Super Duper SEO Title and Description

變更記錄

1.8.1 – 20.05.2026

• Tested with WordPress 7.0.
• No functional changes — pure compatibility bump.

1.8.0 – 19.05.2026

Extended PHP compatibility — minimum PHP version lowered to 8.0.
* Changed: Minimum PHP requirement lowered from 8.2 to 8.0. The plugin now runs on PHP 8.0, 8.1, 8.2, 8.3 and 8.4.
* Verified: Codebase audited for PHP 8.1+/8.2+ specific syntax (readonly properties/classes, enums, never return type, first-class callable syntax, intersection types, DNF types, new in initializers, standalone true/false/null return types). None present.
* Verified: No PHP 8.1+/8.2+ only standard library functions used (array_is_list(), enum_exists(), Random\Randomizer, mysqli_execute_query(), etc.).
* No functional changes — this is a pure compatibility release. Existing installations on PHP 8.2+ are unaffected.

1.7.2 – 16.05.2026

• Fixed: Plugin Check compliance — escape $badge output in the LLMs.txt status column on post lists via wp_kses_post().
• Fixed: Plugin Check compliance — translators: comments aligned directly above __() calls inside nested wp_kses() / printf() constructs (LLMs.txt setup tab, meta box section description, meta box disabled-output notice).
• Fixed: Plugin Check compliance — $_REQUEST['sdstd_llms_bulk_include'] now goes through wp_unslash() and sanitize_text_field() before being checked in the bulk-edit handler.
• Fixed: Plugin Check compliance — backticks added around dynamic table identifiers in all custom-table SQL queries (redirects core, redirects admin) and phpcs:disable/enable blocks correctly bracket the query lines.
• Fixed: Plugin Check compliance — sanitization annotations clarified for the nested $_POST['sdstd_blocks'] payload, which is sanitized field-by-field inside SDSTD_LLMs_Blocks::sanitize().
• Improved: meta_query calls in the Setup tab dashboard and llms.txt generator carry a clear comment explaining why they are acceptable here (cached output, dashboard-only).
• Improved: Nonce-verification PHPCS annotations in the admin notice extended to cover all $_GET references in the read-only page detection block.
• Improved: Upgrade notices for 1.7.0 and 1.7.1 trimmed below the 300-character limit required by WordPress.org.
• No functional changes — this is a pure code-quality and review-compliance release.

1.7.1 – 16.05.2026

• Fixed: The Short Answer block in the Setup tab and the llms.txt Summary field under Settings → Indexing & AI Crawlers could drift apart, producing inconsistent output between the blockquote at the top of llms.txt and the Short Answer section further down.
• Fixed: Saving the Setup tab now automatically mirrors the Short Answer block (Headline + Body) into the llms.txt Summary field, so the file output stays consistent with what is shown in the Setup tab.
• Improved: The llms.txt Summary field under Settings → Indexing & AI Crawlers is now displayed as read-only with an info banner pointing users to the Setup tab as the single source of truth.
• Improved: DAU-friendly rewrite of the Setup tab — every block now includes three real-world examples (service business, online shop, local business) with realistic Swiss SME numbers, addresses and prices. Block descriptions use plain language without jargon.
• Improved: All 13 locale translations regenerated to match the refreshed UI strings.

1.7.0 – 16.05.2026

Major llms.txt upgrade — full rewrite following the official llmstxt.org specification, plus a dedicated AI-friendly Setup tab with global content blocks.

llms.txt output:
* New: Complete rewrite of /llms.txt and /llms-full.txt following the official llmstxt.org specification – curated H1, blockquote summary, configurable H2 sections and [Title](URL): Description bullet format.
* New: /llms-full.txt now contains the FULL Markdown-converted body of every included page (not 50-word excerpts) – HTML is properly converted to Markdown, shortcodes are processed, scripts/styles/iframes/navigation are stripped, entries are separated by ---.
* New: Strict curation – only pages with a non-empty LLM Description are listed in llms.txt. This stops cart, checkout and stub pages from diluting the signal.
* New: Spec-compliant footer block with Language:, Canonical: and Generator: metadata lines.
* Fixed: llms.txt and llms-full.txt are no longer near-identical files – they now serve their distinct purposes (curated index vs. full content corpus).

Global semantic blocks (new Setup tab):
* New: Six site-wide content blocks for llms.txt that AI search engines (Perplexity, ChatGPT Search, Google AI Overviews) read as authoritative context: Short Answer, Product / Main Offering, Pricing, Target Audience, Money Keyword, Company Information.
* New: llms.txt Setup tab under SEO & Title → Settings → llms.txt Setup — a single dedicated screen with all six blocks, structured repeater rows for features/pricing/audiences, live-rendered Markdown preview per block, and one Save button.
* New: Beginner-friendly examples — every block has an expandable “See how other businesses fill this in” panel with three concrete examples (service business, online shop, local business) including realistic Swiss SME numbers, addresses and prices.
* New: Status dashboard at the top of the Setup tab showing three live metrics: llms.txt output state, global blocks completeness (X of 6 with progress bar), curated pages count (X of Y with progress bar).
* New: Automatic seed migration — on upgrade, the Short Answer headline is seeded from the WordPress site title, the body from the existing llms.txt summary or tagline, and the Company block from site title, admin email and home URL. Existing user content is never overwritten.
* New: All six blocks render in spec-compliant Markdown between the curated sections and the “Optional” section in llms.txt — empty blocks are omitted entirely, no empty H2 headings.

