It’s a big release day today, with both the next release of sunpy core and the long awaited (over two years in development) release of ndcube 2.0.

Read all about it here: [October Release Announcements — sunpy.org](https://sunpy.org/posts/2021/2021-10-29_sunpy_31_ndcube_20)

Both packages are on conda and PyPI so you can install them with:

```auto
pip install -U sunpy[all]
pip install -U ndcube[all]

```

or

```auto
conda install -c conda-forge sunpy
conda install -c conda-forge ndcube

```

Happy Friday 🥳

Hi, nice to see you are using Discourse.

I am confused with the installation. Just installed Sunpy on a Windows machine with conda. I did `conda install -c conda-forge sunpy` but when doing a `sunpy.map.whatever` I got the error that sunpy has no attribute `map`. Then I see on the installation info that for a pip installation, we do need to explicitly include dependencies, as you show above with `all`. Is that needed with conda too? If not, any idea why i’m missing the `map` attribute after a conda install?

Have you done `import sunpy.map`? the `.map` submodule isn’t imported into the top namespace.

There are no optional dependencies with conda (other than asdf).

(also I just realised that this is an annoucements only thread, please start a new one as this one notifies a bunch of places!)
