Super Images

PHP-FPM / nginx 502 with libvips: isolate image work from the FPM process (prefer native vips CLI; fall back to a PHP CLI worker), matching the ExpressionEngine mitigation
Unavailable explicit driver preference now falls through to the next usable driver instead of failing hard
GD / Imagick availability probes are stricter (real usability in the current SAPI, not “extension mentioned”)
Playground result meta matches the demo-style pills (dimensions / size / duration) with an open-in-new-tab link instead of a raw storage path
Dashboard health stays Healthy on optional warnings; preferred/selected Libvips (or pinned driver) problems are elevated to fail so the badge shows Needs attention

LibvipsCliBridge + bin/libvips-worker.php for safe libvips under FPM
Isolated pipeline path in GenerationService (native encode under isolation; Imagick/GD fallback on native failure)
Docs: full Drivers Ubuntu (+ Herd) install guides and FAQs; expanded Diagnostics, encoder tradeoffs, getting-started / CP cross-links
Diagnostics: precise “why unavailable” details + install suggestions; FFI check; Imagick + Libvips dual-driver check; fail when no driver is usable; warn when pinned driver is unusable
Example / project config comments for encoder effort / method / progressive tradeoffs
.env overrides documented for SUPER_IMAGES_VIPS_BINARY / SUPER_IMAGES_PHP_BINARY / SUPER_IMAGES_VIPS_ISOLATE

Dashboard “Doctor” panel renamed to System Health; CLI doctor header prints Diagnostics
Driver manager logs and falls back when a requested driver is missing

Initial public release for Craft CMS 5.

Unified GenerationService — one pipeline for Twig, Control Panel, CLI, queue, and signed runtime URLs
Deterministic derivative paths and generation identity hashing (config/ops changes produce new files, not stale cache)
File-based existence tracking — no GeneratedImage database table; derivatives live on the configured storage adapter
Per-request memoization for existence checks and generation planning

GD, Imagick, and Libvips (jcupitt/vips) drivers with automatic auto fallback (libvips → imagick → gd)
Native encode for JPEG, PNG, WebP, and AVIF
Geometry operations: resize, crop, fit, fill, scale, rotate, flip
Color operations: grayscale, brightness, contrast, saturation, sepia, invert
Effects: blur, sharpen
Composition: watermark, text overlay, image overlay, padding, border, background

Configurable encoders (quality, metadata stripping, custom CLI argument maps)
External optimizers: jpegoptim, oxipng, optipng, pngquant, cwebp, avifenc
optimizeType setting — defer same-format post-optimizers to the Craft queue (job) or run inline (runtime)
PNG→WebP/AVIF via cwebp / avifenc with native fallback (never ships PNG renamed as .webp)
OptimizeDerivativeJob — reads stored object (local or remote), optimizes, overwrites same path/URL

craft.superImages.url(), img(), picture(), srcset(), tryGenerate(), generate()
