Calucon Third-Party Embed Gate

Changelog

0.12.1

• Changed: the German translation was reviewed by the German translation team at translate.wordpress.org and corrected against their glossary and style guide. The Appearance tab is now called “Design”; “Reiter” became “Tab”, “Rahmen” became “Rand”, “Eigene” became “Individuell” where the English says “custom”, and a few sentences were rewritten because they read like English rather than German. Nothing changed for sites running in English.
• Internal: translations now go through a staged pipeline that verifies de_DE and de_DE_formal against the style guide and the glossary before deriving de_AT, de_CH and de_CH_informal — so a wrong word can no longer be copied into five locales at once.

0.12.0

• New: German translations ship with the plugin, for all five German locales WordPress offers — Deutschland (du und Sie), Österreich, and Schweiz (Sie und du, written with ss instead of ß as Switzerland does). WordPress does not fall back between them, so each one needs its own file. Everything a person reads is covered: the placeholder your visitors see, all five settings tabs and the per-block controls in the editor. Set the site language to German and it follows; a translation from translate.wordpress.org still takes precedence over the bundled one.
• Changed: the plugin loads its own translation files only on WordPress below 6.8, which is where it measured that WordPress stops finding bundled files by itself. Newer sites run without that call, as the plugin directory prefers. Nothing changes for sites running in English.
• New: the Compatibility overview names a detected multilingual plugin (WPML, Polylang, TranslatePress, Weglot) and says where the texts you typed yourself are translated — for WPML and Polylang, the screen that holds them; the other two translate the finished page and need nothing.
• Fixed: on WordPress older than 6.8, the bundled German never reached the block editor’s own controls — the front end and the settings screen were translated, the editor was not. wp_set_script_translations() was not being told where the plugin keeps its translation files, so WordPress looked only in the language-pack directory.
• Fixed: on WPML and Polylang sites, the texts you type yourself — a provider’s notice, button label or privacy-policy URL, and your own providers’ names — showed in the site’s default language on every translation. They are now read in the language of the page being built. Translate them in WPML’s String Translation or Polylang’s Strings screen; the shipped wpml-config.xml already registers them.

0.11.0

• New: page caches are flushed automatically when the plugin is activated and after it updates, not only when settings are saved or the plugin is deactivated — so a cached page cannot keep serving pre-update markup.
• New: the Providers tab is grouped by what the embed is (video, audio, social, documents…) with a filter box, so a long list stays manageable — and it no longer scrolls sideways on a phone. Each provider’s wording and privacy-policy link sit behind a per-provider toggle.
• New: the content scan on Status & tools is now actionable. Every embed it finds can be named (so an unknown host gets a proper label and icon) or let through, without typing a host name anywhere — and hosts you have let through are listed with a one-click undo. Nothing changes until you press Save.
• Changed: the Dailymotion test fixture pointed at a re-uploaded television series; test fixtures now use placeholder ids unless the target is the provider’s own, an institution’s own, or ours.
• Fixed: the “Withdraw embed consents” control sat against the left edge of the page on block themes instead of lining up with the text around it.
• Fixed: the settings screen’s read-only tables (Compatibility, the content scan, the Content-Security-Policy host list) pushed the page sideways on a phone; they now scroll within their own box.
• Fixed: on narrow screens the placeholder could be taller than the space reserved for the embed, hiding the fallback and privacy links behind a scrollbar that was easy to miss. The panel now grows to fit.
• Fixed: an embed whose script reserves an empty box of its own (Calendly’s inline widget) left a tall blank gap above the placeholder; the gap is gone while gated and comes back when the embed loads. Calendly placeholders now link the booking page instead of the script host.
• Fixed: the settings screen could claim “unsaved changes” after merely switching tabs or opening a section. Only changing a value counts now.
• Fixed: Scribd embeds (an inline script that fetches Scribd’s loader), VideoPress embeds (a resize loader) and Wolfram Cloud notebooks (stylesheets and an inline call) requested their provider before the click; these companions are now gated with their panel and load only after it. Scripts of your own that merely mention a provider’s address are left alone.
• Fixed: a script of your own that merely names a provider’s address in a comment could be removed and replaced with a placeholder, so the script stopped running. A provider address now only counts where a script actually loads it.
• Fixed: a second embed from the same provider on one page lost its placeholder and its link, and loaded on the first embed’s click. Each embed is its own again.
• Fixed: a placeholder for a Scribd or Crowdsignal embed that came with no address to link to could show a broken “Open on …” link. It now links the provider’s site.
• Fixed: with consent memory or a consent platform enabled, a returning visitor could get an embed that stayed blank because its loader ran before the script it needs. Also, remembering consent “for this embed only” treated every script-built embed as the same one, so a click on one could load another provider’s embed on the next page view.
• Fixed: a placeholder inside a <noscript> block (Crowdsignal polls) offered a button that could never work, since that markup is only shown when scripting is off. It shows the notice and the link instead.
• Fixed: “Name this host” put a host found as a script into the embed-hosts field, where it matched nothing.
• Fixed: after running the content scan, the “Check what is on my site” button on the Providers tab did nothing — it now takes you back to the results.
• Fixed: the block editor’s script and stylesheet were the last ones not cache-busted per build, so a rebuilt same-version install could keep the previous editor script.
• New: built-in providers for the rest of WordPress core’s embed types — Dailymotion, TED, VideoPress and WordPress.tv, Mixcloud, Pocket Casts, Scribd, Speaker Deck, Issuu, Kickstarter, Wolfram Cloud and Amazon Kindle (players and documents), plus Imgur, Tumblr, Pinterest, Bluesky and Crowdsignal (script embeds, now with a real fallback link to the post instead of the script host). All of these were gated before under their host names; they now get a name, an icon, a privacy-policy link and a Providers-tab row.

