What's New
Introduces strict type-checking and major breaking changes to CLI flags and development configuration management.
Breaking Changes
- Strict type-checking enabled during compilation.
- Renamed `wasp deploy fly` flags (e.g., `--vm-size` to `--db-vm-size`).
- Development ports and URLs are now auto-managed; manual configuration is removed.
- Internal server imports moved to `wasp/server/...` prefix.
- Liveness check endpoint moved from `GET /` to `GET /up`.
New Features
- New `wasp show spec` and `wasp show build` introspection commands.
- Custom APIs now support `PATCH` and `HEAD` HTTP methods.
- `wasp start` supports custom ports and URLs via CLI arguments.
- Ability to run multiple Wasp projects' dev databases in parallel.
- `tsconfig.src.json` options (strict, target, lib) are no longer locked.
Upgrade Notes
Review the [migration guide](https://wasp.sh/docs/0.26/migration-guide) for step-by-step instructions. Update `tsconfig.src.json` and copy the generated `types` directory in Dockerfiles. Ensure Fly CLI 0.4.82+ or Railway CLI 5.28.0+ is installed.
