+# 3.0.1
+
+This is a big change in Turf! 3.0.0 is a release that targets the development
+cycle of Turf, letting us work on it more and release more often.
+
+**Monorepo**
+
+Turf 3.x and forward is a **monorepo** project. We publish lots of little modules
+as usual, but there's one repo - turfjs/turf - that contains all the code
+and the issues for the Turf source code. We use [lerna](https://lernajs.io/)
+to link these packages together and make sure they work.
+
+Why? We already had internal turf modules, like `turf-meta`, and development
+was harder and harder - we had a bunch of custom scripts to do releases and
+tests, and these were just written for Turf. Lerna is from the very popular
+and very well-maintained [babel](http://www.babeljs.io) project, and it
+works really well, and reduces maintainer sadness.
+
+**Simplicity**
+
+Turf grew a bunch of modules that weren't totally necessary, or were
+expressing only a line or two of JavaScript. We want to make things easier,
+but these modules didn't make code more expressive and they hid complexity
+where it didn't need to be hidden. Turf 3.x focuses on the core
+functionalities we need, making sure they're tested and performant.
+
+turf-erase has been renamed turf-difference to make its name more similar to the equivalents in other libraries.
+
+Removed modules: merge, sum, min, max, average, median, variance, deviation, filter, remove, jenks, quantile.
+See the upgrade guide below for replacements.
+
+**Upgrading from v2**
+
+**If you were using turf-merge**
+
+turf-merge repeatedly called turf-union on an array of polygons. Here's
+how to implement the same thing without the special module
+
+```js
+var clone = require('clone');
+var union = require('turf-union');
+function merge(polygons) {
+  var merged = clone(polygons.features[0]), features = polygons.features;
+  for (var i = 0, len = features.length; i < len; i++) {
+    var poly = features[i];
+    if (poly.geometry) merged = union(merged, poly);
+  }
+  return merged;
+}
+```
+
+**If you were using turf-sum, min, max, average, median, variance, deviation**
+
+The `turf-collect` method provides the core of these statistical methods
+and lets you bring your own statistical library, like `simple-statistics`,
+`science.js`, or others.
+
+**If you were using turf-filter, turf-remove**
+
+These modules were thin wrappers around native JavaScript methods: use
+[Array.filter](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter) instead:
+
+```js
+var filteredFeatures = features.filter(function(feature) {
+  return feature.properties.value > 10;
+});
+```
+
+**If you were using turf-jenks, turf-quantile**
+
+Use Array.map to get values, and then bring your own statistical calculation,
+like simple-statistics or science.js.
+
+```js
+var values = features.map(function(feature) {
+  return feature.properties.value;
+});
+```
+
