v1.2.1 — Reliability & Search Improvements

Release Date: 2026-06-21
Changes: v1.2.1 → main

Summary

This patch release focuses on making Cognee more reliable and faster for everyday use. It improves search relevance and indexing robustness, fixes several syncing and UI issues, and trims query and ingestion latency so results appear faster.

Highlights

• Search relevance updates that return more helpful results for common queries.
• More robust ingestion and background sync so your added content is indexed reliably.
• Lower query latency — searches and retrievals complete faster in typical workloads.
• Multiple bug fixes in the web app and SDK for smoother day-to-day use.

New Features

• Improved search tuning: Adjustments to how search ranks results so common queries return more useful items first — this helps you find the right document or memory faster without changing how you work.
• Indexing status indicator: The UI now shows a clearer status when new content is being indexed (a dataset is a collection of documents or notes you add). This makes it easy to know when newly added content is searchable and avoids confusion about missing results.

Improvements

• More resilient background sync: The background processes that keep your local changes and the server index in sync have been hardened, reducing dropped or delayed updates so new items appear in search reliably.
• Better error messages in the UI: When something goes wrong (for example when ingestion fails), the app shows clearer, actionable messages so you can fix problems faster.
• SDK stability improvements: The SDK recovers more gracefully from transient network issues, reducing unexpected failures for integrations and scripts that interact with Cognee.
• Cleaner search previews: Search result snippets are trimmed and highlighted more consistently so you get a clearer preview of matched content.

Performance

• Faster query latency: Typical search and retrieval times are reduced, so interactive lookups and chat-style queries feel snappier.
• Faster ingestion for medium-sized uploads: Uploads and initial indexing of common file sizes complete more quickly, reducing the wait time before content becomes searchable.

Security

• Dependency updates: Upgraded several third-party libraries to their latest stable releases to reduce exposure to known issues and benefit from upstream fixes.

Bug Fixes

• Fixed an issue where newly uploaded content sometimes did not appear in search until a manual refresh.
• Resolved a sync edge-case that could cause duplicate index entries for a small number of items.
• Fixed UI rendering glitches on smaller screens so dialogs and status indicators display correctly.
• Addressed an SDK error that could surface during intermittent network failures, preventing unexpected crashes in client code.
• Fixed inaccurate progress reporting during large file ingestion so the progress bar better reflects real work left.
• Resolved occasional timeout errors during bulk deletes.

Technical Changes

• Refactored core indexing internals to simplify maintenance and reduce risk of future bugs (no user action required).
• Improved logging and observability so operators can diagnose indexing and query issues faster.
