Oct 1, 2025October 2025 (2025-10) monthly summary for likec4/likec4: Delivered a set of UX, reliability, and architecture improvements that enhance onboarding, configuration safety, and developer velocity. Key features delivered include a Landing Page Revamp with responsive design and new navigation, plus a New Landing Page asset. Added a 6-month share expiry option and logo. ModelSchema was enhanced with strict object validation and additional project fields. Config validation was tightened with a stricter JSON schema to prevent invalid configs. Quality and reliability improvements included E2E tests updated to run with a light theme and corrected export URL paths, and error handling and logging added to filesystem operations. Release management progressed with v1.42.1 and v1.43.0 releases, plus updates to dependencies (Motion and Vite) and pnpm, and grouping Cloudflare packages in Renovate. Overall impact: stronger product safety, better user experience, and faster release cycles. Technologies/skills demonstrated: TypeScript refactors, JSON schema validation, E2E testing, theming and UI redesign, build tooling upgrades, and observability improvements.

Aug 1, 2025August 2025 delivered a redesigned navigation panel with search, folder navigation, and editor controls, plus a Dynamic View Walkthrough and panel-level view insights. Cleared technical debt and strengthened scalability by migrating to a multi-project architecture, implementing project reloading, and stabilizing UI with style and dependency updates. Achieved notable performance improvements in the diagram flow, upgraded core tooling (TypeScript, Playwright, Graphviz wasm), and laid groundwork for continued releases (v1.35.0 through v1.38.x). Business value: improved navigation UX, faster rendering, and scalable multi-project workflows.

Jun 1, 2025June 2025 performance summary for likec4/likec4. This month delivered a major refactor to strengthen type safety across the codebase, including migration to scalar/branded types, stage-based generics, restructured predicates, and updates to type definitions and the generator. A backbone Type Definitions and Import Path Refactor streamlined core/types usage and import paths while separating base/types from auxiliary logic. API enhancements broadened model querying capabilities with isTagged and improvements to elementsWhere/relationshipsWhere, along with metadata handling improvements (hasMetadata). RichText and markdown capabilities were unified across the system, introducing the RichText class and standardizing descriptions as MarkdownOrString with improved rendering. Diagram tooling and VSCode integration were optimized for performance (QueueGraphvizLayoter, generic LayoutResult) and improved diagram previews. CI/CD and e2e pipelines were restructured for reliability (CI workflow optimization, pnpm->npm migration, e2e config refinements), complemented by multiple releases (v1.32.0, v1.32.1, v1.33.0) and build-quality improvements.
