## **Flox Release 1.19.0**

## Warning

- ⚠ Starting October 20, 2026, you need to be logged in to a free FloxHub account to install packages, upgrade them, or do anything else that resolves packages from the Flox Catalog. We timed the change to land with this release, but the Flox Catalog enforces it, so it applies to every Flox version and not just 1.19.0. Run `flox auth login`, or set `FLOX_FLOXHUB_TOKEN` in CI. Searching for packages and activating an environment whose lockfile is up to date stay public. Logging in works on Flox 1.3.5 and newer, and tokens need 1.14.0 or newer. Details: [Authentication - Flox](https://go.flox.dev/auth)

## Features

- Package groups can resolve against a specific catalog stability, set per group with `pkg-groups.<NAME>.stability` or for all groups with `options.stability`. This introduces manifest schema version 1.19.0.
- `flox list --all` shows an environment-detail block with generation and sync information, per-package upgrade availability and stability, an available-upgrades summary, and next-step hints, all without making network requests.
- `flox build`, `flox publish` and `flox develop` list the available packages when the named package doesn’t exist, and `flox publish` and `flox develop` prompt for a package when there are several and none is named, or list them when not running interactively.
- `flox activate` and `flox run` prompt you to run `flox auth login`, or to log in again when a login has expired, if downloading a custom-catalog package requires FloxHub authentication, instead of reporting that the package may have been deleted.
- `flox search` and `flox services status` align their tabular output more consistently.

## Fixes

- `flox run` asks you to log in before showing the package picker, rather than after you’ve made a choice, when several packages provide the command and you are not logged in.
- `flox install`, `uninstall`, `edit` and `upgrade` work in Docker and podman when the environment came from an earlier image layer.

## Thank you to our community contributions this release

- Concurrent activations of the same environment no longer fail because of a race on the activation lock file (@fzakaria)
