v2.0.0-beta2

🎉 Welcome to Defguard 2.0 Beta 2 🎉

This is the final beta before the stable release. Our primary focus has been on stabilising the platform and ensuring everything is ready for a smooth, production-grade launch.

📖 A comprehensive list of the changes implemented since Alpha 2 is documented in detail here: https://defguard.net/blog/defguard-2-0-release-beta-1/.

🛠️ We highly recommend previewing it yourself. We prepared a guide explaining how to run the alpha2 before. To run the beta2 just use 2.0.0-beta2 image tags instead of 2.0.0-alpha2.

⚠️ Important notice for beta1 early adopters: beta2 introduces a breaking change that requires removing and re-adding the Edge and Gateway components.

🛠️ We highly recommend that you get familiar with a detailed technical overview of all changes and a comprehensive showcase of all features in this blog post.

🚀Here you can find a quick tutorial on how to quickly launch 2.0α with Docker Compose.
