SDWebImage v5.6.0 Release Notes

Release Date: 2020-03-05 // about 4 years ago

  • 🔋 Features

    URLSession Metrics

    • ➕ Added the URLSessionTaskMetrics support for downloader && operation, which can be used for network metrics #2937
    • Typically you use custom operation class to collect all metrics in your app. You can also collect metrics for single url request level. Check the #2937 example code to grab the download token and check metrics.

    Vector Image

    • 🔋 Feature - better support for vector format detection, now PDF rasterized bitmap is built-in #2936
    • Pass .thumbnailPixelSize to control the PDF bitmap size. If you want vector PDF rendering, you still need to use SDWebImagePDFCoder.
    • Vector image like SVG (via SDWebImageSVGCoder) and PDF (via SDWebImagePDFCoder), or system symbol images, can be detected by new API sd_isVector.
    • 0️⃣ Vector image does not pass to transformer by default, because they support dynamic size changing. Pass .transformVectorImage option to allow transformation.

    Cache

    • ➕ Add a better check to handle the cases when call storeImage without imageData #2953
    • Which means, if you store image to disk without data, we will use extra information via sd_imageFormat or custom image class, to choose the the image format (including GIF and PDF) for encoding. Previously we only encode it into PNG or JPEG.

    Context Option

    • 🔋 Feature add context option for cache, loader and coder, deprecated SDWebImageContextCustomManager #2955
    • This makes it easy to use custom loader, cache, and decoder, without need to create a dummy SDWebImageManager instance.

    🛠 Fixes

    • 🛠 Fix the rare case when call SDWebImageDownloaderOperation.cancel, the completion block may callback twice #2954

    ⚠ Warnings

    • 🚀 Suppress the deprecation warning when min deployment target version set to iOS 13+ or macCatalyst
    • Complete all the SDWebImage error code with the localized description, make it easy for debugging #2948
