⚠️ Breaking Changes

Remember to check out the migration guide for step-by-step documentation on how to upgrade.

• The Wasp TS config (main.wasp.ts) is now called the Wasp Spec, and it should import from @wasp.sh/spec instead of wasp-config. (#4153)
• Wasp now requires vitest to be listed in your project's devDependencies. (#4182)
• Removed wasp new:ai and the ai-generated starter template. (#4280)

🎉 New Features

• The api export from wasp/client/api is now a Ky instance instead of Axios for improved performance and smaller final size. (#3998)
• Wasp TS spec now properly sets the NODE_ENV environment variable depending on which command you use to run Wasp. (#4087)
• Added a type-safe NavLink component, mirroring react-router's NavLink API (with isActive, isPending, isTransitioning render-prop helpers). (#4104)
• Wasp TS spec now supports real JS imports, letting you import values in main.wasp.ts and pass them directly instead of using import objects like { import, from }. (#4143)

🐞 Bug fixes

• Fixed a race condition in development mode that could potentially load the app's JS bundle before the Vite runtime, causing the app to fail the load with a "Can't detect preamble" error. (#4258)
• Fixed wasp deploy railway launch sometimes producing a crashed server with an empty DATABASE_URL. Wasp now waits for the database service to finish deploying before setting up the other services. (#4291)
• Fixed a bug where wasp deploy railway launch wouldn't correctly build the Wasp app client if the / route was not prerendered. (#4293)

🔧 Small improvements

• Wasp now also validates tsconfig.wasp.json and the root tsconfig.json in TS spec projects, and tsconfig validation errors now mention which tsconfig.*.json file caused them. (#3911)
• The npm package now shows a clear error when installed on an unsupported Node.js version. (#4268)

📖 Documentation

• We now have a SEO & GEO optimization guide. (#4264)
