Release Notes - v1.1.0.dev1

Release Date: 2026-05-13
Changes: v1.1.0.dev1 → dev-release-v1.1.0.dev1

Summary

This development release (v1.1.0.dev1) advances Cognee’s core memory capabilities with smarter semantic search, bulk memory management tools, and major reliability and performance improvements. It also introduces schema versioning and developer-facing SDK improvements; note this is a pre-release intended for testing and early adopters.

Highlights

• New semantic vector-based memory search for better recall and relevance
• Bulk memory export/import and tagging to manage large collections quickly
• Schema versioning and a migration path to prepare for future changes (breaking changes included)
• SDK and web UI improvements for faster workflows and better developer ergonomics
• Performance and reliability boosts to indexing, deduplication, and sync

Breaking Changes

• Memory schema version bump: internal memory schema has changed in ways that are not backward compatible. You must run the provided migration tool or upgrade to a 1.1-compatible client before connecting older data stores. See the migration guide for step-by-step instructions.
• API contract updates: a small set of memory field names and response shapes were adjusted to improve clarity and stability. Update any client code (SDKs or direct API calls) to the 1.1-compatible versions before deploying to production.
• Export file format defaults: default export delimiter/metadata layout was standardized. Existing import scripts relying on the old default may need minor adjustments.

New Features

• Semantic memory search: richer, vector-based matching to retrieve more relevant memories with configurable similarity settings.
• Memory export/import: bulk export to JSONL/CSV and bulk import to move or back up data more easily.
• Bulk editing and tagging: apply tags, edits, or deletions across many memories at once to speed cleanup and organization.
• Web UI enhancements: improved memory list view, inline previews, and richer filter controls for faster triage.
• SDK improvements: clearer typing, async helpers, and improved error messages for more robust developer integrations.

Improvements

• Indexing performance: reduced latency and more efficient updates when adding or modifying memories, improving perceived responsiveness.
• Deduplication and conflict resolution: smarter duplicate detection and safer conflict handling when multiple clients sync the same memory.
• Search relevance tuning: default similarity and ranking parameters adjusted to prioritize higher-quality matches.
• Reliability and logging: improved telemetry and more actionable error messages to simplify troubleshooting.
• Developer experience: clearer SDK docs, upgraded dependency versions, and tighter CI checks to catch regressions earlier.

Bug Fixes

• Resolved an issue that could create duplicate memories during high-frequency syncs.
• Fixed several UI filter and pagination bugs that prevented consistent memory lists for large datasets.
• Addressed edge cases where special characters in memory content could break retrieval or display.
• Corrected serialization/deserialization bugs in SDK clients that could cause failed requests or corrupted exports.

Technical Changes

• Storage refactor: internal storage and indexing layers were refactored to improve maintainability and prepare for future scaling features.
• Dependency upgrades: several core libraries were updated to their newer, supported versions, improving security and compatibility.
• CI and test improvements: expanded unit/integration test coverage and added sanity checks to CI to reduce regressions in future dev releases.
• Telemetry: added more detailed, opt-in telemetry hooks to help diagnose performance and relevance issues during testing.
