I am pleased to announce that Spring Batch 6.0.0-RC2 is now available from Maven Central!

What's new in Spring Batch 6.0.0-RC2?

This second release candidate introduces a long-awaited feature which is the use of contextual lambda expressions to configure batch artefacts. This new style of configuration provides a more concise and readable way to define item readers and writers.

For example, instead of using the traditional builder pattern like in the following snippet to define a delimited file reader:

var reader = new FlatFileItemReaderBuilder()
    .resource(...)
    .delimited()
    .delimiter(",")
    .quoteCharacter('"')
    ...
    .build();

You can now use a lambda expression to configure the delimited options like this:

var reader = new FlatFileItemReaderBuilder()
    .resource(...)
    .delimited(config -> config.delimiter(',').quoteCharcter( '"' ))
    ...
    .build();

This release also comes with several bug fixes, performance improvements and dependency upgrades.

For the complete list of changes, please check the release notes.
