 The `main` branch of this repository tracks `InvenTree/master` and may not be compatible with the latest stable release. As it is not tied to an InvenTree release, it is published as `-SNAPSHOT` jars ([browsable here](https://central.sonatype.com/service/rest/repository/browse/maven-snapshots/com/w3asel/inventree-sdk-java/)), which may be consumed by [adding the central snapshot repository to your pom](https://central.sonatype.org/publish/publish-portal-snapshots/#consuming-snapshot-releases-for-your-project):
