About a year ago we moved the raven-java artifacts to a new home under the com.getsentry.raven GroupId. 🎆
All maintenance and future development is going on under the new GroupId. Note that the package names also changed, so imports and class names in configuration (such as logging integrations) will need to be renamed. There shouldn't be any other changes required unless you made customizations to Raven itself, and those should still be minor.
We've made a lot of improvements and bugfixes and have a lot more planned, so check it out when you have time. 😄
The documentation has been improved if you have any questions, or just ask me here!
