  * Allow string fields on `input_changed?`

## v3.3.2 (2023-08-10)

* Enhancements
  * Address deprecations in Elixir v1.16+

* Deprecations
  * Deprecate `inputs_for/2` and `inputs_for/3` (without anonymous functions)

## v3.3.1 (2023-02-27)

* Bug fix
  * Set display to none on generated forms
  * Warn for maps with atom keys

## v3.3.0 (2023-02-10)

* Enhancements
  * Support deeply nested class lists
  * Implement Phoenix.HTML.Safe for URI
  * Implement Phoenix.HTML.FormData for Map

* Bug fix
  * Generate unique IDs for checkboxes based on the value
  * Use artificial button click instead of `form.submit` in JavaScript to trigger all relevant events
  * Fix a bug where nil/false/true attributes in `aria`/`data`/`phx` would emit empty or literal values, such as `"true"` and `"false"`. This release aligns them with all other attributes so both `nil` and `false` emit nothing. `true` emits the attribute with no value.

* Deprecations

## v3.2.0 (2021-12-18)

* Enhancements
  * Raise if the `id` attribute is set to a number. This is actually an invalid value according to the HTML spec and it can lead to problematic client behaviour, especially in LiveView and other client frameworks.

  * Allow hidden fields in forms to be a list of values

## v3.1.0 (2021-10-23)
