+## [1.6.0] - 2020-05-22
 
 ### Added
 - Specify `source_columns: true` for shapefiles to import all attributes
 - Support creating tiles from shapefiles only (i.e. no .osm.pbf)
 - `attribute_function` to rewrite shapefile attributes from Lua
 - Improved diagnostics for invalid multipolygons
 - Output shapefile layer names when reading
+- Report memory usage in verbose mode
 
 ### Changed
 - Rewrite OpenMapTiles-compatible processing (@systemed, @sasfeat, @typebrook, @leonardehrenfried)
 - `--combine` flag now off by default
 - 32-bit ways and 16-bit tile index by default, change with `-DFAT_WAYS -DFAT_TILE_INDEX`
 - Use tsl::sparse_map instead of std::unordered_map for ~7% memory saving
+- Don't write invalid small polygons
 - Speedup for shapefile reading (@TimSC)
 - Move to Github Actions instead of Travis (@leonardehrenfried)
 - Reduce size of Docker image, use Ubuntu 20.04 (@leonardehrenfried)
-- Improve area calculation (@typebrook)
+- Improve area and length calculation (@typebrook, @systemed)
+- Overwrite existing .mbtiles file by default
 
 ### Fixed
 - CMake build fixed (@ogre)

@@ -124,6 +124,7 @@ To do that, you use these methods:
 * `node:Find(key)` or `way:Find(key)`: get the value for a tag, or the empty string if not present. For example, `way:Find("railway")` might return "rail" for a railway, "siding" for a siding, or "" if it isn't a railway at all.
 * `node:Holds(key)` or `way:Holds(key)`: returns true if that key exists, false otherwise.
 * `node:Id()` or `way:Id()`: get the OSM ID of the current object.
+* `way:Length()` and `way:Area()`: return the length (metres)/area (square metres) of the current object. Requires recent Boost.
 * `node:Layer("layer_name", false)` or `way:Layer("layer_name", is_area)`: write this node/way to the named layer. This is how you put objects in your vector tile. is_area (true/false) specifies whether a way should be treated as an area, or just as a linestring.
 * `way:LayerAsCentroid("layer_name")`: write a single centroid point for this way to the named layer (useful for labels and POIs).
 * `node:Attribute(key,value)` or `node:Attribute(key,value)`: add an attribute to the most recently written layer.
