Version 2.7.0

Enhancements

• Caches generated marshallers across MessageMarshaller instances

Version 2.6.0

Enhancements

• Adds compatibility with protobuf v26+ (4.x.x on Maven)

BREAKING CHANGES

• Jackson 2.10+ (2021) required
• protobuf-java 3.18.0+ (2021) supported, earlier versions should continue to work but are not tested

Because it has been several years since these versions were released and it is common in the Java ecosystem to keep Jackson at the latest version to address CVEs, we have decided to not raise the major version along with these version floors.

Version 2.5.0

Note that due to an error running the release build, the same version was published both as 2.4.0 and 2.5.0. It is fine to skip 2.4.0 and we will not create a GitHub release for it.

Enhancements

• Add includingDefaultValueFields option with specific fields

Bugfixes

-Do not assume interning for non-ParserBase parsers to support treeAsTokens parser

Full Changelog: v2.3.0...v2.5.0

Version 2.3.0

Bugfixes

• Fix optional field not serialized when set to default value

Full Changelog: v2.2.0...v2.3.0

Version 2.2.0

Enhancements

• Adds MessageMarshallerModule to simplify registering MessageMarshaller with an ObjectMapper
  • This library only has an optional dependency on jackson-databind and expects the application to be including it to use
  • MessageMarshaller will consult the types in the ObjectMapper before marshalling nested messages. This can be used to customize marshalling of nested messages if needed

Full Changelog: v2.1.0...v2.2.0

Version 2.1.0

Enhancements

• Adds MessageMarshaller.toBuilder to allow adding a prototype to a marshaller without rebuilding all of them

Full Changelog: v2.0.0...v2.1.0

Version 2.0.0

Enhancements

• Adds support for newly introduced optional fields

BREAKING CHANGES

• Java 8+ required
• protobuf-java 3.12.0+ required

If you use an older version of either of these, continue to use the older version of protobuf-jackson. There are no other breaking changes, notably the API and ABI have not been changed. If you already use the appropriate versions, you can update from 1.x without any other changes or recompilation needed.
