Here’s a peek into what has been happening in Emberland recently, including: a flood of new RFCs and activated RFC features in Ember, Ember try scenarios in Ember CLI, a call to the community to assess their application and much more! 🐹
Two rough patches were smoothed out as well with this PR to treat the lib folder as node files for ESLint purposes, while this PR updated ember-cli to install optional dependencies when creating a new project, fixing a problem for users creating Glimmer.js apps.
Progress was made on the Module Unification front in ember-resolver as two PRs landed to add support for module unification namespaces in glimmer-wrapper (4, 5).
The let template helper RFC (Request for Comments) was finally merged. The helper allows users to create blocks in which properties can be bound to specific values and then used inside the block, all done inside the template. You can read more about its use cases in the full proposal as well as trying it yourself by turning on the ember-template-block-let-helper feature flag in canary. See also the Feature Flags guide for more instructions.
The crucial RFC proposing the splitting of Ember into composable modules has entered the final comment period this week. It’s an important step towards a future where you can install from small-scoped Glimmer to ambitious Ember apps. Also, the RFC for making jQuery fully optional in Ember apps and aiming to reduce overall bundle size of the framework is waiting for the last comments.
On another note, an RFC proposing the deprecation of resetNamespace has been closed this week due to popular use of related features in real-world apps. The resetNamespace API allows you to rename routes arbitrarily, even if their namespace was defined differently by their nesting hierarchy. It lives on and will not be deprecated- for now.

This team is busy turning some legacy pieces of Ember’s public websites into modern Ember apps! For example, check out an incredible, rapid conversion of the statusboard app by @rwwagner90 and ongoing progress on the deprecations app (1, 2, 3, 4) by @serenaf. Missing deprecations are tracked in this related issue.
