reduction in bandwidth use. This enhancement is available in XenApp and XenDesktop 7.11 or later.

For more information on configuring Thinwire, see the XenApp and XenDesktop documentation.
