Granite Data Services 2.3.1 GA is out and available for download here. Maven artifacts have been uploaded and should be shortly available as well.
This new version is mainly a bufix release after the previous 2.3.0.GA. The full change log can be found on GraniteDS' Jira here.
For those of you who are using GraniteDS' Builder or Wizard (see this blog post about this great new tool), our update site also features the last version bundles.
