1.8.6 (2026-02-05)
Features Added
- Enable live metrics by default
(#44902)
Breaking Changes
- The default sampling behavior has been changed from ApplicationInsightsSampler with 100% sampling (all traces sampled) to RateLimitedSampler with 5.0 traces per second. This change significantly reduces telemetry volume for high-traffic applications and provides better cost optimization out of the box. Impact: Applications with more than 5 requests per second will see fewer traces exported by default.
(#44925)
Other Changes
- Add missing copyright headers and ensure consistent formatting across files.
