# Changelog: [Internal]
In this diff we are adding another serializer, that will receive local sampling profile (in tracing domain), and will record corresponding Trace Events with `PerformanceTracer`.
It encapsulates the logic of transforming list of samples to `"Profile"` and `"ProfileChunk"` trace events, which will be parsed by Chrome DevTools later.
