Ændringslog

3.3.3

Added: Settings for output quality (60–100): WebP when WebP thumbnails are enabled; separate JPEG/lossy and PNG compression when serving original formats.
Added: Admin UI toggles quality fields based on the “Generate WebP” option; PNG uses zlib/Imagick compression strength (lossless pixels).
Fixed: PNG encoding compatible with PHP 8+ (removed invalid extra argument to Intervention Image PNG encoder).
Fixed: Smart compression reference PNG creation uses a proper image clone.

3.3.2

Added: Support for conversion at original size — when thumb is 'full' or [0, 0], images are converted (WebP and original format) without resizing.
Added: In liteimage_downsize(), size [0, 0] now returns the original image dimensions.
Added: In get_thumb_size(), support for 'full' and [0, 0] with correct size_name in format liteimage-{width}x{height}.
Fixed: Safe reading of width/height from attachment metadata in liteimage_downsize() when keys are missing.

3.3.1

Fixed: Thumbnail filename conflicts when multiple images share the same filename. Added attachment ID to thumbnail filenames to ensure uniqueness.
Fixed: Format changed from {filename}-{size_name}.{ext} to {filename}-{attachment_id}-{size_name}.{ext} for all thumbnail variants (WebP, original format, and retina @2x versions).

3.3.0

Added: Gutenberg block LiteImage Image with full responsive controls for desktop/mobile sources, breakpoints, and HTML attributes.
Added: PHPUnit smoke test covering block attribute sanitization.
Added: Automatic 2x retina variants for all generated LiteImage sizes, including Gutenberg block output.
Changed: Refreshed plugin icon to match the new brand palette.
Changed: Updated documentation with block usage instructions and retina guidance.

3.2.1

Fixed: Unescaped output in admin tab navigation (WordPress.org Plugin Check compliance)
Fixed: Removed deprecated load_plugin_textdomain() call (WordPress auto-loads translations since 4.6)
Fixed: Updated readme.txt headers to match plugin requirements (Tested up to: 6.8, Requires at least: 5.8)

Fixed: WordPress.org Plugin Check compliance – all errors and warnings resolved
