February 2026 monthly summary for KittyCAD/modeling-app focusing on business value and technical achievements. Delivered a set of features that improved deployment, modeling workflows, TLS security, and desktop UX, along with a critical bug fix that stabilizes sketch deletion operations. This period strengthened product reliability, security, and developer scaffolding, enabling faster iterations and safer releases.

January 2026: KittyCAD/modeling-app delivered meaningful improvements across modeling accuracy, UX, and CI reliability. Zookeeper UX improvements were implemented to make selections more reliable, add an extra e2e check, and improve scrolling behavior, reducing flaky tests and user confusion. BodyType support was added to Revolve P&C and Loft P&C, enabling more accurate part definitions and smoother downstream simulations. ZDS geometry tooling received enhancements for Split and Flip Surface, and open-path selection in surface lofts, enabling more flexible editing workflows. The Extrude flow gained a prepopulated length argument for faster, fewer-click modeling, complemented by UI polish such as light/dark theme classes for selection boxes and a refined loading UX that only shows on final responses. Release and CI improvements included a FORCE_RELEASE_BUILD flag, forced Zookeeper e2e Fast mode to speed CI, and Linux Chrome flags optimization to stabilize test behavior. Bug fixes and stability improvements included reverting CodeMirror integration to restore React compatibility, restoring balance updates upon prompt success, and fixes to Vercel builds, markdown link handling, Step back for unconfirmed arguments, and scene selection for P&C geometry. These changes collectively raise modeling accuracy, reduce CI/runtime costs, and improve user experience while strengthening release discipline and dependency hygiene.

Month: 2025-12 — KittyCAD/modeling-app monthly wrap-up focusing on UX/stability, streaming UI, and maintenance. The month delivered targeted Zookeeper improvements, UI polish, and essential maintenance that together improved reliability, developer velocity, and business value.

November 2025 performance summary for KittyCAD/modeling-app: Delivered high-impact Copilot enhancements, a major geometry UX refactor, and a series of reliability fixes that improve design throughput and product stability. Key features delivered include Copilot fast mode selection and end-to-end test coverage, plus the Chamfer & Fillet Point-and-Click Refactor to streamline geometry edits. Major bugs fixed include removal of guarded KCL errors to enable direct fixes, in-pipe fillet edit fixes, and shell point-and-click bugs on faces, along with improvements to Extrude To messaging and selection behavior. UX and validation improvements were introduced for Hole UI (vector2d cutAt) and validation checks for Hole and GD&T Flatness. The month also emphasized test infrastructure and maintainability through test fixtures and updater UI polish. Overall impact: faster design iterations, reduced debugging time, and higher release confidence. Demonstrated technologies and skills: end-to-end testing, UI/UX refinements for point-and-click modeling, robust error handling, and maintainable refactors with strong test infra.

October 2025 — KittyCAD modeling-app: Delivered core modeling capabilities, stability hardening, and a safer feature experimentation framework, driving faster time-to-value for users. Key features include extending extrusion targets to caps, walls, and edge cuts; enabling multi-solid Subtract operations; and consolidating feature gating and experimental handling with improved visibility for Text-to-CAD. Reliability improvements include a billing status fix after Text-to-CAD prompts, improved module alias resolution for KCL, and better error messaging for artifacts originating from imported modules. UI/UX enhancements and tests were added for command bar validation and parameter editing, and supplementary fixes (Copilot avatar rendering, browser translation monkey patch) contributed to a smoother user experience. Technologies demonstrated include KCL/UI feature flags, robust error handling, and test-driven development across cross-module changes.

September 2025 performance summary focusing on feature delivery, reliability improvements, and engineering velocity across KittyCAD repos. Delivered security, packaging, and developer experience enhancements while maintaining product quality through test stability and CI/CD improvements.

August 2025 focused on delivering high-value features, stabilizing onboarding UX, and consolidating UI infrastructure for KittyCAD/modeling-app, with strong emphasis on test fidelity and developer workflow improvements. Key work included regenerating the truss structure test fixture to keep test expectations aligned with rendering changes (no production logic changes), enabling point-and-click sweep-face selection on the Offset Plane, centralizing billing UI into the shared library for consistency, and overhauling the Text-to-CAD onboarding UX. A targeted rollback was performed to revert TTC Conversational UX changes when issues were encountered, restoring a stable onboarding state. These efforts, along with related refactors and workflow enhancements, improved product reliability, reduced maintenance costs, and accelerated future iterations.

July 2025 monthly summary for KittyCAD/modeling-app. Delivered a blend of user experience improvements, core modeling tooling refactors, and strengthened testing/infrastructure to accelerate design workflows, improve reliability, and reduce long-term maintenance overhead.

June 2025 monthly summary focusing on delivering scalable modeling workflows, enhancing UX, and strengthening release/test reliability. Key features delivered improved modeling precision and UX with optional-argument flows across core operations; introduced cross-platform download CTA; and implemented traceability and test reliability improvements that reduce risk across builds and releases.
