 ### v1.18.9 "Edgy Guinea Pig"
 * ENHANCEMENT: Thanks to Mark Haynes, the `staticConstructor` will now also be generated if a (private) constructor already exists. [Issue #2100](https://github.com/rzwitserloot/lombok/issues/2100)
 * ENHANCEMENT: `val` is now capable of decoding the type of convoluted expressions (particularly if the right hand side involves lambdas and conditional (ternary) expressions). [Pull Request #2109](https://github.com/rzwitserloot/lombok/pull/2109) with thanks to Alexander Bulgakov.
+* BUGFIX: Delombok would turn something like `List<byte[]>...` in a method parameter to `List<byte...>...` [Issue #2140](https://github.com/rzwitserloot/lombok/issues/2140)
 
 ### v1.18.8 (May 7th, 2019)
