Important behavior changes in this release
If you use the OpenTracing API, the OpenTracing compatible tracer will no longer be returned from OpenTracing\GlobalTracer::get automatically. See #899 or the documentation for more details.
On PHP 7, dd_trace will no longer work on internal functions e.g. curl_exec; use dd_trace_method or dd_trace_function instead. Additionally, when targeting internal functions they also need to be added to the environment variable DD_TRACE_TRACED_INTERNAL_FUNCTIONS which is a comma separated list e.g. DD_TRACE_TRACED_INTERNAL_FUNCTIONS=array_sum,mt_rand,DateTime::add. These two changes enable a significant performance optimization.
