AI Share & Summarize — 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 ==".

= 2.0.1 =
* Fix: Visitor-facing "Generate AI summary" click made the summary box look empty until the page was reloaded — the placeholder element was being replaced by the inline critical CSS `<style>` block instead of the actual `<aside>` summary. The replacement now targets the `<aside>` element explicitly.

= 2.0.0 =
* New: Inline AI summary feature — the plugin's namesake "Summarize" capability now generates a short summary of each post and shows it inline in a collapsible block alongside the share buttons
* New: Two-tier provider cascade — Level A uses the WordPress 7.0 AI Client (`wp_ai_client_prompt()`) with credentials managed centrally in Settings > Connectors (OpenAI, Anthropic, Google), so no API keys are configured in this plugin
* New: Level C PHP extractive fallback for sites on WP < 7.0 or without an AI Connector — picks the most representative sentences using token-frequency scoring with a Jaccard-similarity filter to avoid redundant sentences
* New: Dedicated "AI Summary" settings section with independent post-type selection, position, default collapsed state, sentence count (also used by the AI prompt), extractive fallback opt-out and per-feature controls
* New: Block editor sidebar panel to view the current summary, edit it manually (which locks it against auto-regeneration) and trigger a synchronous regeneration on demand
* New: Classic editor meta box equivalent — view, edit and force regeneration on next save, with admin notice showing the result or the underlying AI error
* New: Visitor-facing "Generate AI summary" button for posts without a stored summary, with admin setting to keep generation extractive-only (zero cost) or allow the AI Client (rate-limited to 1 generation per IP per minute)
* New: `[ayudawp_aiss_summary]` shortcode to render the summary outside the auto-insert flow (accepts a `post_id` attribute)
* New: REST endpoints `POST /aiss/v1/summary/regenerate` (capability `edit_post`) and `POST /aiss/v1/summary/generate` (public, rate-limited)
* New: Schema.org microdata on the summary block (`CreativeWork` + `abstract`) plus `data-nosnippet` so search engines understand it's a derived summary and don't compete it as a featured snippet against the original content
* New: Last AI Client error is persisted and surfaced in the settings page, so configuration issues are visible without enabling `WP_DEBUG`
* New: `aiss_summary` icon in `AyudaWP_AISS_Icons` for the collapsible block header
* New: Filter `ayudawp_aiss_extractive_stopwords` to extend the extractive summarizer with additional languages (ships with English and Spanish)
* New: Filter `ayudawp_aiss_extractive_weights` to tune lead bonus, title-word weight, minimum sentence length and similarity threshold of the extractive summarizer
* New: Async generation via WP-Cron (`wp_schedule_single_event`) so the editor save never blocks waiting for the AI provider; explicit user actions (sidebar "Regenerate now", classic-editor "Regenerate on next save") run synchronously for immediate feedback
* Improved: Frontend "Generate AI summary" button rewritten in vanilla JS (outside the jQuery ready cycle) so it survives aggressive defer/async optimizations from caching and performance plugins
* Improved: Critical inline CSS is now printed alongside the summary HTML so the collapsible block stays visually correct even when the main stylesheet is deferred with `rel="preload"`
* Improved: Shortcodes (`[gallery]`, `[caption]`, plugin-defined ones, etc.) are now stripped from post content before summarization so the resulting summary no longer includes raw shortcode markup
* Improved: Minimum WordPress version raised to 5.6 to use `wp_after_insert_post`, which fires after meta updates and avoids redundant regenerations

= 1.9.2 =
* Fixed: Share buttons not appearing with Divi Theme Builder (Divi 4 and Divi 5), FSE block templates and Bricks Builder — these render the post content through the `the_content` filter without a standard WP loop, so the previous `in_the_loop()` and `is_main_query()` guards blocked the auto-insertion. The singular-page path now relies on `is_singular()` plus a post-ID match between `get_the_ID()` and `get_queried_object_id()`, with a per-request "already processed" guard so the same post can never receive duplicate button blocks. Archives keep the original main-loop check

= 1.9.1 =
* Fixed: Empty space below the footer on themes that don't clip body overflow — universal tooltips were created at the end of `<body>` with no initial coordinates, extending the document scroll height by their static size

= 1.9.0 =
* Added: Optional "Dark mode adaptation" setting (Disabled by default / Auto). When set to Auto, a tiny script measures the real background luminance of the buttons container and only adapts colors when it is genuinely dark — so light pages stay untouched even if the visitor's OS prefers dark
* Added: Light border on X, Threads and Grok buttons over dark backgrounds so they stand out from the page (Auto mode)
* Added: Section and global titles now also display when using the "Icons only" button style
* Improved: Outline style shows X, Threads and Grok in white over dark backgrounds (instead of unreadable black) — Auto mode
* Improved: Minimal style text and titles use legible light colors on dark backgrounds — Auto mode
* Changed: Version history moved to a dedicated changelog.txt file served from the plugin's public SVN, keeping readme.txt focused on the current release

= 1.8.0 =

* Added: NoIndexer and Periscope plugins to the promotional banner rotation
* Improved: SEO integration settings now display all detected noindex providers

= 1.7.4 =
* Fixed: Block editor sidebar panel translations now load correctly via wp_localize_script() instead of relying on JSON translation files

= 1.7.3 =
* Improved: Block editor now uses a native sidebar panel (PluginDocumentSettingPanel) instead of a classic meta box for the post exclusion checkbox
* Improved: Compatible with WordPress 7.0 real-time collaboration (RTC) — the classic meta box no longer disables collaborative editing
* Improved: Sidebar panel includes plugin dashicon for better visual identification
* Improved: Fallback to classic meta box in the block editor if the sidebar script is missing

= 1.7.2 =
* Fixed: Buttons appearing in footer or sidebar on themes that apply the_content filter outside the main loop
