Active Deprecations
The current Vector release is v0.56.0. Deprecated configuration and features are retained for at least one minor release before they are eligible for removal.
compression field in the vector sinkThe boolean syntax (compression: true / compression: false) is deprecated.
Use the string syntax instead: compression: "gzip", compression: "zstd", or compression: "none".
The bool_or_vector_compression deserializer will be removed once the boolean syntax is no longer supported.
series_api_version: v1 option on the datadog_metrics sinkThe series_api_version: v1 option is deprecated in favor of v2 (the default).
The v1 series endpoint (/api/v1/series) is a legacy endpoint.
Users should remove series_api_version: v1 from their configuration or set it to v2.
azure_monitor_logs sinkThe azure_monitor_logs sink is deprecated in favor of the new azure_logs_ingestion sink,
which uses the Azure Monitor Logs Ingestion API.
Users should migrate before Microsoft ends support for the old Data Collector API (scheduled for September 2026).
