Rspack

🚀 Meteor 3.6 is out and is now the recommended release. Here’s what you can try in 3.6: • Rspack 2 with @meteorjs/rspack 3.0.0. Meteor can install compatible build dependencies on the first run when automatic installation is enabled. New React apps start with React 19.2. • Native TypeScript types for Meteor packages. Run meteor types to generate declarations under .meteor/types. Existing apps can keep their current type provider. • Node.js 26.13.0 and npm 11.20.0, plus MongoDB 8.0.29 for local development. • New starters for pnpm workspaces and installable Blaze PWAs. The CLI also gets interactive package selection and shell completion for Bash and Zsh. • A new read-only instrumentation package for observing Meteor methods, publications, and DDP connections. Upgrading an app with an existing local MongoDB 7 database? Back it up and confirm that its feature compatibility version (FCV) is 7.0 while it’s still running on MongoDB 7. Check the platform requirements and rebuild any native npm dependencies against Node.js 26 before deploying.
