Changelog

• pattiesUpdate-available banner + patties upgrade. The CLI prints a cached, channel-aware banner on startup when a newer patties is published, and patties upgrade bumps the project to the newest release on its channel. The banner reads from a local cache and refreshes in the background, so it never blocks; opt out with --no-update-check or NO_UPDATE_NOTIFIER.
• pattiesWorkspace-aware React resolution. The dev-server bin + React resolution are now Bun-workspace-aware, so monorepos with a hoisted root node_modules load a single copy of React and don't crash SSR with "Invalid hook call." Flat-app resolution is unchanged.
• pattiespatties-ui truly optional at the CLI. The catalog commands (add / ui / view / update) are lazy-loaded in the dispatcher, so patties dev / build / deploy / secret no longer fail with "Cannot find module 'patties-ui/schema'" in projects that don't depend on the UI catalog.
• create-pattiesRedesigned scaffolder prompt flow (CLI specs 18 + 19). Coding-agent prompt moves earlier; a new project type (frontend / backend / fullstack) drives gated sub-prompts for Patties UI and monorepo and the deploy-target set. Adds --type, --ui/--no-ui, --monorepo/--no-monorepo, --theme, and a container target (emits a Dockerfile). Claude/Codex projects ship the /patties skill + /patties-init command from one source so they can't drift. Stays zero-dependency.

Framework — patties

• Bun-native runtime. HTTP on Bun.serve, filesystem discovery on Bun.Glob, bundling on Bun.build, dev HMR on bun --hot — no Node-era build stack.
• Filesystem routing + React 19 SSR. Routes compiled to Bun route patterns; pages stream via renderToReadableStream; interactive components opt into being client islands with on-demand hydration.
• Build-time discovery. Route + island discovery runs once at build and is inlined into the production bundle; the server never re-scans the disk at runtime (gated by integration tests).
• Thin context + middleware. Handlers take a standard Request and a small PattiesContext and return a Response; request flow is compose() middleware.
• Adapters. Deploy targets bun and edge behind adapters, keeping platform specifics out of the core.
• Optional AI + plugins + AGENTS.md. Agents, tools, and jobs on a lazy @anthropic-ai/sdk peer dep; plugin hooks for build/dev/jobs; regenerated CLAUDE.md/AGENTS.md app inventory.

Scaffolder — create-patties

• Guided scaffolding. bunx create-patties@latest my-app stamps a working app with a chosen project type, optional Patties UI starter components, optional monorepo layout, and a deploy target — zero runtime dependencies.

UI catalog — patties-ui

• 60 copy-in components. A shadcn-compatible, copy-in catalog; patties add <component> stamps source into app/components/ui/ — never imported from a versioned package. React 19 style (refs as props, no forwardRef), Tailwind v4 + CSS-variable theming, SSR-first with island-by-opt-in.
