This new version looks good ! This is far way better than the black dark previous one, 5.0 until 5.3. The first I must do every time I'm deploying a Web Interface is to change the template to something a bit brighter... This version 5.4 bring a "corporate" design and some new functionality : Updated end user interface. The layout and color scheme for end users has been updated to help improve navigation and readability. Session sharing for VM hosted applications. The Web Interface now supports session sharing for Virtual Machine (VM) hosted apps. This feature is only available for seamless applications and non-anonymous users. Multiple desktop access for users. In previous versions of the Web Interface, users could only access a single instance of a desktop per desktop group. Now, users can access multiple instances of desktops in desktop groups. For more information about assigning desktops to users, see the XenDesktop version 5 documentation. Improved smart card support for Access Gateway. Smart card authentication to the Web Interface is now compatible with more environments. The Web Interface can now accept User Principal Names (UPNs) from Access Gateway as well as the user name and domain. Additionally, the Web Interface has been updated to comply with FIPS. This new functionality can only be used with the pass-through authentication for smart card option and you must be logged on as a domain administrator. For more information about configuring smart card support for Access Gateway, see the Access Gateway documentation. Ability to set additional default values. Administrators can configure default values for all bandwidth-related settings, such as audio quality, color depth, bandwidth profile, printer mapping, and window size. ICA File Signing. The Web Interface digitally signs generated ICA files, to allow compatible ICA clients to validate that the file originates from a trusted source. This is what is announce by Citrix here : Web Interface what's new on eDocs Before I begin to dig deeper, here are some screen shots : and for the mobile side, the light edition of the Web Interface, it have been revisited as well : Now, is it really only what's new ? nothing under the hood ? I'm still trying to find out something new while I'm waiting for XenDesktop 5 :) Regarding debugging, the blog I wrote a while ago now is still functional : Web Interface 4.x 5.x Debug Mode Sources : Citrix eDocs…
