We decided in the Tooling team meeting today to deprecate heimdalljs in ember-cli and hopefully remove it in ember-cli@7 🎉
This needs a RFC to be written and someone to implement the deprecation itself. Do you want to help out? Please get in touch!

I made a smol ember app demo: github.com/NullVoxPo...
it only requires 3 files ( 4 for ergo ):
- the html
- babel.config
- vite.config
- ( src/app.gts )
The rest is config for editor tooling 🙈

After months of fragmented effort, I finally published the prototype omni-REPL for web frameworks and things that render DOM.
I'm very excited (and relieved) to have achieved this milestone.
I had to completely re-architect how this REPL worked 🙈

Today has been great for the Ember Initiative 🐹 And I wanted to share why in a quick 🧵
I'm pretty happy to have @discourse.org as a backer at a tier that allows us to have a 2 hour pairing session every week. We can use this time to work on anything even tangentially related to the Initiative.

You can now use attr() with any CSS property–including custom properties–and it can parse values into data types other than strings.

As of Chrome 131 you have more options to style `

You can now use of the `display` property on these elements, and also use a `::details-content` pseudo-element to style the part that expands and collapses.

Just published a quick writeup of impl work I've been doing lately for Polaris.
TL;DR
- Top-level `renderComponent` API
- Runtime template compiler (for REPLs)
- Component inspector fixes for GJS
- `this.#private` syntax
- hash and array literal syntax

Polaris: What I'm Working On
I've been spending my time doing a lot of long-overdue work on Ember, Glimmer and the Handlebars parser. I figured I'd post a quick list of the work.
