Release v26.19.02

Added

• New Delivery fieldset:
  • Image delivery toggle to suspend image rewriting without uninstalling.
  • Video delivery toggle — proxies <video src>, <source type="video/*">, and rewrites <video poster> images. Off by default; enable only after configuring video delivery on the ImageKit account.
  • Reject paths — one glob pattern per line (*, **, ?, # comments) for site-wide path-based exclusion.
• New Asset proxying fieldset (opt-in, requires a web origin configured on ImageKit):
  • Template assets — proxy CSS/JS/fonts under templates/ and media/templates/.
  • Extension assets — proxy CSS/JS/fonts under media/com_*, media/mod_*, media/plg_*, media/lib_*, and the legacy components/, modules/, plugins/, libraries/ paths.
  • Core assets — proxy Joomla core CSS/JS/fonts under media/system/, media/vendor/, media/legacy/, media/cms/.
• New Status diagnostics panel (custom StatusField): live configuration overview, sample rewritten image and asset URLs, and a copy-paste plain-text report (no secrets) for support tickets.
• Per-image opt-out: data-ik-skip on any <img> leaves that image alone; the attribute is stripped before the HTML reaches the browser.
• Extra transformations setting — comma-separated tokens appended to every image URL after w/q/f-auto (e.g. pr-true,c-at_max for progressive JPEG + max-fit cropping).
• Opt-in Strip "-WxH" suffix setting. When enabled, filenames like photo-300x200.jpg are reduced to photo.jpg and the dimensions are passed as tr:w-300,h-200 so ImageKit can serve the canonical original at any size. Off by default to stay safe with extensions whose origin only stores sized variants.
• srcset density descriptors (2x, 3x) now resolve to the correct render width using the <img>'s native width as the base.
• <picture> / <source srcset> and lazy-loader attributes (data-src, data-srcset) are now rewritten alongside <img>.
• ImageKitHelper::buildAssetUrl() builds a passthrough (no tr:) URL for non-image assets.
• ImageKitHelper::buildUrl() and buildSrcset() accept an optional extraTokens parameter for per-call transformations.

Changed

• loading="lazy" is no longer added when fetchpriority="high" is present. The two are semantically conflicting (LCP hint vs. defer); honouring the author's priority hint matches modern Core Web Vitals guidance.
• Original quote style on rewritten attributes (src=, data-src, srcset, href, poster) is preserved instead of being normalised to double quotes.
• ImageKitHelper::configure() now also accepts extraTransformations and rejectPaths.
• Plugin description rewritten to reflect image, video, and optional asset delivery.
• Internals: declare(strict_types=1) in the helper, typed class constants, and #[\Override] on getSubscribedEvents() (PHP 8.3 polish).
