v1.4.1.dev0 — Usability & Stability Improvements

Release Date: 2026-08-05
Changes: v1.4.1.dev0 → dev-release-v1.4.1.dev0

Summary

This development snapshot focuses on polish: clearer error messages, more reliable ingestion, and search that returns more relevant results. It also includes backend performance and packaging tweaks to make daily use and upgrades smoother.

Highlights

• Better search relevance and ranking for recent documents
• Progress indicators and clearer errors during data import
• Faster ingestion of large files and lower memory use
• Multiple bug fixes and dependency updates for improved stability

Breaking Changes

• No breaking changes in this development release. Existing projects should continue to work without modification.

New Features

• Improved search ranking — Search now uses broader context when matching queries, so results favor more relevant documents. This helps you get usable answers faster without changing how you search.
• Ingestion progress and clearer errors — When you add documents or upload large files, the system shows progress information and clearer error messages. This makes it easier to see what’s happening during import and to recover from problems.

Improvements

• More informative error messages and logging — Errors now include actionable guidance (what failed and how to fix it) instead of opaque traces, reducing time spent troubleshooting.
• Smoother CLI and tooling behavior — Command-line tools and developer utilities were refined for more consistent behavior across platforms.
• Updated dependency versions — Third-party libraries were updated to improve compatibility and reduce the chance of installation/runtime issues.

Performance

• Faster ingestion for large files — Improvements to the ingestion pipeline reduce the time and memory required to add large documents, letting you load more data quicker.
• Lower query latency — Optimizations in the search path reduce average response time for common queries.

Security

• Dependency updates and stricter input validation — Several dependencies were updated and input handling was hardened to reduce exposure to malformed data. No public CVEs are referenced in this release.

Bug Fixes

• Fixed intermittent crash when importing empty or malformed files.
• Resolved an issue where search results could de-duplicate valid distinct documents.
• Fixed CLI edge-cases where progress display could stall on slow networks.
• Minor UI fixes: layout and text clarity improvements in the web dashboard.

Technical Changes

• Refactored core ingestion modules for better testability and future feature work.
• Improved unit and integration test coverage around search and ingestion logic.
• Packaging and build tweaks to simplify developer installs and local testing.
