• Disable inheritance of the suppression flag from the W3C traceparent: Added a configuration flag to disable inheritance of the suppression flag from the W3C traceparent header, allowing suppression behavior to be controlled independently of the incoming trace context. You can enable this feature by applying the following configuration in the agent configuration file (<agent_install_dir>/etc/instana/configuration.yaml):

  com.instana.tracing:
    global:
      disable-w3c-sampled-flag-inheritance: true

• The PHP tracer now supports sampling through W3C trace context headers traceparent and tracestate when continuing a distributed trace. The PHP tracer captures the OpenTelemetry TraceState sampling threshold value and reports it to the backend when a trace is sampled.

Improvements

• Added support for using * in span filter rules to filter spans based on attribute presence, regardless of the attribute value.

Fixes

• Fixed an issue where span filter configuration in the com.instana.tracing.filter section and stack trace settings in the com.instana.tracing.global section of the agent configuration.yaml file were not applied correctly by the PHP Tracer when used with the instana.disabled_instrumentation INI setting.

Features

• You can control the amount of trace data Instana collects by configuring stack‑trace collection for erroneous spans only, or by disabling it entirely while also setting the stack‑trace depth. For more information, see Configuring stack traces.

Fixes

• Fixes PHP Tracer crash when the /dev/urandom device is not available in Linux environments.

Fixes

• Fixed inconsistencies in W3C trace context propagation in distributed tracing scenarios.

• Use the span kind exit to target HTTP exit spans.
• Exclude pecl_http spans to suppress downstream tracing.

Fixes:

• Span filtering rules based on HTTP response attributes (such as http.status, http.path_tpl, or http.route_id) now correctly retain the PHP root span and all its non‑HTTP child spans in the trace.

Features:

• You can reduce the amount of trace data collected and ingested by Instana by using the span filtering feature with filtering rules that enforce HTTP span attribute conditions. You can customize the filtering rules to exclude spans or traces for irrelevant HTTP endpoints and include those for important HTTP endpoints based on span attributes. These filtering rules give you a finer control over selectively monitoring HTTP endpoints. For more information, see Filtering spans. Use only HTTP span attributesfor filtering. PHP Tracer 5.8.0 and later support filtering with other span categories, types, and attributes.
