Release Notes - v1.0.0.dev0

Release Date: 2026-04-11
Changes: v1.0.0.dev0 → dev

Summary

This is the first developer preview for Cognee (v1.0.0.dev0). It provides the core memory platform foundation — a searchable, structured memory store with a web UI, API access, and SDKs — intended for early testing and integration. Expect experimental APIs and rapid iteration; feedback is welcome.

Highlights

• Initial developer preview: core memory store + web UI
• Public API and SDKs (Python, JavaScript) for programmatic access
• Natural-language search and embedding-backed retrieval
• Improved sync and reliability compared to prototypes
• Export / backup options and basic access controls

Breaking Changes

• This is a developer preview release: APIs and SDKs are considered experimental and may change in future releases. If you build on top of v1.0.0.dev0, be prepared to update integrations when the public stable v1.0.x is released.
• Data model and export format may be updated in future releases. We recommend keeping backups (use the Export feature) and avoiding irreversible production migrations against this dev version.
• Authentication defaults: In this dev preview some auth flows (e.g., API key vs. OAuth) may be enabled or disabled by default depending on install. Check your deployment's auth configuration after upgrading.

New Features

• Core memory store: Save, update, search, and delete memory items with structured metadata and free-text content.
• Web application: A lightweight, responsive UI to browse memories, run searches, and manage collections.
• Public REST API: Programmatic access to create and query memories for integrations and automation.
• SDKs: Official Python and JavaScript SDKs to simplify using the API from applications and scripts.
• Natural-language search: Use plain-language queries to find relevant memories; powered by embedding-based retrieval.
• Export & backup: Download your memory data in standard JSON format for local backup or analysis.
• CLI tool: Basic command-line interface for common tasks like importing/exporting and quick queries (developer-focused).

Improvements

• Search relevance: Better ranking of results by combining keyword matches with semantic embeddings for more helpful results.
• Sync reliability: Reduced risk of duplicate items and improved conflict handling when multiple clients update the same memory.
• Performance: Faster response times for common queries and list operations in the web UI and API.
• Usability: Cleaner UI flows for creating memories, editing metadata, and managing collections.
• Security & auth: Added API key and OAuth support to secure programmatic access (suitable for development and testing environments).

Bug Fixes

• Fixed memory duplication that could occur during rapid repeated saves from external clients.
• Resolved timestamp inconsistencies that sometimes displayed incorrect created/updated times in the web UI.
• Fixed edge-case search regressions where short queries returned no results despite matching content.
• Addressed several UI layout issues affecting smaller screens and narrow viewports.

Technical Changes

• Introduced a plugin-friendly architecture to simplify future integrations (embeddings providers, storage backends).
• Database migrations and initial schema for memory items, collections, and permissions.
• Refactored search pipeline to separate embedding generation from indexing, enabling easier swapping of embedding providers.
• Upgraded several internal dependencies for stability and security; developers should review dependency changes for compatibility in custom deployments.
