Release: Flox 1.3.8

Flox Team | 13 December 2024

This is a maintenance release that fixes a bug introduced in v1.3.7.

This bug occurs only if all of the following conditions are met:

You're on macOS;
Your shell is zsh;
You have defined a default Flox environment;
You have added the line eval "$(flox activate -d ~ -m run)" to .zshenv;

This issue stems from the way macOS handles PATH initialization. Specifically, the macOS path_helper utility, which is responsible for adding /usr/local/bin to PATH and therefore making the flox executable available in PATH, runs after .zshenv is sourced.

Our test suite didn't catch this bug because it uses absolute paths and therefore doesn’t rely on PATH. We will add regression tests to catch this particular bug, and will be augmenting the test suite to catch other bugs like this in the future.

Note: If you aren’t using MacOS, there is no material difference between Flox versions 1.3.7 and 1.3.8.
