lightstep-tracer-c++-0.5.0
- Adds an option
use_single_key_propagation
to support Injecting/Extracting span context using only a single key/header. - Allows for more efficient propagation by making use of
opentracing::TextMapReader::LookupKey
. - Removes the git submodule, so that releases will package all of the code necessary to build.
