(Action Required) Compute Services, Pending Rust Version 1.84 Release in January 2025

Customer MessagingOn the 9th of January 2025, Rust will be releasing a new version of its coding language, version 1.84. Our Engineers will be performing additional research into this new version to ensure optimal compatibility with our Compute platform. Customers identified to have services impacted by this change, would have received an email notification with additional details. Refer to subject line, (Action Required) Compute Services, Pending Rust Version 1.84 Release in January 2025In order to avoid issues or disruption when attempting to build existing Compute projects, we ask that our customers with Rust-based Compute services not perform an update to Rust version 1.84 or later until you have received a software development kit (SDK) update from Fastly.What’s Changing?A new version of Rust is scheduled to be released on the 9th of January 2025 that has not been fully vetted by our Engineers to ensure that the version is supported on our Compute platform.What’s next? What do I have to do?In accordance with our standardized best practice, customers who have Rust-based Compute services should update their Fastly CLI to the latest version (v10.17.0), or later,  in order to run adequate checks on your version of Rust and compatibility with Compute, before building and deploying your code to the platform.Our engineers are currently evaluating the upcoming Rust release (v1.84), and will release a subsequent SDK update once 1.8.4 platform compatibility is confirmed.Additionally, if you are using the Rust toolchain in your CI pipeline, then you will also need to apply an upper bound for Rust at v1.83 as well.Customers with any questions or concerns may engage with our Support team through https://support.fastly.com or by contacting your designated account management team members.
