With this 23.10.0 release we are changing the default solver of conda to conda-libmamba-solver! 🥳 🚀​

libmamba builds on libsolv, a much faster solver from openSUSE. The previous "classic" solver is based on pycosat/Picosat and will remain part of conda for the foreseeable future. A fallback is possible and available.

The September 2023 releases included updates to five conda community projects: conda, conda-build, conda-libmamba-solver, conda-index, and pycosat! 🎉 Each of these have been released to both main and conda-forge.

Changes in Conda 23.9.0​

To update conda, run:

conda install -n base conda=23.9.0

📢 Special Announcement 📢​

You can already benefit from conda-libmamba-solver today by configuring your conda installation to use it (e.g. by running conda config --set solver libmamba).

The current "classic" solver is based on pycosat/Picosat and will remain part of conda for the foreseeable future. A fallback is possible and available.

Additional details on this change as well as the full announcement can be found in the conda 23.9.0 changelog.

Welcome to the second issue of the conda Community Newsletter! We're excited to bring you the latest updates and insights, packed with valuable information and exciting developments.

In this issue, we've got a diverse range of topics to cover, including Upcoming Events, new tools like conda-store, thought-provoking discussions on conda's free nature, plugin hooks, and intriguing projects like Pandata. Plus, we'll delve into recent releases that promise to enhance your conda experience.

But that's not all! We'll also highlight one job opportunity and share news about recent talks from Travis Hathaway and Bianca Henderson, now available for public consumption.

Hi All,

A new blog post, titled "Is conda Free?", answers your questions about:

1. what is free to use in the conda ecosystem (most everything),
2. what parts of that ecosystem may not be free, and
3. under what clearly defined circumstances those maybe-not-free parts can still be free after all.

There has been confusion around this since Anaconda introduced its Terms of Service in 2020. I hope the post banishes that confusion (forevermore!). The post is framed as a discussion, introducing why there might be confusion about this topic, and then diving into the details.

Happy reading, and using the conda ecosystem too!

PS: If reading the discussion doesn't grab you then go straight the summary and just pretend you read the whole thing.

PPS: Spoiler alert! ... Yes.

With the latest conda release (23.7.2 at the time this post was written), the ability to define two new plugin hooks was introduced: "pre command" and "post command". These two new plugin hooks give plugin authors the ability to execute code before and after conda commands are run. In this blog post, we provide more details on how and why you may use these to extend the default behavior of conda.

The July 2023 releases are here! 🎊 Conda 23.7.0, 23.7.1, 23.7.2, and conda-build 3.26.0 are now available on both main and conda-forge channels.

Changes in Conda 23.7.0/23.7.1/23.7.2​

To update conda, run:

✨ What's New? ✨​

In the latest release of conda, new pre- and post-command plugin hooks that allow you to run your code before or after a conda subcommand are now available, along with a much improved subcommand plugin hook and plugin infrastructure. There is also a new health check for conda doctor that detects altered packages in an environment by comparing expected and computed sha256 checksums, as well as a much-expanded API and command docs (conda env!).

Welcome to the first ever conda community newsletter! The newsletter will highlight recent and upcoming activity that is relevant to the conda community. This first issue highlights community gathering spaces, upcoming events, the new rattler library, channel updates from conda-forge and Bioconda, a summary or recent conda-related web content, and finally releases and announcements.

We are hoping these will become a semi-regular feature in the conda landscape going forward. If you have an item to include in a future newsletter, please let us know by posting it to the Conda Communications Matrix Channel or by creating an issue in the Conda Communications GitHub Repo.

The newest conda doctor command will be available with conda version 23.5.0, enabling users to quickly detect corrupted packages (packages with files missing) in their conda environment.

One way packages in an environment may become corrupt is when one or more files in that package are accidentally deleted. Even a single missing file leads to a corrupted package. Until now there was no way to learn of these missing files except manually checking for their existence. With conda doctor, users can learn about all such packages in their conda environment with a single short command.

May releases are here! 🎊 Conda 23.5.0, conda-build 3.25.0, and conda-libmamba-solver 23.5.0 are now available on both main and conda-forge:

✨ What's New? ✨​

The long-awaited conda doctor subcommand plugin has been implemented! The related conda issue is over nine years old and has been a regularly requested feature. The conda doctor command enables conda users to detect any packages with files missing (i.e., corrupt packages) in their conda environment.
