+## [2.0.0] - 2017-07-30
+
+### Changed
+
+- Specified version numbers for all dependencies, due to Chalk dropping support for older Node versions
+
+  This may be a **breaking change** if you depend on a newer release of any dependency, so you can continue using 1.2.2 in that case. 
+
+## [1.2.2] - 2016-06-29
+
+### Changed
+
+- Now passes the error back to GulpUtil.PluginError
+
+## [Older]
