 nhdplusTools 0.3.15
 ==========
 * Added `discover_nldi_characteristics()` and `get_nldi_characteristics()`
+* Changed `navigate_nldi()` to use the new NLDI navigation end point. Distance is now required.
 * Fixed a bug in `get_flowline_index()` to handle multipart lines.
 * Added flowline_only input to `plot_nhdplus()` to improve scalability
 * Added streamorder filtering to `subset_nhdplus()` for download filtering.
