Scheduled Posts Showcase — Full changelog

For each release, see the entries below. The latest version is always at the top.
The current release notes also live in readme.txt under "== Changelog ==".

= 1.2.0 =
* New: heading tag options for paragraph, span and div in addition to H2-H6.
* New: "Custom CSS class" field on the settings page. Adds extra classes to every instance container (widget, block, shortcode).
* New: "Extra CSS class" field on the widget, the block inspector and as `custom_class` shortcode attribute. Per-instance classes are appended to the global ones, never replace them.
* New: "Full width (responsive)" image size that stretches the thumbnail to the container width, useful for sidebar hero-style cards.
* New: `spscase_heading_tags` and `spscase_image_sizes` filters to extend those lists from code.
* Improved: settings page moved to Appearance > Future Posts instead of Tools, since the plugin is mostly about visual display. The page slug is unchanged so existing bookmarks pointing to `?page=scheduled-posts-showcase` still work.
* Improved: image size selector now lists every size registered on the site (themes and plugins included) instead of just thumbnail and medium.
* Improved: clearer help text on the CSS class fields. They add the class name to the container; the CSS itself still has to live in your theme or in Customize > Additional CSS.
* Improved: promo catalog on the settings sidebar updated with the latest AyudaWP plugins, including the rest of the Native SEO Suite, and small visual fixes aligned with the AyudaWP banner guide.
* Fix: the block preview no longer fails in the block-based widgets editor. The editor script now declares `wp-server-side-render` as an explicit dependency via a companion `.asset.php` file, which the widgets editor was not pulling in transitively (resulting in a React #130 error).

= 1.1.0 =
* Improved: block registration migrated to block.json metadata for full compatibility with the iframed block editor in WordPress 6.9 and 7.0.
* Improved: block API version upgraded from 2 to 3.

= 1.0.1 =
* Improved: tested up to WordPress 7.0.

= 1.0.0 =
* New: initial release with shortcode, classic widget, Gutenberg block (with ServerSideRender preview) and public REST API endpoint.
* New: global settings page with cascade model so each instance can override the defaults.
* New: visibility control for who can see scheduled posts (everyone, logged-in users only, editors and administrators).
* New: transient caching with automatic invalidation when a post is scheduled, published or deleted.
* New: extensive hook system (filters and actions) for developers to customize query args, post data, output HTML, REST response, date format, excerpt length, cache duration and allowed footer HTML.