0.10.0

• New: an optional privacy-policy link in each placeholder, pointing at the provider’s own policy page (for the built-in providers that declare one; unknown embeds have no known policy). Off by default — a checkbox on the Providers tab turns it on.
• New: fine-grained appearance controls without CSS — custom corner radius, border width and colour, shadow strength, panel spacing, button size, an optional bundled play glyph on the button, notice text size and panel alignment, all mirrored in the live preview.
• New: the “Withdraw embed consents” control is now styled to match the panels (same colours and corners) with filled, outline and text-link variants.
• New: optional dark-mode colours, applied only when the visitor prefers a dark colour scheme.
• New: the Appearance tab is organised into sections with a one-click “Reset appearance to defaults”.
• New: load-button style (filled or outline), full-width option and hover strength; panel placement over poster images (corner card, centred card, or bottom bar) with a poster preview in the settings.
• New: per-embed button and notice text in the block editor, next to the existing gate override and poster controls.
• New: quick styles — four one-click starting points (Dark cinema, Light minimal, Brand card, Soft pastel) that fill in every Appearance control for you to tweak.
• New: the button icon is now chosen by what the embed is — play for videos, a pin for maps, a note for audio, a generic symbol otherwise; poster dimming; a separate link colour; a phone-width preview toggle.
• New: multilingual sites — the custom notice and button texts (settings and per block) are registered for WPML and Polylang via a shipped wpml-config.xml.
• New: per-provider privacy policy URL override on the Providers tab, for a localised or moved policy page (https only).
• New: a “Settings” link next to the plugin on the Plugins screen, and a “Support development” link in its row details.
• New: your own providers — name any embed host on the Providers tab (with optional script hosts and a kind for the button icon); it then gets the same note, button text and privacy-policy link controls as the built-ins. No code needed — and nothing to break: unknown hosts are gated either way, hosts a built-in provider handles are refused with a notice, and your own providers are always gated.
• New: ten provider kinds for the button icon — video, map, audio/podcast, social post, form, calendar/booking, document, image/GIF, 3D/virtual tour, generic — each with its own glyph; the built-ins are classified accordingly (X, Instagram, Facebook, Reddit and Strava as social posts; Typeform and Google Forms as forms; Calendly and Google Calendar as calendars; Matterport and Sketchfab as 3D; GIPHY as image), and the Providers tab shows every provider’s icon.
• New: the Content-Security-Policy section (Status & tools) now explains in plain language whether you need it at all, can check your own home page from the browser for an existing policy and say which provider hosts it still lacks, offers a Copy button, and lists which provider needs which host. It is collapsed by default — most sites send no policy.
• New: every colour can follow one of the theme’s own palette colours by name — the panel then changes with the theme — or be set to a custom colour; the pickers also offer the palette as named swatches.
• Fixed: a placeholder with a poster image could show a dead scrollbar — the image now always fits the reserved box, whatever its ratio.
• Fixed: right-to-left sites (icon and status spacing now follow the text direction) and Windows High Contrast mode (panel, buttons and icon keep visible borders).
• Fixed: the error state after a failed load could link the wrong destination when the panel showed more than one link.

0.9.4

• Performance and robustness: the embed detector now handles pathological markup (thousands of unterminated code blocks) in linear time instead of quadratic, the zero-embed fast path is ~4x cheaper on every page view, and resource-hint scrubbing skips pages with no hint tags at all.
• Front end: with consent memory enabled, remembered consents are now restored with a single storage read per page instead of one per embed; a failed embed-SDK load no longer leaves a dead script element behind, a retry can no longer lose the placeholder, and withdrawing a platform consent now also clears a stale error notice.
• Internal clean-up with no behaviour change: dead code removed, asset handling and the settings screen reorganised, and the unused thumbnail provider-descriptor key (a leftover of the rejected auto-fetch feature) removed.

