 * GR-61493 Added `RootNode.prepareForCall` which allows root nodes to prepare themselves for use as a call target (or to validate whether they can be used as a call target).
 * GR-57063 Bytecode-DSL: Improved variadic support. Variadic operands compile and execute now more efficiently with fewer reallocations.
 * GR-57063 Bytecode-DSL: Added an `startOffset` parameter to `@Variadic` which allows to reserve a fixed number of slots in the object array for custom use.
-* GR-57063 Bytecode-DSL: The `@Variadic` annotation can now also be used on `@Operation` annotated classes to indicate a dynamic variadic return values. Dynamic variadic return values are efficiently flattened into the object array of a variadic operand.
+* GR-57063 Bytecode-DSL: The `@Variadic` annotation can now also be used on `@Operation` annotated classes to indicate that the operation produces a dynamic variadic return value. Dynamic variadic return values are efficiently flattened into the object array of a variadic operand.
 * GR-57063 Bytecode-DSL: Added a `variadicStackLimit` parameter to `@GenerateBytecode` that allows to specify how many variable arguments are stored on the stack before they are collapsed into an object array.
