Release Notes - v0.5.7

Release Date: 2026-04-03 Changes: v0.5.7 → main

Summary

Cognee 0.5.7 focuses on making memories faster, more accurate, and easier to work with. This release improves search relevance and sync speed, adds richer attachments and sharing options, and fixes a number of reliability issues—while introducing one important format change for memory exports.

Highlights

• Significantly improved semantic search relevance and speed
• Support for multi-file and richer attachments inside memories
• Workspace sharing and access controls for smoother collaboration
• Faster initial sync and reduced memory footprint on clients
• Important export format change (breaking) — see Upgrade notes

Breaking Changes

• Memory export format updated to v2: The JSON shape for exported memories has changed (field names and structure). If you use automated imports/exports or third-party tools, update them to handle the new export format. We provide a compatibility tool for converting v1 exports—run the migration or re-export from the app.
• API note: Some internal API fields used by integrations were renamed; most official SDKs have been updated. If you maintain a custom integration against the internal API, please update to the latest SDK or review the API change log.

New Features

• Multi-file attachments: You can now attach multiple files (documents, images, PDFs) to a single memory and view previews inline—making it easier to store and recall context-rich items.
• Workspace sharing & roles: Share memory collections with teammates and assign basic roles (viewer/editor) to control access without leaving the app.
• Memory undo for deletes: A 30-day “trash” holds deleted memories so you can restore them if removed by mistake.

Improvements

• Search relevance and ranking: Updated embedding and re-ranking logic yields more accurate search results for short and long queries; users will notice more useful top results.
• Faster initial sync: Clients now perform a smaller, prioritized sync on first startup, reducing time-to-usable.
• Reduced client memory usage: Background caching and lazy-loading reduce RAM use for large workspaces.
• Improved attachment handling: Previews and faster uploads for common file types; larger file uploads are handled more robustly.
• UI polish: Cleaner memory list, clearer breadcrumbs, and improved empty-state guidance to help new users get started.

Bug Fixes

• Fixed intermittent duplicate memories appearing after sync completion.
• Resolved an issue where long-running searches could time out and return stale results.
• Fixed auth token refresh bugs that caused unexpected logout for some users.
• Corrected broken links in shared workspace invites and resolved inconsistent permissions display.
• Resolved a crash when saving very large attachments in some browsers.

Technical Changes

• Storage refactor: Server-side storage layer refactored to improve scalability and prepare for sharding. This should be transparent to users but reduces future downtime risk.
• Dependencies upgraded: Key backend libraries updated for performance and security improvements.
• Telemetry improvements: Better instrumentation for search and sync to help diagnose future issues faster.
