Note: This release includes changes to how package outputs are handled that may trigger automatic manifest migrations. Migrated manifests will require CLI version 1.10.0 or above. See the Changes section below for details.

Compatibility policy:

Starting with this release, the Flox CLI is schema-aware. It detects when modifications to an environment are backwards compatible, and automatically migrates manifests when changes aren’t backwards compatible. The version field has been replaced with a schema-version field. See the compatibility policy docs for details.

Features:

  • Package outputs are now supported, allowing you to specify which package outputs to include in your environment using flox install curl^bin or by setting outputs in the manifest.
  • flox install and flox search now show hints when a package has additional package outputs available.
  • The “building from source” spinner now explains why a package is being built from source (e.g. marked as unfree or has no upstream build available).

Changes:

  • Package installations now include only the default package outputs defined by the upstream Nix package. Previously, all package outputs were installed. Existing environments that relied on non-default package outputs will be automatically migrated to set outputs = "all" for those packages in the manifest, preserving existing behavior. Note that migrated manifests will require CLI version 1.10.0 or above.

Fixes:

  • flox edit --sync and flox edit --reset now work for FloxHub environments, previously failing with “Cannot sync local or remote environments.”
  • flox activate -m dev no longer incorrectly adds coreutils binaries to the path, fixing a regression from v1.9.0.
  • Bash completion now works for flox activate positional arguments, and flox activate -c no longer produces an eval error when tab-completing inside quotes.
  • Removed several unused internal FLOX_* environment variables from flox activate.
