-* PROMOTION: `@Wither` has been promoted to the main package, renamed to `@With`. Otherwise, no changes have been made to the annotation.

 * FEATURE: You can now configure a custom logger framework using the new `@CustomLog` annotation in combination with the `lombok.log.custom.declaration` configuration key. See the [log documentation](https://projectlombok.org/features/Log) for more information. [Pullrequest #2086](https://github.com/rzwitserloot/lombok/pull/2086) with thanks to Adam Juraszek.
 * 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) and [Pull Request #2138](https://github.com/rzwitserloot/lombok/pull/2138) with thanks to Alexander Bulgakov.
