+# 2.29.0
+
+**Features:**
+
+* added utility `isCompilerOptionEnabled`
+
+# 2.28.0
+
+Typeguards are now split into multiple submodules for each version of TypeScript (starting with 2.8.0).
+That means you can now import directly from `"tsutils/typeguard/2.8"` to get compatible declaraton files for TypeScript@2.8.
+For more information please read the relevant section in [README.md](README.md).
+
+**Features:**

+
+**Bugfixes:**
+
+* `getControlFlowEnd` and `endsControlFlow`: correctly handle nested LabeledStatements
+* `endsControlFlow` removed erroneous special case when an IterationStatement is passed as argument whose parent is a LabeledStatement.
