To get access to the latest and greates Nifty, Snapshots (= Development Versions) are now available at the Nifty Maven Repository I've set up at sourceforge.net.
You can get the latest Snapshot here: http://nifty-gui.sourceforge.net/nifty-maven-repo/lessvoid/nifty/1.1-SNAPSHOT/</a></p>
In case you're using Maven you've probably already using this in your pom.xml:
nifty-maven-repo.sourceforge.net</id>
http://nifty-gui.sourceforge.net/nifty-maven-repo</url>
</repository>
</repositories></pre></p>
You only need to change your nifty dependency to snapshot and you're always using the latest Nifty Build:
lessvoid</groupId>
nifty</artifactId>
1.1-SNAPSHOT</version>
</dependency></pre></p>
Good Luck and Have Fun!
