Rspack 2.x is already available in Meteor 3.6-beta.0, so the feedback cycle has started, and we need your help to tweak it towards the official release.
meteor update --release 3.6-beta.0
The migration is automatic, at least to get the basic setup, Rspack 2.x dependencies, and basic configuration compatibility. Just update and run your app. However, your projects may still need to check their own loaders, plugins, and tooling beyond the basic Rspack setup, and understand if they need any transition from Rspack 1.x to 2.x. Check out the release announcement for more information.
Btw, there’s a new version of the AI agent skills with information about the Rspack 2.x migration. That can surely help you have a smooth transition, even if you have some specific requirements.
npx skills@latest add 'meteor/agent-skills#v1.1.0-beta.0'
Please, play with the upgrade and let us know if you see anything off that may require a new default from us, or if your findings could serve as documentation for others facing similar problems when the case is specific to a tool used as part of your build system.
