The key option is:
```
"configurations": [

We recently celebrated 10 years of @condaforge on our Zulip. I'd love to hear your story if you are involved with conda-forge. The project has grown to over 30'000 packages, and still grows at a crazy rate.

lysnikolaou of @quansight.com (Lysandros Nikolaou), all of the mandatory dependencies of #aiohttp now ship free-threaded variants of #wheels!
This unlocks the same in aiohttp!

Table of dependencies for Python, with linked package names, and version and build columns.
This is how it looks for `conda-forge::python`:

I've added a couple features to conda-metadata-app.streamlit.app.
1️⃣ If you check "Show dependencies as rich table" you'll get hyperlinked package names with separate columns for version and build strings.
2️⃣ The "Download artifact" link now reports the total size of the package.
It's here at last! 🎉 We're excited to present Quansight Labs' 2024 Annual Report, showcasing our advancements, community involvement, and commitment to sustainability in open source. We're eager for a bright future ahead. 🔮 Read the full report: buff.ly/NfQ0hUx

In the screenshot above, "PR" is a text field with value:
<a href="https://github.com/conda/conda/pull/13928">PR</a>
TIL you can add <a href="...">URLs</a> to Github Projects text fields and they will be rendered in the item tab nicely!
I'm using this to link to items without an associated issue, without having to click on the item description. Pretty neat!
(Sadly you can't use <img src="..." />)
The secret sauce is in step 2 👀

It was a long journey from coming up with a new, community approved spec to the first v1 recipe on conda-forge 🎉 – more details in the blog post.
We're excited to introduce R-Lite, a #WebAssembly distribution of #R for the browser, allowing you to use the R kernel in JupyterLite!

It doesn't have one because it would allow you to change platforms in an existing environment, which is often not wanted. Isn't osx-64 automatically chosen for you? It should remember.

Remember when a bunch of folks freaked out when Github added underlines to all their hyperlinks? Nope, I hadn't thought about that a single second til today. Everyone's happier now, and no one lost a single eyeball with this change.
