What's New
Release notes for the FLUID specification, newest first. Each entry links to the full page and the auto-generated schema diff.
| Version | Codename | Compatibility | Summary |
|---|---|---|---|
| 0.7.5 (latest) | Streaming Kafka → Iceberg Sink & Confluent Tableflow | ✅ Additive over 0.7.4 | Adds an opt-in Iceberg streaming sink on the kafka-connect acquisition pattern (iceberg_sink_enabled, streamingSink, sink_topics, iceberg_catalog_overrides) and the confluent Cloud Tableflow binding platform (environment_id / kafka_cluster_id / confluent_role_arn). |
| 0.7.4 | Runtime agentPolicy Enforcement at the MCP Gateway | ✅ Additive over 0.7.3 | Makes an expose agent-consumable over MCP and turns policy.agentPolicy into a gate the MCP output-port gateway enforces on every read. Adds the optional exposes[].mcp block, the postgres binding platform, and the postgres_table / athena_table / glue_table formats. |
| 0.7.3 | Source-Aligned Acquisition | ✅ Additive over 0.7.2 | Ingestion becomes a first-class FLUID concept: the acquisition build pattern, six ingestion engines, delivery guarantees + DLQ, schema-evolution policy, supply-chain image signing, and a top-level retention block. |
| 0.7.2 | Semantic Truth Engine | ✅ Additive over 0.7.1 | A per-expose semantics block (entities, measures, dimensions, metrics) gives agents and BI tools a verbatim metric definition, plus binding.icebergConfig for Iceberg table specifics. |
| 0.7.1 | Agentic Governance + Provider-First Orchestration | ✅ Additive over 0.5.7 | agentPolicy, sovereignty, root-level accessPolicy, and provider-first orchestration tasks. |
Reading the compatibility column
The 0.7.1 → 0.7.5 line is strictly additive: bump fluidVersion and every prior contract still validates.
0.7.5 continues that streak. It only adds optional fields, enum values, and a wider engine shape, so every valid 0.7.4 contract validates as 0.7.5 unchanged. See What's New in 0.7.5 for the details.