Per-post controls:
* New: Dedicated “LLMs.txt” tab in the SEO meta box with four per-post fields:
* LLM Description (1–2 sentences of real context for AI systems, NOT the SEO description)
* Section (where the page appears in llms.txt)
* Priority (Top or Normal — top pages list first inside their section)
* Include in llms.txt (checkbox to exclude a page completely)
* New: Post editor shortcuts — two new buttons above the LLM Description textarea: “From Excerpt” copies the post’s excerpt as starting value; “From SEO Description” copies the SEO meta description. Both only appear when the source has content. Existing values are protected by a confirmation dialog.
* New: Status column on the post/page/product list – 🟢 curated, 🟡 link only, ⚪ excluded. With ⭐ marker for Top-priority pages and the section label as a small caption.
* New: Quick Edit and Bulk Edit support for LLM Description, Section, Priority, and Include fields directly from the post list.

Configuration & defaults:
* New: Configurable sections under Settings → Indexing & AI Crawlers. Defaults: Services & Offerings, Pricing & ROI, Insights & Guides, Optional. Add/remove/reorder sections freely; the “Optional” section is always rendered last per spec.
* New: Multi-line llms.txt Summary field (2–3 sentences positioning / target audience / USP) replaces the single-line introduction. Legacy sdstd_llms_txt_intro value is migrated automatically.
* New: Auto-Exclude Slugs setting – cart, checkout, my-account, lost-password, order-received, thank-you, login etc. are excluded by default; the list is editable.
* New: WooCommerce products are now excluded from llms.txt by default (configurable). Even when enabled, products require a curated LLM Description to be listed.
* New: Clear UI hint on the LLMs tab and Settings page – llms.txt is a discovery file (what is on your site), NOT a permission file (whether AI may crawl/train). For permissions, the AI Crawler block on the Indexing tab remains the correct mechanism.
* New: Admin notice after update — a one-time, dismissable notice points administrators directly to the Setup tab when llms.txt is enabled but the new blocks have not been reviewed yet. Stored per user, not globally.

Translations:
* Improved: All 13 locale translations regenerated with full coverage of the new strings (DACH variants in du-form and Sie-form, French, Spanish, Italian, Dutch in du-form and Sie-form, English US and GB, with Swiss spelling for de_CH variants).
* Improved: Migration runs once on plugin update – existing intro text is copied into the new Summary field, default sections and exclude slugs are seeded, no manual setup required.

1.5.0 – 09.05.2026

• New: WooCommerce variation URL noindex – product variation URLs (?attribute_), layered-nav filters (?filter_, ?pa_*, ?min_price, ?max_price, ?rating_filter, ?query_type_*), sort modifiers (?orderby on listings) and cart actions (?add-to-cart, ?removed_item, ?undo_item) are automatically excluded from search engine indexing.
• New: Setting “WooCommerce variation URLs” under Settings → Indexing & AI Crawlers – on by default, can be disabled if your setup requires variation URLs to be indexed.
• Improved: Detection runs early in wp_head (priority 1) and outputs noindex, follow so that internal links on the page are still crawled.
• Improved: Canonical URL on variation pages still points to the main product, consolidating ranking signals to the correct URL.
• New: Dedicated “WooCommerce Friendly” section in the readme with the full list of recognised query patterns.
• Note: This setting only applies when WooCommerce is active. No effect on non-WooCommerce sites.

1.4.0 – 08.05.2026

• New: 301 Redirect Manager – dedicated “Redirects” submenu under SEO & Title with a clean admin UI to add, edit and delete redirects inline.
• New: Path-based redirect matching – enter just the path (/old-page) for the source URL; trailing slashes and query strings are normalised automatically when matching.
• New: Internal and external redirect targets – redirect to another path on the same site or to an absolute http(s):// URL.
• New: Hit counter and last-hit timestamp per redirect – see at a glance which redirects are actively used.
• New: Loop and duplicate detection at save time – self-loops, reverse loops between two redirects and duplicate source URLs are blocked with clear error messages.
• New: Object cache for the redirect map and deferred hit counter on shutdown – redirects stay fast even with many entries.
• New: Database table {prefix}sdstd_redirects is created on activation via dbDelta and dropped on uninstall.
• Improved: Plugin description and feature list updated to reflect the new redirect manager; new “Redirects” section in the readme.

