Dear Customer,

As communicated in October 2024, and in our status post on the 7th of November 2024, Fastly will be making changes to our device detection library.

Customers will be upgraded to the new library in phases through the 8th of January 2025, after which support for the current library will cease. The new library began rolling out the first week November 2024.

Why am I receiving this message?

These changes will impact some of the client variables used in your custom VCL code. As part of this process we are also deprecating a small portion of variables.

What do I have to do?

1. Identify where you use the following client.* variables in your service's custom VCL. These will be deprecated.

The variables listed below will no longer return data resulting in empty values when accessing the device detection library.

client.class.checker
client.class.filter
client.class.masquerading
client.class.spam
client.platform.manufacturer
client.display.height
client.display.width
client.display.ppi
client.class.downloader
client.class.feedreader
client.platform.ereader
client.platform.tvplayer
2) If you are using any of the deprecated variables, please remove them, or use Client Hints to fetch that information by no later than the 8th of January 2025.

If you require Fastly to coordinate with you while performing the upgrade, please contact Fastly customer support to schedule a time to switch to the new library.

The remaining client.* variables will continue to work with the caveat that some of the results returned may show values differently than before. Please reference our documentation on Migrating to Fastly’s universal device detection library for a list of updated VCL variables.

Please reference the original email and Fastly’s status page for more information.
