September 2025 monthly summary for KittyCAD/modeling-app focusing on API endpoint correctness and naming consistency in Text-to-CAD integration.

June 2025 monthly summary for KittyCAD/modeling-api. Focused on improving animation timing precision by upgrading the duration_seconds type from f32 to f64, delivering a more accurate and stable animation timing representation across the API. This change reduces numerical drift and lays groundwork for more reliable playback and scheduling in downstream features.

May 2025 performance summary for KittyCAD/modeling-api. Delivered observability and debugging enhancements and completed routine release housekeeping, setting the foundation for scalable debugging and reliable builds.

April 2025 monthly summary for KittyCAD/modeling-api: Delivered the 0.1.5 release bump for KittyCAD Modeling Session, updating Cargo.toml and Cargo.lock to ensure deterministic builds and versioning parity for downstream consumers. This release focuses on packaging discipline and prepares the ground for upcoming features by stabilizing the build metadata and dependencies.

March 2025 monthly summary for KittyCAD/modeling-app focused on stabilizing the test environment and preventing resource leaks. Delivered a critical test teardown fix to close websocket connections after tests, reducing resource leaks and improving CI reliability. This work eliminated cross-test contamination and contributed to faster, more predictable feedback for developers.

February 2025 — KittyCAD/modeling-app: Focused on delivering a foundational dependency analysis capability to improve build performance and maintainability, with no major bugs documented as fixed this month. The work establishes a scalable path for dependency-aware compilation and parallel processing, along with robust cycle detection to prevent problematic import graphs.

January 2025: Focused on extending AST tooling to support external integrations. Key delivery includes a public AST traversal API and utilities, exposing visitor and walker modules, and a new Node::ptr_eq helper to enable robust cross-pass traversal. These changes establish a foundation for modular AST processing and enable downstream crates to leverage KCL AST capabilities, improving extensionability and ecosystem leverage.

December 2024: KittyCAD/modeling-app delivered AST robustness and incremental build enhancements that improve change-detection accuracy and reduce rebuilds. Key features delivered include AST Digest and Traversal Improvements and Program Generation Caching and Incremental Update. Commits driving these changes include 7ed26e21c6f106d70f55bc3d9d845a5bce0e0270 (More Walk cleanup), 6ff8addc8ba0570ea4905978005489885e1bfd3c (Remove non code from Digests), and d535a2862d9685989dd295f6a5ff97ef3e59d23b (Implement some basic cache program generation). These changes enhance the robustness of AST-based hashing, enable selective scene rebuilding via caching, and establish groundwork for faster iteration and scalability.

2024-11 Monthly Summary: Focused on improving code quality and maintainability for KittyCAD/modeling-app by introducing a lint rule that enforces explicit use of offsetPlane when defining a non-default origin in startSketchOn. This targeted rule reduces ambiguity in plane definitions, promotes consistent coding patterns, and supports safer onboarding for new contributors.
