About Citrix Receiver for HTML5 2.1

Nov 01, 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.

New in this release

Enhanced HDX SDK

This release of Citrix Receiver for HTML5 provides an enhanced user experience by incorporating additional APIs to the HDX SDK paradigm. With these additional APIs, the SDK consumers can:

  • switch between fixed and dynamic resolution in an active session. With this functionality, users can change session resolution from fixed to auto fit and vice versa.
  • disable the session close alert on reload/close of the page when the session is launched. 
  • set a preferred language for the session. By default, the session uses the language set in the browser.
Refer to the download page for the latest HDX SDK.

Fixed issues

This release resolves the following issue:

  • After launching a session, a single tap would erroneously perform a tap and hold function which displayed a contextual menu. This issue occurred intermittently on hybrid platforms, and could also occur on other mobile devices. [#0621064]
