25.10.0

TL;DR: Symbolicator migrated to distroless images for better security. We've completed the Celery replacement by removing cron and worker containers, and consolidated Snuba consumers into the Event Analytics Platform dataset. No configuration changes required.

Symbolicator Now Uses Distroless Images

We've migrated Symbolicator from Debian to distroless base images. These streamlined containers strip away unnecessary components like package managers, shells, and other OS distribution elements – enhancing security by reducing the attack surface.

Container Consolidation & Dataset Migration

Following last month's announcement, we've now removed the cron and worker containers entirely – taskbroker and taskworker handle everything. We've published comprehensive scaling documentation to help you optimize these services for your workload.

We've also retired the snuba-spans consumer in favor of three focused replacements: process-spans, process-segments, and snuba-eap-items-consumer. This consolidation routes most products (errors, spans, uptime monitoring, and logs) into the Event Analytics Platform (EAP) dataset – making cross-product correlation faster and more efficient.

Other Notable Changes

• Reference architectures: We've added a new Reference Architectures section to the documentation to help you plan and scale your deployment.
• Enhanced data scrubbing: Relay now automatically scrubs otp and two_factor as sensitive values (PR #5250).
• Trace waterfall cleanup: We've removed the "No instrumentation" placeholder from trace waterfalls (PR #101408).
• Pre-release features: Looking to experiment? Check out Native OTLP Ingestion (#3830) and Trace Metrics (#3993) – both available for early testing on self-hosted instances.
