v1.2.2.dev4 — Stability & Quality Improvements
Release Date: 2026-07-07
Changes: v1.2.2.dev4 → dev-release-v1.2.2.dev4
Summary
This development release focuses on stability, bug fixes, and small usability improvements. It does not add large new features but makes the platform more reliable and faster for everyday use.
Highlights
- Stability fixes that reduce crashes and data indexing errors
- Improved ingest and search performance for larger collections
- Small UX and API polish to make common workflows smoother
New Features
- No major new features in this dev release: the focus is on stability and quality rather than new capabilities.
Improvements
- Cleaner dataset handling: Fixed several edge cases around dataset (a collection of documents or notes you add to Cognee) creation and deletion so datasets no longer appear empty or fail to load unexpectedly.
- Smoother ingestion feedback: When you upload documents, the UI and API now give clearer progress and error messages so you know what succeeded and what needs retrying.
- Search relevance polish: Small adjustments to ranking and filtering make search results more relevant for common queries, so you find the right memory or document faster.
- API response consistency: The public API now returns more consistent fields and error codes for common operations, reducing surprises when integrating with automation or scripts.
Performance
- Faster ingestion for large files: Bulk uploads and large-document processing use less memory and complete faster, which shortens wait times when adding many documents.
- Reduced search latency: Query paths and indexes were optimized to lower response times for typical lookups, improving interactive responsiveness.
Security
- Dependency updates: Several third-party libraries were updated to their safer, supported versions to reduce exposure to known issues (no CVEs introduced or called out in this release).
- Improved input validation: Better checks when accepting uploaded documents and metadata to reduce the chance of malformed data causing crashes.
Bug Fixes
- Fixed a crash that could occur when ingesting malformed or partially-corrupted documents so ingestion now fails gracefully with a clear error.
- Resolved an issue where recently-deleted items could still appear in search results until a manual refresh; deletion is now reflected reliably.
- Corrected timestamp and ordering inconsistencies for newly added memories so recent items show up in the expected order.
- Addressed several user-interface glitches that affected progress indicators and status messages during long-running jobs.
Technical Changes
- Internal refactors to indexing and ingestion code to reduce duplication and make future fixes simpler.
- Expanded automated test coverage around dataset lifecycle and search behavior to catch regressions earlier.