0.9.3

• The source repository moved to github.com/Calucon/calucon-third-party-embed-gate, matching the plugin slug; the security-report and issue links were updated accordingly (the old address redirects). No functional change.

0.9.2

• The Status screen’s scan query parameter now carries the full plugin prefix (calucon-embed-gate-scan). No functional change.

0.9.1

• When “Gate the whole page output” is enabled, the plugin’s stylesheet and script are now delivered through the standard enqueue API on every front-end page instead of being written into the buffered document at shutdown. Direct tag injection is gone entirely.
• The translation bridge for the WordPress-free layers now resolves through a generated map of literal gettext calls (languages/strings.php), so no translation function in the plugin ever receives a variable argument.
• The provider descriptor key hint_hosts is now scrub_hint_hosts — a clearer name for what it always was: hostnames whose preconnect/dns-prefetch resource hints the plugin removes. Nothing is ever requested from them.
• Fixed the Cloudflare cache-purge integration: it now registers with the official Cloudflare plugin’s cloudflare_purge_everything_actions filter and fires the plugin’s own calucon_embed_gate_flush_caches action (the previous direct hook call never reached the Cloudflare plugin). The LiteSpeed purge hook now fires only when LiteSpeed Cache is installed.

0.9.0

• Before the WordPress.org listing goes live — while no installed sites exist to break — the plugin’s internal identifiers were aligned with its new name, with no legacy aliases: filters and actions are calucon_embed_gate_*, the shortcode is [calucon_embed_gate_withdraw], the block is calucon-embed-gate/withdraw, the WP-CLI namespace is wp calucon-embed-gate, the theme template override directory is {theme}/calucon-embed-gate/, and the settings option was renamed. If you somehow installed a pre-release build, update those references and re-save the settings.
• The .cg-embed CSS classes, --cg-* custom properties and data-cg-* attributes are unchanged.

0.8.1

• Renamed the plugin’s constants to match the plugin: CALUCON_EMBED_GATE_VERSION, FILE and _DIR. The previous CONSENT_GATE* names remain defined as aliases and will be removed no earlier than 0.9.0, in a release of their own.
• Updated the plugin page and demo links to their new addresses.
• Everything a site can depend on is unchanged: the calucon_embed_gate_* filters, the [calucon_embed_gate_withdraw] shortcode, the wp calucon-embed-gate CLI commands, the .cg-embed CSS classes and the theme template override path all keep their existing names. Nothing you have already set up needs changing.

0.8.0

• Renamed from “Consent Gate” to “Calucon Third-Party Embed Gate” (new slug calucon-third-party-embed-gate) during WordPress.org review, to make clear the plugin gates third-party embeds and is not a consent management platform. No functional change.
• Translations: the strings defined in the WordPress-free layers are now mirrored in languages/strings.php as literal gettext calls, so translate.wordpress.org can extract them. Removed the redundant load_plugin_textdomain() call (WordPress loads language packs automatically since 4.6).
• readme: added the “External services” section stating what the plugin does (and does not) contact.

0.7.5

• Compliance: documented the WordPress-free layer’s parse_url() usage and replaced a WordPress 6.5-only function with a version-agnostic equivalent, so the plugin passes WordPress Plugin Check cleanly on the 5.9 minimum. No functional change.

0.7.4

• Documentation: added Installation and Screenshots sections to the readme for the WordPress.org listing, and linked the plugin page and live demo. Plugin URI now points to the plugin’s home page. No functional change.

0.7.3

• Repository renamed to match the plugin (github.com/Calucon/consent-gate). Updated the Plugin URI and the issue/security-report links. No functional change.

0.7.2

• Added an optional way to support development: a Donate link, a support link in the plugin’s own settings footer, and a GitHub Sponsor button. Plain links only — no third-party widget or remote image loads, so the plugin still makes no outbound request from wp-admin.

0.7.1

• Security hardening (pre-submission audit). Closed a host-classification gap where a crafted embed URL using a backslash or irregular slashes in its authority (e.g. https://evil.example\@yoursite/) parsed to your own host in PHP but connects to the third party in every browser — such URLs are now gated, matching how browsers resolve them. The fallback link now rejects non-navigable schemes (javascript:, data:), the inline settings JSON is emitted with the same tag-escaping as the embed payload, and provider note/button overrides are length-capped.
• Robustness: when a script-strategy SDK (X/Twitter, Instagram, …) is blocked by the browser, the other embeds of that provider keep their panels and fallback links instead of disappearing until reload.
• Every plugin PHP file now carries a direct-access guard, and the plugin declares its Domain Path — housekeeping for the WordPress.org directory.