1.3.3 – 07.05.2026

• Improved: Plugin Check compliance – all output values in class-sdstd-llms-txt.php are now properly escaped (16 fixes in the llms.txt / llms-full.txt generator).
• Improved: XSL stylesheet output in class-sdstd-sitemap.php now uses explicit esc_html() on all interpolated values for full Plugin Check compliance.
• Improved: Translator comments added to all i18n strings containing placeholders (%d, %1$d etc.) in class-sdstd-admin-assets.php for accurate translation context.
• Improved: Ordered placeholders (%1$d instead of %d) for the multi-value import-result message so translators can reorder them per locale.
• Improved: Removed suppress_filters => true from sitemap query – plugin filters now run as expected.
• Improved: Documented direct database queries and slow meta/tax queries in class-sdstd-sitemap.php with phpcs annotations and rationale (all results are cached in the sitemap transient for 1 hour).
• Improved: phpcs annotations on the importer’s prepare() calls explaining the safe use of dynamically-built %s placeholder lists.
• Improved: Annotated the WordPress core the_content filter usage in the FAQ schema generator (this is intentionally not a plugin-owned hook).
• Note: No functional or user-facing changes. All fixes are static-analysis cleanup for the WordPress.org Plugin Check.

1.3.2 – 05.05.2026

• New: Per-post AI crawler override – set “Block” or “Allow” individually for each page in the Indexing tab. Use cases: block AI on premium/member content, or explicitly allow AI on marketing pages even when blocking is global.
• New: Tristate dropdown “Use global setting / Block / Allow” replaces the previous read-only AI status display in the meta box.
• New: Live preview in the meta box now shows the effective AI-blocking meta tag based on per-post override + global setting.
• New: Post meta _sdstd_ai_bots_override available via REST API for headless setups.
• Improved: AI crawler logic in class-sdstd-indexing.php respects per-post override on singular pages, falls back to global setting elsewhere.
• Improved: llms.txt and llms-full.txt now exclude posts where AI override is set to “Block” (in addition to the existing noindex filter). Setting a page to block AI now keeps it out of both meta tags AND the llms.txt feed consistently.

1.3.1 – 05.05.2026

• New: Filter sdstd_schema_author_url – allows other plugins or themes to override or remove the author URL in Schema.org Article markup. Return an empty string to omit the author URL entirely.
• New: Filter sdstd_sitemap_author_url – allows other plugins or themes to override the author archive URL in the XML sitemap. Return an empty string to skip the author entirely.
• Improved: Compatibility with security plugins that block author archives (e.g. Super Duper Two-Factor Login). When author archives are blocked and redirected, the new filters prevent dead URLs from appearing in structured data and sitemaps.
• Note: No breaking changes. Default behaviour is unchanged unless a filter is explicitly hooked.

1.3.0 – 27.04.2026

• New: XML Sitemap – generates a single /sitemap.xml file containing all public content
• New: Image Sitemap extension – featured and OG images included for better Google Image Search visibility
• New: Granular content selection – Posts, Pages, Products, Custom Post Types, Author archives and Date archives included by default; Categories and Tags optional
• New: Respects per-page noindex – pages marked as noindex are automatically excluded from the sitemap
• New: WordPress core sitemap (/wp-sitemap.xml) automatically disabled to avoid duplicates
• New: Dedicated “Sitemap” submenu under SEO & Title with submission links to Google Search Console, Bing Webmaster Tools, Yandex and IndexNow
• New: Browser-readable XML stylesheet (/sitemap.xsl) for human-friendly sitemap viewing
• New: Smart caching via transient (1 h, auto-invalidated on content changes) for fast response times
• Note: The classic sitemap ping endpoints have been discontinued by Google (26.06.2023) and Bing (2022). The plugin uses webmaster tools and IndexNow instead.

1.2.1 – 06.04.2026

• New: REST API support – all SEO meta fields readable and writable via the WordPress REST API
• New: SEO Data Importer – import from Yoast SEO, Rank Math, SEOPress and All in One SEO with data detection and overwrite protection
• New: Focus Keyword Analysis – live 10-point SEO check (title, description, URL, content density, headings, image alt tags, text length, links)
• New: Schema.org JSON-LD – automatic Article, WebPage, Product, BreadcrumbList and WebSite schemas with per-page type override
• New: FAQPage schema auto-generated from H2/H3 headings in content
• New: Indexing tab – noindex/nofollow per page with live robots meta tag preview
• New: Canonical URL override per page (replaces WordPress default canonical)
• New: AI Crawler Blocker – block GPTBot, Google-Extended, CCBot, Anthropic, Bytespider, FacebookBot and Applebot-Extended
• New: llms.txt – generates /llms.txt and /llms-full.txt with site summary for AI systems
• New: 5-tab layout (SEO, Keywords, Social Media, Schema, Indexing)
• New: Respects WordPress “Discourage search engines” setting – never overrides, warns in UI
• New: Import safety – original data from other plugins is never deleted or modified
• Changed: Minimum PHP version raised to 8.2
