Thanks for putting this up, Colin.
- verified mds and signature
- ran "mvn install" without test failure
- ran "mvn package -Pnative" without test failure in htrace-c
- built src tarball by running "mvn clean install -DskipTests
assembly:single -Pdist"
- launched htraced and sent test tracing spans by HTracedRESTReceiver
and checked the spans by Web-UI
I'm +1 if the issue about NOTICE.txt Lewis pointed out is not critical
for release.

I've posted the first release candidate here:
http://people.apache.org/~cmccabe/htrace/releases/4.0.0/rc0
The jars have been staged here:

There's a lot of great stuff in this release, including a new web UI,
many bug fixes, API improvements and enlargement of span IDs to 128
bits to avoid conflicts.
The vote will run for 5 days.
cheers,
