This is a dependency update. That said, upgrades should be fairly straightforward for most clients.

Available in maven central via:

<groupId>com.twitter</groupId>
<artifactId>hbc-core</artifactId> <!-- or hbc-twitter4j -->
<version>2.0.0</version>

Changes:

• Upgrade JOAuth to 6.0.2 from 4.0.1.
• Removed transitive Scala dependency that was brought in via the previous versions of JOAuth.
• Upgrade Guava dependency to 14.0.1.
• Removed twitter4j 2.x support. The hbc-twitter4j module is now based on twitter4j 4.0.1. Removed the hbc-twitter4j-v3 module as part of this.
