With new breakthroughs, innovations and exciting digital experiences emerging, last year was pivotal for the content delivery space. And now that we’re fully immersed in 2023, the pace of disruption will only get faster across the entire digital ecosystem.

Today is March 15th and that means it’s release day! Every year on March 15th and September 15th, a new version of Varnish Cache is released.

Varnish Cache is the open source version of Varnish and version 7.3 of the project becomes available today.

Recently, Varnish Technical Evangelist Thijs Feryn led a webinar covering Varnish Configuration Language (VCL), the unique programming language that powers all of our software, as well as the popular open source Varnish Cache. For those who weren’t able to attend the webinar, you can watch it here.  

Varnish Controller is our orchestration tool, built to manage Varnish Enterprise architectures of any size. Packed with provisioning, monitoring, and scaling capabilities, Varnish Controller operates on both Varnish clusters and multi-tenant environments. We’re continuing to improve this tool’s performance, flexibility, and ease of use with the latest update, Controller 5.1. Along with a comprehensive series of bug fixes and UI improvement, this update includes several brand new additions to Controller, including a host of new customization options for Traffic Router, the addition of debug headers for RoutingRules, and better graphs on the Controller dashboard.
