Hi! The team are pleased to announce our latest release of Narayana - the premier open source transaction manager. The release notes for this version may be found over here: https://issues.jboss.org/secure/ReleaseNote.jspa?projectId=12310200&v... The particular improvements we have addressed in this release should make it much easier to run Narayana's transactional driver inside Tomcat. If you would like to try that you can take a look at our quickstarts over here: https://github.com/jbosstm/quickstart/tree/master/transactionaldriver-and... and https://github.com/jbosstm/quickstart/tree/master/transactionaldriver-jpa... As normal, the release may be downloaded from our website; http://narayana.io/ This version is not available as part of WildFly yet but if you want to build a version of WildFly that uses this version of Narayana you can clone WildFly and build that with the option: -Dversion.org.jboss.narayana=5.6.2.Final For SpringBoot users, provide the following property in your applications pom: <narayana.version>5.6.2.Final</narayana.version> Best wishes, The Narayana Team
