Constant Summary collapse

LIB_VERSION =

Current libddprof version

"0.6.0"
VERSION =

The gem version scheme is lib_version.gem_major.gem_minor. This allows a version constraint such as ~> 0.2.0.1.0 in the consumer (ddtrace), in essence pinning the libddprof to a specific version like = 0.2.0, but still allow a) introduction of a gem-level breaking change by bumping gem_major and b) allow to push automatically picked up bugfixes by bumping gem_minor.
