February 2026: Delivered initial OTTL Expression Parsing and Evaluation Library for DataDog/saluki. Implemented lexer, parser skeleton, and EBNF grammar documentation to enable parsing and evaluating OTTL expressions. This release establishes the foundation for expression-based filtering and querying in Saluki and sets the stage for future evaluation engine development.

Month: 2025-12 — DataDog/helm-charts deliverables focused on gateway deployment configurability. Implemented Datadog Gateway Deployment Mode Configuration by introducing the DD_OTELCOLLECTOR_GATEWAY_MODE environment variable to control gateway deployment mode. Updated the Helm chart version and changelog to document this enhancement and align deployment configuration with agent deployment workflows. This change provides operators with greater control, reduces configuration errors, and supports more predictable gateway behavior in production. No major bugs reported or fixed this month.

October 2025 monthly summary for DataDog/datadog-agent: Delivered core feature modernization of the OTLP ingestion path in CoreAgent by replacing the deprecated batch processor with an exporter helper and adding batching queue settings for logs and metrics. This work reduces end-of-life risk, improves throughput and reliability, and simplifies future maintenance. Overall impact: smoother OTLP data ingestion, easier upgrades, and clearer configuration for operators.
