+Hi, figured we could actually use a changelog now:
+
+## 1.1.4 2017-04-21
+
+* Fix typo in package.json
+
+## 1.1.3 2017-04-21
+
+* Improve documentation and limit files included in the distribution.
+
+## 1.1.2 2016-03-15
+
+* Add tracker group cycle detection and tests for it
+
+## 1.1.1 2016-01-29
+
+* Fix a typo in stream completion tracker
+
+## 1.1.0 2016-01-29
+
+* Rewrote completion percent computation to be low impact– no more walking a
+  tree of completion groups every time we need this info.  Previously, with
+  medium sized tree of completion groups, even a relatively modest number of
+  calls to the top level `completed()` method would result in absurd numbers
+  of calls overall as it walked down the tree. We now, instead, keep track as
+  we bubble up changes, so the computation is limited to when data changes and
+  to the depth of that one branch, instead of _every_ node. (Plus, we were already
+  incurring _this_ cost, since we already bubbled out changes.)
+* Moved different tracker types out to their own files.
+* Made tests test for TOO MANY events too.
+* Standarized the source code formatting
