+### `0.44.0` — November 8, 2018
+
+###### NEW
+
+**Introducing the `child_min_invalid` and `child_max_invalid` schema errors.** These new schema errors map directly to the `mix` and `max` schema rule definitions, and make it easier to determine exactly what your normalization logic needs to do to fix the document.
+
+**Added new node retrieval methods.** There are three new methdos for node retrieval. The first is `getNodesAtRange` which will retrieve _all_ of the nodes in the tree in a given range. And the second two are `getRootBlocksAtRange` and `getRootInlinesAtRange` for retrieving the top-most blocks or inlines in a given range. These should be helpful in defining your own command logic.
+
+###### BREAKING
+
+**Schema errors for `min` and `max` rules have changed.** Previously they would result in errors of `child_required`, `child_object_invalid`, `child_type_invalid` and `child_unknown`. Now that we have the new `child_min_invalid` and `child_max_invalid` errors, these schema rules will return them instead, making it much easier to determine exactly which rule is causing a schema error.
+
+###### DEPRECATED
+
+**The `getBlocksAtRange` and `getInlinesAtRange` methods have been renamed.** To clear up confusion about which blocks and inlines are retrieve in the case of nesting, these two methods have been renamed to `getLeafBlocksAtRange` and `getLeafInlinesAtRange` to clarify that they retrieve the bottom-most nodes. And now there are two additional methods called `getRootBlocksAtRange` and `getRootInlinesAtRange` for cases where you want the top-most nodes instead.
