AIDB 7.3.1 release notes v7
Released: 15 Apr 2026
AIDB 7.3.1 includes the following enhancements and bug fixes:
| Type | Description |
|---|---|
| Enhancement | Pipeline 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. |
| Enhancement | Multi-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. |
| Enhancement | PGD 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. |
| Enhancement | Knowledge 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. |
| Enhancement | Improved 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. |
| Enhancement | HTTP 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 fix | Fix 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. |
