Release: Flox 1.3.17
Flox Team | 1 April 2025

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
andflox containerize
, and is set when creating a "default" environment.Previously the only way to specify an activation mode was to use a
--mode
flag withrun
ordev
as options. As a reminder,run
will only put top-level package executables in your$PATH
whereasdev
will add libraries and executables from dependencies to your environment as well.For example, an environment with the
almonds
package activated inrun
mode will allow you to runalmonds
. The same environment activated indev
mode will also give you access to the version of Python thatalmonds
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 viaflox containerize
