First of all, the community (that’s YOU!) has been fantastic over the last two weeks. Thanks for helping with questions, comments and remarks making Neo4j better – keep it up!
Forwarding address: https://github.com/Neo4j
We’ve packed up and moved our source repositories over to GitHub, now living at https://github.com/Neo4j. While settling into our new digs, we’ve re-arranged things into multi-module projects with top-level parents that make checking out and building a bit simpler.

Re-arranging the furniture
Our components are now in the same room together, easy to grab and build if you want to work from the source. What’s in that room? Neo4j 1.3.M02 now contains:
Also, note that the version numbers of all core components now match the release – 1.3.M02 – dropping the previous prefixing of distinct component version.
New backup library
Taking advantage of the High Availability communication features, we’ve re-implemented the Neo4j backup library. Both incremental and full backups are now pretty simple, just borrow this little code snippet:
GraphDatabaseService db = new EmbeddedGraphDatabase("db");
OnlineBackup.from( "localhost" ).full( "backupdir" );
OnlineBackup.from( "localhost" ).incremental( "backupdir" );
The server’s Webadmin UI has been spruced up, we’ve added a bit of spit-n-polish to repair some blemishes and bashed out some small dents.
Log rotation within the kernel has been significantly sped up, which will improve overall performance especially when small transactions are executed.
High Availability setup improvements
There have been a number of efforts being done to wrap the HA setup of Neo4j in different environments. Andreas Ronge has done a great job exposing a simple interface in the HA scripts for Neo4j JRuby and there are now some really useful Chef and Vagrant recipes
Upgrade to Gremlin 0.7 in the server
Our good friend, the graph cruncher Marko Rodriguez, has a revamped Groovy-based incarnation of the Gremlin graph language – an easy way to describe graph operations on top of the Groovy scripting language. With this, you can do supercool stuff on graphs directly in the Webadmin tool, check the state of your graph, or prototype stuff.
That’s all for now, and let us know any comments, issues or thoughts you have!
