+## 1.15.0
+
+* New strategies for making tiles smaller, with uniform behavior across
+  the whole zoom level: --increase-gamma-as-needed,
+  --drop-densest-as-needed, --drop-fraction-as-needed,
+  --drop-smallest-as-needed.
+* Option to specify the maximum tile size in bytes
+* Option to turn off tiny polygon reduction
+* Better error checking in JSON parsing
+
 ## 1.14.4
 
 * Make -B/-r feature-dropping consistent between tiles and zoom levels

  * -ag or --calculate-feature-density: Add a new attribute, `tippecanoe_feature_density`, to each feature, to record how densely features are spaced in that area of the tile. You can use this attribute in the style to produce a glowing effect where points are densely packed. It can range from 0 in the sparsest areas to 255 in the densest.
  * -ab or --detect-shared-borders: In the manner of [TopoJSON](https://github.com/mbostock/topojson/wiki/Introduction), detect borders that are shared between multiple polygons and simplify them identically in each polygon. This takes more time and memory than considering each polygon individually.
  * -aG or --increase-gamma-as-needed: If a tile is too large, try to reduce it to under 500K by increasing the `-g` gamma. The discovered gamma applies to the entire zoom level.
- * -am or --merge-polygons-as-needed: If a tile is too large, try to reduce it to under 500K by merging adjacent polygons together
  * -as or --drop-densest-as-needed: If a tile is too large, try to reduce it to under 500K by increasing the minimum spacing between features. The discovered spacing applies to the entire zoom level.
  * -ad or --drop-fraction-as-needed: Dynamically drop some fraction of features from each zoom level to keep large tiles under the 500K size limit. (This is like `-pd` but applies to the entire zoom level, not to each tile.)
  * -an or --drop-smallest-as-needed: Dynamically drop the smallest features (physically smallest: the shortest lines or the smallest polygons) from each zoom level to keep large tiles under the 500K size limit. This option will not work for point features.
