Conda is moving our social media presence from Twitter/X to Mastodon and LinkedIn at the start of 2024. It's past time to move into spaces that are welcoming and more in line with our community values.

Going forward, you can find us at

If you are on either platform then please follow and link to those accounts, or, just use the #conda hashtag.

We won't close the Twitter account. We will update it to say it is no longer active, and point users to the conda communities on Mastodon and LinkedIn. If you are active on Twitter, we encourage you to also use the #conda hashtag.

We hope to see you on Mastodon and LinkedIn in 2024!

PS: conda-forge is discussing making the same move.

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 📢​

info

Conda's default solver will change to conda-libmamba-solver in a special 23.10.0 release in the near future!

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.

Is conda free?

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!
Dave C

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.
