lwf added custom tags to riemann-tools, as well as riemann-diskstats.
Derek Perez added Redis, Haproxy, and Cloudant monitors to riemann-tools, plus countless other commits. Rock on, man!
Carl Yeksigian of Blue Mountain Capital published a C# client.
Jake Luciani of Blue Mountain Capital contributed a Cassandra watcher.
Ben Black contributed streams for fast reduction of events and metrics over time, experimented with integrating Parallel Colt, and suggested windowing API ideas.
Gareth Rushgrove made it easier for folks to get started with Riemann-dash by fixing typos, adding 1.8 compatibility, and writing a puppet module.
Edward Ribeiro refactored riemann-java-client's reporting and helped find bugs in riemann-java-client's rewrite.
Derek Perez wrote a node.js client
Joeseph Abrahamson, of Reify Health, wrote an Erlang client: Zeta.
Joe Caswell added FreeBSD and Darwin support to riemann-health.
Michael Klishin (antares) helped get Riemann's build process up to speed with Leiningen 2.
Michael Bernstein (mrb) got Riemann running on Clojure 1.4 and Lein2.
Brian Shumate corrected a non-portable shebang line.
Jeremy Carroll pointed out my evil lies in the configuration guide.
Michael Fairley added a hostname override to RiemannReporter.
Edward Ribeiro improved concurrency in the Java client and fixed lots of little bugs, misphrasings, and typos.
Tom Crayford pointed out a typo.
Benjamin Anderson (banjiewen) wrote a new Python client.
Steve Losh (sjl) wrote streams/fill-in-last and polished several rough edges in common, streams, and periodic. Steve also expanded the adjust stream to take a function which arbitrarily transforms entire events.
Mårten Gustafson started work on the Java client, added timeouts, and tests.
Paul Butcher fixed a typo in the quickstart.
Obfuscurity and Lusis contributed ideas for HA failover and peer discovery.

Eric Lindvall (lindvall) updated riemann-ruby-client to be 1.8-compatible.
#flatland, #clojure and #leiningen, including jodaro, ninjudd, raynes, and amalloy, helped with protobufs parsing, leiningen, and general Clojure questions.
Showyou, my employer, gave me the infrastructure I needed Riemann for, and the chance to share it with the world.
John Mullerleile (jrecursive) was deeply involved in talking through the concept and structure of Riemann, as well as advice around the JVM and profiling.
C Scott Andreas (cscotta) and the Boundary crew gave many helpful suggestions around the JVM, Maven, high_scale_lib, and profiling. Our conversations yielded many references, algorithms and ideas.
Allen Rohner (arohner) on #clojure offered a logging configuration snippet.
Ryan Grove and Sean Cribbs gave feedback on documentation and design.
Reid Draper contributed a syntactic patch.
Sam Newman (snewman) brought Riemann up to speed with Clojure 1.3.
