Release 0.14.0

Highlights:

This release comes with two main new features.

Probe plugins: Now you can create your HTTP-based plugin to provide new metrics and display them in Scope. You can read more about it and see some examples here.
Metrics on canvas: Metrics are now displayed on the nodes and not just on the details panel, starting with CPU and memory consumption.

Also, the performance of the UI has been considerably improved and the 100-node rendering limit has been lifted.
