This release introduces the support of SAP HANA as an additional supported database for the job repository.
==== New Maven Bill Of Materials for Spring Batch modules
This feature has been requested several times and is finally shipped in v5. It is now possible to use the newly
added Maven BOM to import Spring Batch modules with a consistent version number.
==== UTF-8 by default
Several issues related to characters encoding have been reported over the years in different
areas of the framework, like inconsitent default encoding between file-based item readers
and writers, serialization/deserialization issues when dealing with multi-byte characters
in the execution context, etc.
In the same spirit as link:$$https://openjdk.java.net/jeps/400$$[JEP 400] and following the
link:$$http://utf8everywhere.org$$[UTF-8 manifesto], this release updates the default encoding
to UTF-8 in all areas of the framework and ensures this default is configurable as needed.
==== Native support
The effort towards providing support to compile Spring Batch applications as native executables
using the GraalVM native-image compiler has started in v4.2 and was shipped as experimental in v4.3.
In this release, the native support has been improved significantly and is now considered out of beta.
=== Pruning
Spring Batch 5 removes a number of items that are no longer needed, including:
* <<deprecated-apis-removal>>
* <<api-deprecation-and-removal>>
* <<sqlfire-support-removal>>
* <<jsr-352-implementation-removal>>
