Good day all.
With the release of Rancher 2.9, some important changes happened with the Rancher UI, which may impact your extension.
In the case that your built extension doesn’t work with Rancher 2.9, we have created this guide
https://extensions.rancher.io/extensions/rancher-2.9-support in order to help you with this transition of making it Rancher 2.9 compliant.
We are also in the process migrating the Rancher UI to Vue 3, which will published with the release of Rancher 2.10.0. We will be keeping you posted
https://extensions.rancher.io/extensions/rancher-2.10-support
We are working towards making extensions even better!
Thank you for your understanding and we hope to continue to see new and exciting extensions for Rancher.
