Release: Flox 1.3.17

Flox Team | 1 April 2025
Release: Flox 1.3.17

We’ve just released version 1.3.17 of the Flox CLI. You can get the new release here.

Notable features and fixes

This release addresses several bugs and adds new improvements, including:

  • Activation mode can now be specified in the manifest, is supported by flox activate and flox containerize, and is set when creating a "default" environment.

    Previously the only way to specify an activation mode was to use a --mode flag with run or dev as options. As a reminder, run will only put top-level package executables in your $PATH whereas dev will add libraries and executables from dependencies to your environment as well.

    For example, an environment with the almonds package activated in run mode will allow you to run almonds. The same environment activated in dev mode will also give you access to the version of Python that almonds depends upon along with all of its required modules.

See the Flox manifest documentation for more information

Node ecosystem improvements

  • Node ecosystem: flox init automatic setup should now work for projects that depend on yarn versions greater than 1.
  • Users should no longer see a message about an internal search operation during automatic setup of Node environments

Containerize

  • /tmp now exists in containers built via flox containerize

Thank you to our community contributions this release

  • @RichardAlmanza fixed a bug where editing an environment would fail when using certain versions of Nix to run Flox
