docs/symfony-logs.md) and a full end-to-end example with every processor enabled and OpenTelemetry tracing (docs/advanced-example.md).HttpRequestProcessor, UserProcessor, and EcsUserProvider are now tagged with kernel.reset, so Symfony clears their cached state between requests in worker mode.EcsUserProvider — security.token_storage is now injected explicitly via DI arguments instead of autowiring.CorrelationIdProcessor — new processor that reads a correlation ID from Monolog extra and writes it to labels.correlation_id or trace.id. Works with any library that populates extra (e.g. aubes/correlation-bundle). The source key is removed from extra after processing.TracingProcessor — new opentelemetry mode that reads flat trace_id/span_id/trace_flags keys injected by the OpenTelemetry Monolog processor and maps them to ECS fields. The flat keys are cleaned up from context automatically.monolog.formatter.ecs now produces a different JSON structure: log.level is nested under log and lowercased (was a root-level dot-notation key). Existing Elasticsearch index mappings may need to be updated.AutoLabelProcessor::FIELDS_ALL content has changed: os, vlan, interface, and tracing have been removed; entity (ECS 9.x) and gen_ai (ECS 9.1) have been added. If you reference this constant directly in code, review your usage.AutoLabelProcessor — non-ECS fields are now dropped by default instead of being moved to labels. Add move_to_labels: true to restore the previous behaviour.AutoLabelProcessor — the fields config key is replaced by mode (bundle | full | custom). Use mode: custom with fields: [...] for the previous behaviour of passing a raw list.AutoLabelProcessor::FIELDS_MINIMAL constant removed. Use mode: bundle instead.AbstractProcessor — getTargetField() and support() visibility changed from public to protected. Code calling these methods from outside a subclass will fail.AbstractProcessor — getTargetField() is now final and no longer abstract. Subclasses must pass the target field name as the second argument to parent::__construct() instead of implementing getTargetField().InvalidConfigurationException at container compile time. Previously it silently had no effect.EcsUserProvider — getUserIdentifier() is now mapped to user.name instead of user.id. Symfony's identifier is a login or email (user.name), not a technical database ID (user.id). If you rely on user.id in your index mappings, implement a custom EcsUserProviderInterface.tags config option — static tags added to every log record via the ECS tags field (e.g. ['env:prod', 'region:eu-west-1']). Passed through to the underlying ElasticCommonSchemaFormatter.ecs_version config option — declare which ECS version to output (default 9.3.0). Override for older Elastic Stack deployments (e.g. 8.11.0). Invalid values throw an InvalidConfigurationException at boot.HttpRequestProcessor — injects ECS http.* and url.* fields from the current HTTP request. Optional include_full_url (disabled by default — may expose sensitive query parameters), include_client_ip (disabled by default), and include_referrer (disabled by default — Referer header may carry sensitive external URLs).HostProcessor — injects ECS host.* fields (host.name, host.ip, host.architecture) resolved at boot time. Optional resolve_ip (default false) to auto-detect host.ip via DNS.ErrorProcessor — new map_exception_key option to automatically process Symfony's context['exception'] as ECS error.*.AutoLabelProcessor — new mode option (bundle | full | custom, default bundle) replacing the raw fields list. bundle whitelists fields used by this bundle's processors; full covers all ECS field sets; custom uses the explicit fields list.AutoLabelProcessor — new move_to_labels option (default false). Non-ECS fields are now dropped by default; set move_to_labels: true to preserve them under labels as before.AutoLabelProcessor — new include_extra option to also process non-ECS keys from Monolog's extra array.AutoLabelProcessor — new non_scalar_strategy option (skip | json, default skip). Non-scalar context values are either dropped (skip) or JSON-encoded into labels (json) when move_to_labels is enabled.TracingProcessor — new span_id input key. When present in the tracing array, injects ECS span.id into the log record.processor.user.provider — the referenced service is now validated at container compile time: it must implement EcsUserProviderInterface. Invalid configurations throw at boot instead of silently failing at log time.EcsUserProvider and UserProcessor — both implement ResetInterface for compatibility with FrankenPHP worker mode. State is cleared between requests automatically.AutoLabelProcessor — non-scalar values in non-ECS context fields were previously placed in labels as-is, violating ECS (labels must be scalar). They are now handled via non_scalar_strategy.AutoLabelProcessor — a non-array context['labels'] value no longer throws \InvalidArgumentException at runtime. The invalid value is silently overwritten to preserve ECS compliance.Symfony 7 and 8 compatibility
