1.24.0

All products

Fixed

• Repair the macOS crashtracking sidecar connector #4069
• Avoid leaking a patched module_entry across SSI loader shutdown, which could crash on reload #4087
• Fix vsnprintf off-by-one buffer sizing across appsec/logging/telemetry call sites #4115
• Harden crash-report backtrace collection from a multi-threaded process via ptrace DataDog/libdatadog#2216
• Fix parent-death-signal handling in the sidecar/loader child-process bootstrap DataDog/libdatadog#2348

Internal

• Crashtracker now shares the sidecar's socket instead of holding a dedicated one, reducing per-process file descriptor usage DataDog/libdatadog#2179
• Fix the debug build variant of the SSI loader on PHP 8.4 #4089

Tracer

Added

• Support DD_TRACE_PROPAGATION_BEHAVIOR_EXTRACT (continue/restart/ignore) to control how upstream distributed-trace context is extracted, matching other Datadog tracers #3997
• Add DD_DYNAMIC_INSTRUMENTATION_CAPTURE_TIMEOUT_MS to bound Dynamic Instrumentation capture time #4003
• Add experimental Feature Flag Events (FFE) span enrichment, opt-in via DD_EXPERIMENTAL_FLAGGING_PROVIDER_SPAN_ENRICHMENT_ENABLED (default off) #3996
• Publish standard OTel process and thread contexts from the tracer, consumed by the profiler for runtime identity and effective service metadata #4077

Changed

• Propagate the agent-configured timeout to the sidecar instead of using a fixed value #4025

Fixed

• Scan the agent's full peer-tag key list for client-side stats instead of truncating it, which had started silently dropping tags like out.host/peer.hostname/peer.service/server.address #4102
• Preserve the complete W3C trace-flags byte when converting a Datadog span into an OpenTelemetry span context, fixing sampled+random-id contexts being treated as unsampled #4112
• Fix health metrics over UDS #4116

Internal

• Report OTLP export status (traces/metrics/logs) in the startup log #4056
• Update libdatadog and fix background-sender telemetry errors/flakiness #4073, DataDog/libdatadog#2277

Profiling

Added

• Add build compatibility with PHP 8.6 #4084

Changed

• Avoid an FFI call on the allocation hot path on NTS builds #4068
• Remove indirect allocator forwarding by specializing malloc/free/realloc callbacks at RINIT #4070
• Speed up interrupt_count checks by using a relaxed atomic outside of REQUEST_LOCALS #4074
• Reuse a single cached TSRM pointer for profiler and executor globals in the allocation hook (PHP ≤8.3) #4072

AppSec

Added

• Support the server.response.body.raw WAF address for raw (unparsed) HTTP response body inspection #4055

Fixed

• Ensure _dd.apm.enabled:0 is present on every span so it is reliably encountered during APM-standalone billing processing #4054

Internal

• Report DD_APPSEC_AGENTIC_ONBOARDING in configuration telemetry #4053
