 ## [Unreleased]
 
+## [2.30.0] - 2026-03-19
+
+### Added
+
+* Core: Enable `libdatadog`-based features and tests on macOS ([#5351][])
+* Tracing: Add `_dd.p.ksr` propagated tag to transmit Knuth sampling rate for backend resampling ([#5436][])
+* Tracing: Integrations: Add `DD_TRACE_<INTEGRATION>_DISTRIBUTED_TRACING` environment variables to control distributed tracing per integration ([#5396][])
+* Profiling: Add profiler setting `experimental_use_system_dns` to use system DNS resolver (defaults to true) ([#5425][], [#5449][])
+* Profiling: Allow lowering CPU profiling sampling interval with `experimental_cpu_sampling_interval_ms` setting ([#5424][])
+
+### Changed
+
+* Core: Enable process tags by default by setting `DD_EXPERIMENTAL_PROPAGATE_PROCESS_TAGS_ENABLED`, expanding tag collection for Tracing, Database Monitoring, Data Streams Monitoring, Profiling, Runtime Metrics, Process Discovery, Remote Configuration, Telemetry, Dynamic Instrumentation, and CrashTracking ([#5432][])
+* Core: Upgrade `libdatadog` dependency to version 29.0.0 ([#5274][], [#5461][])
+* Core: Remove dependency on `pkg-config` system tool for native extension builds ([#5469][])
+* Profiling: Improve profiling error message when another profiler is present ([#5375][])
+
+### Fixed
+
+* Tracing: Integrations: Fix `endpoint_render.grape` ActiveSupport notification instrumentation for `grape` 3.x ([#5414][])
+* Tracing: Integrations: Fix compatibility with `dalli` version 5.x and later ([#5435][])
+* Dynamic Instrumentation: Fix JSON serialization failures when snapshots contain binary data and invalid UTF-8 strings ([#5434][])
+* Dynamic Instrumentation: Show ERROR probe status when custom serializers produce non-JSON-encodable data instead of silent failures ([#5448][])
+* Data Streams: Fix Data Streams Monitoring to correctly report the configured environment instead of showing `env:none` ([#5427][])
