On the 26th of August 2025, we released an update to the VCL Editor in the Fastly Control Panel. This release unified Snippets, Custom VCL, and Complete VCL into a single, modernized view.

What has Changed

This update introduced several improvements:

  • Modernized Code Editor: Enjoy a smoother coding experience with syntax highlighting, error checking, and code folding.

  • Full-Screen Mode: Expand the editor to easily read, edit, and review complex VCL.

  • Unified VCL View: Manage VCL Snippets, Custom VCL, and Complete VCL in one place to simplify your workflow.

  • Editable Dynamic Snippets: Add and edit Dynamic Snippets directly in the UI.

  • Boilerplate Insertion: Insert boilerplate code directly from the Custom VCL view.

  • Auto-Generated Code: Reduce manual effort by automatically generating standard VCL functions and variables.

To learn more about these changes, please see our documentation: About VCL snippets and Using VCL snippets.
