Awesome, thank you!

[vivekkothari]

can you release it to maven central?

[benjamin-bader]

Yes, but it will have to wait until later this week - I've switched machines since the last release, and need to re-discover some Maven incantations that will get it done. For now though, it's bedtime here in California.

Thanks again for your contribution!

Version 0.9.1-1 has been pushed to Maven Central, and should be available within an hour or so.

[vivekkothari]

There seems to be something wrong with the artifact on Maven.
http://mvnrepository.com/artifact/com.bendb.dropwizard/dropwizard-redis/0.9.1-1
Also It does't have my changes. Can you please check?

[benjamin-bader]

I downloaded and decompiled the jar from the link you posted, and the extra metrics you added in this PR are definitely there. Are you sure that you're pulling the new version into your project?

What other problem are you seeing?
