Full Changelog: v1.0.0...v2.0.0

v1.0.0

This version introduces breaking changes and improvements. There is no special significance behind the version number, the shift to v1.0.0 reflects breaking changes and new feature updates.

Breaking Changes

  • API Update: Major updates to the tracer API. This may require modifications to existing integrations. #131 by @dmehala
  • Separation of public and private headers: Public and private headers have been reorganized, leading to a cleaner structure. Public headers are now located in include/ directory. #144 by @dmehala

What's Changed

  • Bug Fix: Trimmed inspected headers to improve performance and accuracy. #137 by @dmehala
  • New Feature: Ensured that tracecontext headers take precedence over Datadog headers (AIT-10281). #142 by @zacharycmontoya
  • Refactor: Refined Remote Configuration support to enhance stability. #130 by @dmehala
  • Dependency Update: Bumped libcurl to version 8.8.0. #135 by @dmehala

New Contributors

We are thrilled to welcome the following new contributors to the project:

  • Datadog/W3C interoperability: This enhancement prepare ground for better interoperability between Datadog and W3C Tracecontext propagation style. #115 by @dmehala
  • Remote Config Sampling Rules: This feature adds support for remote configuration of sampling rules, providing more control over how traces are sampled. #116 by @dmehala
  • Expose Numeric Tags: This enhancement allows users to set numeric tags, providing greater flexibility and insight into your trace data. #111 by @Anilm3
  • Report Host Information: Host informations are now included in telemetry reports, enhancing the granularity and utility of collected data. #118 by @dmehala

Bug Fixes

  • Glob Matching: Fixed an issue with case sensitivity in glob matching, ensuring consistent behavior across tracers. #112 by @dmehala
  • Remote Configuration polling interval: Resolved a bug allowing DD_REMOTE_CONFIG_POLL_INTERVAL_SECONDS to accept floating-point input, allowing sub-second polling interval of remote configuration. #123 by @dmehala
