Canner/WrenAIwren-v0.12.0Jul 6, 2026by github-actions[bot]

AI Summary

This release introduces auto-reindexing capabilities for memory sources and enhances policy governance for table-valued functions across all dialects. It also adds cross-dialect type translation and completes the internal renaming from wren-engine to wrenai. Additionally, numerous bug fixes were implemented to improve SQL string handling and decimal precision across various database connectors.

Key Highlights

  • Added 'wren memory watch' to automatically reindex when source changes are detected.
  • Enhanced policy governance to control data-reading TVFs in all positions and introduced a structure source-func allowlist.
  • Implemented cross-dialect type translation to the type_mapping for better compatibility.
  • Completed the internal refactoring cleanup renaming 'wren-engine' to 'wrenai'.
  • Fixed multiple SQL parsing issues by stripping trailing semicolons before subquery-wrapping in major dialects like Postgres, Oracle, and Redshift.

New Features

  • Auto-reindex on source changes via 'wren memory watch'.
  • Governance for data-reading TVFs and source-func allowlist.
  • Cross-dialect type translation to type_mapping.
