Release Notes - v1.0.1

Release Date: 2026-04-18
Changes: v1.0.1.dev3 → main

Summary

Cognee 1.0.1 fixes front-end compatibility issues on case-sensitive filesystems, updates dependency versions and lockfiles, and documents a new Claude Code memory plugin in the README. This release focuses on cross-platform robustness and developer ergonomics while keeping runtime behavior stable for end users.

Highlights

• Fixed front-end file/directory naming so the UI builds correctly on case-sensitive filesystems (Linux and some CI systems).
• README updated with instructions for the Claude Code memory plugin—enables persistent memory for Claude Code sessions.
• Dependency and lockfile updates (nltk, mcp, Poetry/uv lockfiles) for improved stability.

Breaking Changes

• UI path renames: Several frontend files and directories were renamed from PascalCase to lowercase (e.g., src/ui/App → src/ui/app, src/ui/Icons → src/ui/icons, src/ui/Layout → src/ui/layout). If you have any local branches, patches, or external projects that import these paths, you must update those import paths to the new lowercase paths.
• Git note for maintainers: On case-insensitive filesystems (most macOS defaults, some Windows setups) Git may not detect case-only renames. If you encounter issues after pulling these changes, either reclone the repo or manually rename the affected files (git mv via an intermediate filename) to ensure your working tree matches the repository.

New Features

• Documentation: Added Claude Code plugin details to README, including setup steps and the plugin repository path (integrations/claude-code in the integrations repo). This makes it easier to enable persistent session memory for Claude Code users.

Improvements

• Front-end UI files and folders renamed from PascalCase to lowercase (for example: src/ui/App → src/ui/app, src/ui/Icons → src/ui/icons, src/ui/Layout → src/ui/layout) to avoid import/build failures on case-sensitive filesystems.
• Updated dependency metadata and lockfiles (poetry, uv.lock, poetry.lock and project pyproject changes) and bumped key packages such as nltk and the mcp package to newer versions.
• Code formatting applied to tools/simulate_agent.py for consistency (ruff).

Bug Fixes

• Resolved issues where the frontend could fail to build or run on case-sensitive environments by renaming UI directories and files to lowercase.
• Various lockfile fixes to ensure consistent install behavior across environments.

Technical Changes

• Large dependency and lockfile updates (uv.lock, poetry.lock) to align with updated package versions—expect changes in installed transitive dependencies; run your usual dependency install/update commands (poetry install / pip install) after upgrading.
• Bumped mcp package version in cognee-mcp, and bumped nltk version.
• Minor formatting and tooling adjustments (ruff format applied to tools/simulate_agent.py).
