Most of the functionality was untouched, there were only few deviations to the original styling and alignment of components. The most notable changes are as follows: - The backend and cache tables no longer have a range column, range requests are now indicated by a preceding ®. - The watcher graphs are rendered with a different library and no longer have a confusing x axis - The colors do not match the original version - The cluster stats page includes the role count - Errors retrieving metrics no longer exits the process. The footer is updated to display errors and requires manual intervention to exit. If errors are intermittent future successful reports will restore functionality.