0.7.0

• Consent platform bridge (off by default): when an installed, tested consent platform — WP Consent API, Complianz, Cookiebot, CookieYes, Borlabs Cookie 3, or Real Cookie Banner — reports consent for the embeds’ category, gated embeds load without a second click, and a withdrawal in the platform re-gates what the bridge loaded (an embed the visitor clicked personally stays). Client-side and read-only: the bridge stores nothing, sends nothing, and with an untested platform or no answer gating stands unchanged.
• IAB TCF v2.2 signals can additionally be honoured behind their own experimental flag; only providers with a Global Vendor List entry can ever be granted that way.
• The Compatibility screen now distinguishes tested platforms (bridge available or active) from untested ones (fail-closed, as before).

0.6.1

• Legacy Google Maps embeds (maps.google.com/maps?q=…&output=embed, the older share form that is still widespread) are now recognised as Google Maps instead of falling back to the generic gate. They were already gated either way; they now get the Google Maps label, note and resource-hint scrubbing.

0.6.0

• Poster images: every embed block gains a “Set poster image” control (Calucon Third-Party Embed Gate panel in the block inspector). The chosen media-library image is shown behind the consent panel until the visitor loads the embed — served from your own site, never fetched from the provider, so the zero-third-party-requests guarantee is untouched. The panel keeps its solid background on top of the image, so text contrast is preserved.
• Theme placeholder templates receive the poster as a $poster variable; see docs/customizing.md.

0.5.0

• WP-CLI: wp calucon-embed-gate scan reports every embed in recent content and whether it is gated (--format=json for CI and automation); wp calucon-embed-gate providers lists providers as the gate resolves them. Both read-only, no outbound requests.
• Ships docs/customizing.md: a self-contained reference for customizing the plugin from functions.php or WP-CLI — descriptor keys, filter examples, the template contract, and the invariants a customization must keep. Written to serve developers and AI coding agents alike.

0.4.0

• The settings screen is now tabbed: Providers, Detection, Appearance, Consent memory, and a read-only Status & tools tab (Status scan, Compatibility, CSP snippet). One page, one Save button — saving returns you to the tab you were on.
• Tabs follow the ARIA tabs pattern (arrow keys, Home/End) and are an enhancement: without JavaScript the page renders as before, every section visible.

0.3.0

• Appearance made novice-friendly: the colour fields are now WordPress colour pickers (no hex typing), a corner-style choice (square, rounded, pill button) joins the panel-style presets, and the settings screen shows a live preview of the placeholder that updates as you change anything.
• The preview includes an automatic readability check: every colour pair (panel text, button text, fallback link) is measured against the WCAG 4.5:1 contrast minimum, in plain language, as you pick colours.
• The preview is rendered through the same pipeline as the front end — template overrides and text filters included — and is inert: the settings screen still makes no third-party request.

0.2.0

• Detection hardening: exclusion ranges are scanned sequentially, so a stray <!-- inside a script (JSON-LD, legacy script-hiding) or an unclosed <pre> can no longer disable gating for the rest of the page.
• Gates attribute-swapped lazy loading (data-src, data-lazy-src, data-original), legacy <embed>/<object> markup, and srcdoc embeds that reference third parties; invisible tracking iframes (zero-sized, display:none) are removed instead of becoming a visible dead panel.
• Gates content delivered to visitors over AJAX and REST (“load more”, infinite scroll); editors keep seeing original markup. New surfaces: Text-widget visual mode, comments and term/archive/author descriptions on classic themes.
• Whole-page gating repaired for page-builder sites: styles and scripts are injected into the buffered page (buttons work now), scanning is scoped to the body, and hint tags printed by performance plugins are scrubbed.
• Activation fixes: unknown widgets no longer share one consent/removal group (scoped per host); id, name, class and data-secret survive the rebuild, so the YouTube JS API, <form target> and WordPress-to-WordPress embed resizing work after consent; loading and error states are announced to assistive technology, with a link to the provider as the error fallback.
• Resource hints: preload/prefetch/prerender covered, the wp_preload_resources filter hooked, and providers’ sibling CDN hosts scrubbed.
• Feeds carry a plain fallback link where an embed was removed.
• New: per-block “Gate this embed” override and a withdrawal block in the editor; Appearance presets and colours; Compatibility and Status screens; always-gate host list; opt-in third-party image gating.
• Providers registered from a theme’s functions.php now appear in the settings table, the CSP snippet and hint scrubbing; five new documented hooks.
• Multisite-aware uninstall; page caches are flushed on deactivation.
• The full E2E, accessibility (axe) and real-WordPress integration suites now run in CI on every change.

0.1.0

• Initial release: core gate (minification-tolerant scanner, host matcher, iframe and script rules), built-in provider set with privacy-preserving load targets, server-rendered accessible placeholder, settings screen, template override, feeds/excerpts/widgets/resource-hint handling, opt-in consent memory with withdrawal shortcode, CSP snippet generator.
