+## 0.12.3 - 2018-10-19
+
+ * Fixed dart-lang/coverage#194. During collection, we now track each script by
+ its (unique) VMScriptRef. This ensures we look up the correct script when
+ computing the affected line for each hit token. The hitmap remains URI
+ based, since in the end, we want a single, unified set of line to hitCount
+ mappings per script.
+
## 0.12.2 - 2018-07-25
* Dart SDK upper bound raised to <3.0.0.
