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 We will update it to say it is no longer active, and point users to the conda communities on Mastodon and LinkedIn.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.
The November 2023 releases included updates to three conda community projects: conda, conda-build, and conda-libmamba-solver! 🎉 Each of these have been released to both main and conda-forge.
To update conda, run:
conda install -n base conda=23.11.0
New menuinst v2 support!
We recently pushed out a new theme to the documentation sites for conda and conda-build. This theme is also available for all conda related projects to use as a Sphinx theme (check out the conda-sphinx-theme project).

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.
To update conda, run:
conda install -n base conda=23.9.0
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.

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

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.
To update conda, run:
conda install -n base conda=23.7.2
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!).
