End-to-end tracing system for http4s.


Add this to your build.sbt:

libraryDependencies += "dev.profunktor" %% "http4s-tracer" % Version

If you would like to have log4cats support add this extra dependency:

libraryDependencies += "dev.profunktor" %% "http4s-tracer-log4cats" % Version

Note: previous versions <= 1.2.1 were published using the com.github.gvolpe group id (see migration guide).
