 Released 2018-mm-dd
 
 New features:
 - CI tests with Ubuntu Xenial + PostgreSQL 10.1 and Ubuntu Precise + PostgreSQL 9.5

+- Upgrades Windshaft to [4.8.0](https://github.com/CartoDB/Windshaft/blob/4.8.0/NEWS.md#version-480) which includes:
+  - Update internal deps.
   - A fix in mapnik-vector-tile to avoid grouping together properties with the same value but a different type.
   - Performance improvements in the marker symbolizer (local cache, avoid building the collision matrix when possible).
   - MVT: Disable simplify_distance to avoid multiple simplifications.
   - Fix a bug with zero length lines not being rendered when using the marker symbolizer.
 - Upgrades Camshaft to [0.61.9](https://github.com/CartoDB/camshaft/releases/tag/0.61.9):
   - Use Dollar-Quoted String Constants to avoid Syntax Error while running moran analyses.
+- Update other deps:
+  - body-parser: 1.18.3
+  - dot: 1.1.2
+  - express: 4.16.3
+  - lru-cache: 4.1.3
+  - node-statsd: 0.1.1,
+  - queue-async: 1.1.0
+  - request: 2.87.0
