 # Changelog
 
+## 5.4.0
+Released 2018-03-15
+ - Upgrades Windshaft to 4.5.7 ([Mapnik top metrics](https://github.com/CartoDB/Windshaft/pull/597), [AttributesBackend allows multiple features if all the attributes are the same](https://github.com/CartoDB/Windshaft/pull/602))
+ - Implemented middleware to authorize users via new Api Key system
+ - Keep the old authorization system as fallback
+ - Aggregation widget: Remove NULL categories in 'count' aggregations too
+ - Update request to 2.85.0
+ - Update camshaft to 0.61.4 (Fixes for AOI and Merge analyses)
+ - Update windshaft to 4.6.0, which in turn updates @carto/mapnik to 3.6.2-carto.4 and related dependencies. It brings in a cache for rasterized symbols. See https://github.com/CartoDB/node-mapnik/blob/v3.6.2-carto/CHANGELOG.carto.md#362-carto4
+ - PostGIS: Variables in postgis SQL queries must now additionally be wrapped in `!` (refs [#29](https://github.com/CartoDB/mapnik/issues/29), [mapnik/#3618](https://github.com/mapnik/mapnik/pull/3618)):
