Highlights

Here are some important changes introduced in 2.11.0 and we recommend upgrading.

  • Remove peer services by default. This change is to ensure compatibility with Inferred services, allowing for automatic discovery of instrumented dependencies such as databases, queues, or third-party APIs. If you need the previous peer service behavior back, set the environment variable DD_TRACE_PEER_SERVICE_DEFAULTS_ENABLED=true.

  • Fix a memory leak issue for Runtime Application Self-Protection (RASP)

GVL Profiling is now enabled by default on Ruby 3.2+

GVL profiling means the profiler gathers information from threads waiting to acquire the Ruby "Global VM Lock" (GVL).

This waiting can be a big a source of latency for Ruby applications: a thread "Waiting on the GVL" is a thread that's ready to make progress, but can't start because Ruby is busy doing something else.

For more details on why GVL profiling is relevant, check out How the Ruby Global VM Lock impacts app performance and #3929.
