    * The speedy `conda-libmamba-solver` as its default dependency solver.  This and other improvements make `conda` run 4-5x faster.
    * Support for plugins, enabling you to customize your conda installation.
    * Package builders can now include desktop icons across all operating systems, which is especially useful for GUI applications.
    * The [conda documentation](https://docs.conda.io/en/latest/) has been refresshed and updated.
* [**`pixi`**](https://pixi.sh/) a new open-source conda-compatible package and environment manager led by the folks at prefix.dev. Implemented in Rust, using the recently intoruduced Rattler library as a foundation.  See [the announcement](https://prefix.dev/blog/launching_pixi) for details.
* **`conda-build`** now supports `emscripten-wasm32` and `wasi-wasm32` platforms.
* **`conda-lock`**, **`mamba`**, **`rattler-build`**, **`grayskull`**, **`quetz`**, **`rattler`**, **`condax`** and many other projects had new releases too.

**Newly welcomed projects**

These projects joined the [conda-incubator](https://github.com/conda-incubator):
* [`conda-store`](https://github.com/conda-incubator/conda-auth) and kin support storing, reusing, and sharing conda environments.   
* The [`conda-auth` plugin](https://github.com/conda-incubator/conda-auth) supports authenticated access to private channels in `conda`. (The [plugins repo](https://github.com/conda-incubator/plugins) lists this and other available plugins.)

Conda is one of thirteen projects selected to participate in the [2023 Google Season of Docs](https://developers.google.com/season-of-docs/docs/participants). We are looking for a contributor to [help make the upcoming conda.org community web site the goto place for the conda community](https://github.com/conda-incubator/conda-dot-org/discussions/73).
