Version 0.3.0

This is the third beta release of the KEDA HTTP Addon. Please see the install documentation to get started.

The largest change in this release is that operators now have the option of running a single cluster-global installation. This means that an HTTP Addon installation (e.g. scaler, interceptor, and operator) can now be scoped either to one namespace, or the entire cluster. The latter case is called a cluster-global install. If you do want to run a cluster-global HTTP Addon, you must:

1. Not run any other KEDA HTTP Addon installations, even if they are scoped to one namespace
2. Also run a cluster-global installation of KEDA itself

Breaking changes

There are no backward-incompatible changes to HTTPScaledObjects. However, there is a breaking change to the internal URL routing table. To overcome this, please delete your HTTP Addon installation (using helm delete if you're using the Helm chart) and re-install it at the 0.3.0 version.

Other significant changes

While the cluster-global feature is the biggest in this release, we have made several internal improvements such as:

• Using the Kubernetes client library's informer framework in #326 (thanks to @tpiperatgod)
• The ability to restore the target Deployment to its original replica count after deleting the associated HTTPScaledObject in #339 (thanks to @tpiperatgod)
• Compiling operator, interceptor and scaler with the SHA of the source code they were built with, and adding an HTTP endpoint to each process's admin server to output this information in #377 (thanks to @asw101)
• Returning a custom header for all requests that triggered a "cold start" (i.e. scaling up from 0 replicas) in #366 (thanks to @asw101)
