Points to Note

Some important aspects to keep in mind while using Build 50.28.

Changes in Citrix product names

  • We are unifying our product portfolio. If you have been a Citrix customer or partner for a while, you will notice new names in our products and in the product documentation. The new product and component names stem from the expanding Citrix portfolio and Cloud strategy. For more information about the Citrix unified portfolio, see https://www.citrix.com/about/citrix-product-guide/.
    We are also making it easier to understand the value of our solutions with new names. The product documentation might still contain former names. For example, you might see instances of earlier names in console text, messages, and directory/file names. Some items, such as commands, might continue to retain their former names to prevent breaking existing customer scripts. Related product documentation and other resources (such as videos and blog posts) linked from this product's documentation might still contain former names. We appreciate your patience during this transition.

AppFlow

  • If you have more than one AppFlow collectors associated to an AppFlow action with distribution algorithm enabled, the video detection AppFlow records are sent only to one collector. In addition, if one collector goes down, the video AppFlow records are not sent to other collectors. As a result, the records are lost.
