# Changelog

All notable changes to this project are documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [0.3.1] - 2026-10-03

### Changed

- Requires Mutare 0.5 (`{:mutare, "~> 0.5.0"}`) and `mutare_plug` 0.2.1.

## [0.3.0] - 2026-09-26

### Changed

- **Breaking: requires Mutare 0.4.1 and mutare_plug 0.2** (`{:mutare, "~> 0.4.1"}`,
  `{:mutare_plug, "~> 0.2"}`). Mutare 0.4.0 offers a call written as a pipe stage to a
  mutator as the direct call it is sugar for, with the piped value as its first argument;
  the families here read their argument positions that way now and no longer need Mutare's
  removed pipe-mode API.
- A mutant that leaves the piped value alone is still reported at the stage
  (`conn |> json(%{id: 1})` → `json(%{})` at the `json` stage, as before); one that
  replaces the whole call is reported over the whole pipe.

### Added

- The removal families mutate a call written as a pipe stage. `socket |> push("ack", %{})`
  and `pubsub |> Phoenix.PubSub.subscribe(topic)` now collapse to `:ok` over the whole pipe,
  upstream stages included; through 0.2.0 the piped spelling was left alone because the
  `:ok` could not be spelled as a stage.

## [0.2.0] - 2026-09-14

### Added

- `Mutare.Phoenix.ChannelReply` (`:channel_reply`) — drops replies from
  channel return tuples in modules implementing `Phoenix.Channel`, exposing
  tests that do not check join payloads or callback replies.
- `Mutare.Phoenix.ChannelMessage` (`:channel_message`) — replaces channel
  broadcast, push, and deferred reply calls with `:ok`, exposing tests that
  do not assert outbound messages.
- `Mutare.Phoenix.PubSub` (`:pubsub`) — replaces subscription, unsubscription,
  and broadcast calls with `:ok`, exposing tests that do not check message
  delivery or subscription changes.
- `Mutare.Phoenix.Token` (`:token`) — swaps `sign` ↔ `encrypt` and
  `verify` ↔ `decrypt`, replaces token payloads with `nil`, and disables
  expiry by replacing explicit integer `max_age:` values with `:infinity`.
  Marks `max_age:` as a timeout so built-in integer and atom mutators skip it.
- Variant-specific ignore support for channel message, PubSub, and token
  mutations, such as `# mutare:ignore[token:expiry]`.

### Changed

- `Mutare.Phoenix.all/0` now includes the four new families alongside the
  three controller families, enabling them in configurations using this preset.

## [0.1.0] - 2026-09-07

Initial release. Builds on `mutare_plug`, which provides the `Plug.Conn`
families (`:plug_halt`, `:http_status`, `:plug_session`, `:resp_header`,
`:resp_cookie`, `:resp_body`).

### Added

- `Mutare.Phoenix.Redirect` (`:redirect_status`) — swaps explicit atom
  `status:` options on `Phoenix.Controller.redirect/2` among valid redirect
  status siblings.
- `Mutare.Phoenix.Body` (`:controller_body`) — blanks the body argument of
  `Phoenix.Controller.json/2` to `%{}` and of `text/2` / `html/2` to `""`
  ("does any test read the rendered body?"); on a literal text/html body its
  whole-call rewrite supersedes the built-in string family's sentinel leaves
  via Mutare's overlap pruning.
- `Mutare.Phoenix.Download` (`:download_disposition`) — flips the explicit
  `disposition:` option of `Phoenix.Controller.send_download/3` between
  `:attachment` and `:inline`.
- `Mutare.Phoenix` as a `Mutare.CallRouting` extension (list it under
  `:extensions`): routes the `Phoenix.Router` DSL (`get`/`scope`/…) `:skip`,
  so compile-time route definitions are left unmutated, and
  `Phoenix.Component.sigil_H/2` (`~H`) arguments as compile-time literals, so
  HEEx arguments remain valid during metamutant compilation.
- `Mutare.Phoenix.all/0` for splicing the Phoenix families into a `:mutators`
  list, composing with `Mutare.Plug.all/0`.
