# Changelog

> What's new across the Flox CLI, FloxHub, and extensions

New releases, improvements, and fixes across Flox, in reverse-chronological
order. Subscribe to the [RSS feed](/changelog/rss.xml) to follow along.

<Update label="July 29, 2026" description="v1.14.0" tags={["Flox CLI"]}>
  ## Auto-activation

  Flox now prompts to auto-activate environments when your shell enters
  their directory, and deactivates them on the way out — packages,
  environment variables, shell aliases, and services all load with a single
  `cd`. See the
  [auto-activation docs](/concepts/auto-activation).

  ## FloxHub personal access tokens

  `flox auth login` accepts personal access tokens generated on your FloxHub
  profile page, supports non-interactive login via `--token-file`, and now
  stores credentials in your OS keychain instead of plain text — existing
  tokens migrate automatically.

  ## Also in this release

  * Trust every environment from an organization at once with
    `flox config --set 'trusted_environments.myorg/*' trust`.
  * Packages that ship `etc/profile.d` scripts have them sourced on
    activation.
  * `flox build update-catalogs` is deprecated — catalog inputs for Nix
    expression builds now resolve and lock automatically during `flox build`
    and `flox publish`.

  See the [v1.14.0 release notes](https://github.com/flox/flox/releases/tag/v1.14.0).

<Update label="July 27, 2026" description="v1.0.0" tags={["Flox skills"]}>
  ## Flox skills v1.0.0

  Expert Flox guidance for your AI coding agent: the `flox` skill creates
  and manages reproducible environments, and `floxify` onboards an existing
  repo — it detects runtimes, package managers, and services, then writes
  the manifest so `flox activate` is the only setup a new developer needs.
  Works with Claude Code, Codex, and any agent supporting the
  [skills.sh](https://skills.sh) standard. See the
  [v1.0.0 release notes](https://github.com/flox/flox-skills/releases/tag/v1.0.0).
</Update>

<Update label="July 14, 2026" description="v1.13.2" tags={["Flox CLI"]}>
  ## Auto-activate improvements

  Declining the auto-activation prompt is now remembered, re-allowed
  environments return to their correct position in the activation stack,
  and the prompt no longer hangs on fish. (Experimental — enable with
  `flox config --set features.auto_activate true`.)

  ## Custom catalogs in `flox run`

  `flox run -p owner/pkg -- ...` now runs packages from custom catalogs
  using an authenticated download path.

  See the [v1.13.2 release notes](https://github.com/flox/flox/releases/tag/v1.13.2)
  for the full list of fixes.
</Update>

<Update label="June 30, 2026" description="v1.13.1" tags={["Flox CLI"]}>
  ## Run packages without an environment

  `flox run -p <package> -- <command>` resolves, downloads, and executes a
  Flox Catalog package in a single step — no environment required. Packages
  not in the binary cache, such as unfree packages, build from source
  automatically.

  ## Containerize dev or run directly

  `flox containerize` accepts `--mode` to containerize the `dev` or `run`
  environment without editing the manifest, and
  `flox build import-nixpkgs` gains `--stability` to select the nixpkgs
  revision used for the import.

  See the [v1.13.1 release notes](https://github.com/flox/flox/releases/tag/v1.13.1).
</Update>

<Update label="June 17, 2026" description="v1.13.0" tags={["Flox CLI"]}>
  ## `flox deactivate`

  Leave an active environment and return your shell to its previous state
  without closing it, plus a new `profile.deactivate` section for scripts
  that run on the way out.

  ## Build sandbox levels

  Manifest builds add `warn` and `enforce` sandbox levels alongside `off`
  and `pure`, with a `sandbox-allow` list for files outside the build
  closure.

  ## Faster, clearer environment operations

  `flox upgrade` output now separates version changes from same-version
  rebuilds, `flox activate` skips re-locking environments that are already
  current, and environment creation uses one `nix build` invocation per
  build-and-link cycle instead of three.

  See the [v1.13.0 release notes](https://github.com/flox/flox/releases/tag/v1.13.0).
</Update>

<Update label="June 2, 2026" description="v1.12.2" tags={["Flox CLI"]}>
  ## Flox CLI v1.12.2

  Manifest builds can now use `git describe` to set version strings,
  `flox publish` no longer triggers unnecessary rebuilds, and debug output
  gains color highlighting to make slow operations easier to spot.
  See the [v1.12.2 release notes](https://github.com/flox/flox/releases/tag/v1.12.2).
</Update>

<Update label="May 19, 2026" description="v1.12.1" tags={["Flox CLI"]}>
  ## Default environment shortcut

  The `-D`/`--default` flag references your default FloxHub environment in
  any command that accepts `-r`/`--reference`, replacing `-r <user>/default`.

  ## Smarter install and publish

  `flox install <package>^<output>` now appends outputs to packages that
  are already installed, and `flox publish` skips the rebuild and publish
  when the exact build has already been published.

  See the [v1.12.1 release notes](https://github.com/flox/flox/releases/tag/v1.12.1).
</Update>
