 ## Changes to QL libraries
 
 * The class `ControlFlowNode` (and by extension `BasicBlock`) is no longer
-  directly equatable to `Expr` and `Stmt`. Any queries that exploit these 
-  equalities, for example by using casts, will now report compilation errors. 
-  You can fix these errors by making minor changes to the affected classes.
-  The conversion can be inserted in either direction depending on what is most 
-  convenient. Available conversions include `Expr.getControlFlowNode()`, 
-  `Stmt.getControlFlowNode()`, `ControlFlowNode.asExpr()`, 
-  `ControlFlowNode.asStmt()`, and `ControlFlowNode.asCall()`. 
-  Exit nodes were until now modeled as a `ControlFlowNode` equal to its 
+  directly equatable to `Expr` and `Stmt`. Any queries that exploit these
+  equalities, for example by using casts, will now report compilation errors.
