sGallery v1.5.0

This release adds the image optimization chain for generated gallery images, improves WebP output for PageSpeed-friendly delivery, and includes several compatibility fixes for database portability and gallery rendering.

Added

• Added default optimization for images processed through sGallery::file().
• Added optimize() to enable or disable optimization per generated image.
• Added sharpen() for optional sharpening after resize, fit, or crop transformations.
• Added adaptive WebP quality selection for optimized images to reduce generated file size while keeping visual quality high.
• Added documentation for image optimization and sharpening.

Changed

• Generated cache filenames now include optimization and sharpening options, so different image-processing settings create separate cached derivatives.
• Automatic image format preference now uses WebP as the primary modern output format.
• Gallery sorting SQL was updated to work across different database engines instead of relying on MySQL-specific FIELD() ordering.
• Multilingual gallery field loading now uses portable SQL for locale fallback and generated src values.

Fixed

• Fixed long gallery link values by increasing the link field length from 100 to 1024.
• Fixed gallery rendering errors for unregistered item types by using optional partial includes.
• Fixed WebP output quality handling so quality 100 does not create unnecessarily heavy files by default.
• Fixed missing final newlines in touched templates/controllers.

Upgrade Notes

• Existing installations may need a database update for s_gallery_fields.link to allow values up to 1024 characters.
• Because optimization is enabled by default for sGallery::file(), generated image cache filenames will change and optimized derivatives may be regenerated on first request.
