 	* Change the default pymsrc URL. [PR #45](https://github.com/INN/pym-shortcode/pull/45) for [issue #8](https://github.com/INN/pym-shortcode/issues/8).
 	* Override block and shortcode pymsrc URLs with the default pymsrc URL. [PR #45](https://github.com/INN/pym-shortcode/pull/45) for [issue #8](https://github.com/INN/pym-shortcode/issues/8).
 * Adds an informational page, available to all who can make posts, that lists the plugin's default source URL for `Pym.js`. This is to make the process of building new interactives easier.
-* Shortcode now gains an `align=""` parameter, so that WordPress's generated [alignment CSS classes](https://codex.wordpress.org/CSS#WordPress_Generated_Classes) can be used on embeds. By enabling this in the shortcode, the Gutenberg Block also gains support for alignment. [PR #34](https://github.com/INN/pym-shortcode/pull/34)
+* Shortcode now gains an explicit `align=""` parameter, so that WordPress's generated [alignment CSS classes](https://codex.wordpress.org/CSS#WordPress_Generated_Classes) can be used on embeds. By enabling this in the shortcode, the Gutenberg Block also gains support for alignment. [PR #34](https://github.com/INN/pym-shortcode/pull/34). Prior to this release, the alignment classes could be added via the `class=""` parameter.
 * Script tags for embeds are no longer output by `the_content()`, instead being output during `wp_footer()` by [closures](https://secure.php.net/manual/en/functions.anonymous.php) hooked on the `'wp_footer'` action. [PR #34](https://github.com/INN/pym-shortcode/pull/34) for issues [#33](https://github.com/INN/pym-shortcode/issues/33) and [#35](https://github.com/INN/pym-shortcode/issues/35).
 * The script tag used to run `new pym.Parent` is now configurable. By replacing the [pluggable function](https://codex.wordpress.org/Pluggable_Functions) `pym_shortcode_script_footer_enqueue()` with your own function, you can now use alternate forms of embed code that may be required for PJAX sites or custom versions of Pym.js. This resolves issue [#19](https://github.com/INN/pym-shortcode/issues/19).
 * Adds "Requires PHP: 5.3" metadata to the plugin's `readme.txt`, since we're now using PHP namespaces for some code.
