## **Flox Release 1.17.0**

## Features

- `flox develop [<package>]` opens a development shell for a Nix expression build, with the package’s build inputs on `PATH` and the stdenv build phases loaded, so a failing build can be driven by hand without a full `flox build`. `-c/--command` runs a command in that shell instead of entering it, and the shell’s build inputs are protected from garbage collection while the shell is open.
- The toplevel `description` manifest field is rendered as Markdown for interactive `flox activate`, and its first line is shown in `flox envs`. Requires `schema-version = "1.17.0"` in `manifest.toml`.
- `flox init -D` creates a `<current_user>/default` environment on FloxHub, equivalent to `flox init -r <current_user>/default`, matching the existing `-D` shorthand on `flox activate`.
- `flox install` includes a description explaining how to activate from shell RC files when it creates a new `default` FloxHub environment for a first-time user.

## Changes

- `flox upgrade --dry-run` no longer builds or downloads packages and only reports which packages have upgrades available. A successful `--dry-run` therefore no longer guarantees that the upgraded environment builds.

## Fixes

- `flox auth status` exits non-zero and prints a warning when your FloxHub token has expired, instead of reporting success with a past expiry date.
- `flox activate --start-services` and the `flox services` commands recover automatically when a previous service manager was killed without cleaning up its socket. Previously the environment’s services stayed unusable until the socket file was deleted by hand.
- `flox` prompts only once for access to the keychain instead of every release.
- Catalog requests wait for the server-requested delay and retry when the service is temporarily unavailable.
- `flox config -l` documents why it omits unset optional configuration values, including `auto_activate`.
