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.
