## Issue management

We use GitHub to track all of our bugs and feature requests. Each issue we track has a variety of metadata:

- **Epic**. An epic represents a feature area for Istio as a whole. Epics are fairly broad in scope and are basically product-level things.
Each issue is ultimately part of an epic.

- **Milestone**. Each issue is assigned a milestone. This is 0.1, 0.2, ..., or 'Nebulous Future'. The milestone indicates when we

Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce,

b) Subject to the terms of this Agreement, each Contributor hereby grants

This behavior is consistent across all keys; each key self-documents itself with valid examples.

The following sub-systems are dynamic i.e., configuration parameters for each sub-systems can be changed while the server is running without any restarts.
