Released: 15 Apr 2026

AIDB 7.3.1 includes the following enhancements and bug fixes:

TypeDescription
EnhancementPipeline DLQ — Phase 3: Metrics and error log API: Expanded the Dead Letter Queue with a metrics and error log API, providing programmatic access to per-pipeline error counts, error details, and historical error logs.
EnhancementMulti-user pipeline PGD trigger wrappers: Added multi-user aware trigger wrappers for PGD pipelines, ensuring that pipeline auto-processing triggers work correctly in multi-user PGD environments.
EnhancementPGD custom operand images: PGD pipeline deployments can now use custom operand images, allowing user-defined container images to be used for AI model execution in distributed environments.
EnhancementKnowledge base tables in PGD replication setup: Knowledge base tables are now automatically included in PGD replication configuration during setup, ensuring knowledge base data is replicated across PGD nodes.
EnhancementImproved PDF parsing: Updated the lopdf library to a newer version with improved structural PDF parsing, resulting in better text extraction from complex and malformed PDF documents.
EnhancementHTTP 429 retry handling: AIDB now automatically delays and retries requests that receive an HTTP 429 (Too Many Requests) response from model provider APIs, improving resilience when API rate limits are hit.
Bug fixFix handling of wrong input type errors: Input type validation errors are now caught and surfaced correctly at the input stage rather than propagating as unexpected errors downstream.
