Release Notes

imgproxy/imgproxy (ghcr.io/imgproxy/imgproxy)

v4.0.0

Compare Source

Added

• (pro) Add internal cache for processed images.
• (pro) Add digital camera raw formats support (loading only).
• (pro) Add crop_objects processing option to crop the image to detected objects.
• (pro) Add thumb_hash info option to calculate ThumbHash of the source image.
• (pro) Add phash info option to calculate perceptual hash of the source image.
• (pro) Add classify info option to classify objects in the source image using a classification model.
• Add IMGPROXY_PRESERVE_HDR config. When set to true, imgproxy will try to keep the image's bits per pixel when possible.
• Add preserve_hdr processing option to override the IMGPROXY_PRESERVE_HDR config on a per-request basis.
• Add IMGPROXY_OPEN_TELEMETRY_ENABLE_LOGS config to control whether to send logs to OpenTelemetry.
• Add IMGPROXY_NEW_RELIC_PROPAGATE_EXTERNAL, IMGPROXY_DATADOG_PROPAGATE_EXTERNAL, and IMGPROXY_OPEN_TELEMETRY_PROPAGATE_EXTERNAL configs to control propagation of tracing headers to external requests.
• Add IMGPROXY_S3_ALLOWED_BUCKETS, IMGPROXY_GCS_ALLOWED_BUCKETS, IMGPROXY_ABS_ALLOWED_BUCKETS, and IMGPROXY_SWIFT_ALLOWED_BUCKETS configs to allowlist buckets/containers that imgproxy can read source images from.
• Add IMGPROXY_S3_DENIED_BUCKETS, IMGPROXY_GCS_DENIED_BUCKETS, IMGPROXY_ABS_DENIED_BUCKETS, and IMGPROXY_SWIFT_DENIED_BUCKETS configs to denylist buckets/containers that imgproxy can read source images from.
• Add pretty error pages when IMGPROXY_DEVELOPMENT_ERRORS_MODE is enabled.
• Add documentation links to errors. They will be visible in logs and error reports.
• Add IMGPROXY_LAST_MODIFIED_BUSTER config to control whether to pass through the If-Modified-Since header to the image source.

Changed

• Most of the code base is refactored to improve maintainability and extensibility.
• Implemented asynchronous downloading and processing of images. This improves performance when the source image is slow to download or when processing is slow.
• Source image colorspace is now preserved when possible.
• (pro) Improved SVG minification. It is now much faster and more efficient.
• (pro) Improved autoquality. Implemented weighted DSSIM calculation and trained new ML models for JPEG, WebP, AVIF, and JPEG XL.
• IMGPROXY_USE_ETAG and IMGPROXY_USE_LAST_MODIFIED are now enabled by default.
• Etag generation is now based only on Etag received from the image source and IMGPROXY_ETAG_BUSTER config.
• IMGPROXY_USE_GCS is not automatically set if the GCS key is present anymore. It should be set explicitly to enable loading images from Google Cloud Storage.
• SVG rendering DPI is changed from 72 to 96 to match W3C recommendations.
• (pro) Improved behavior of IMGPROXY_OBJECT_DETECTION_GRAVITY_MODE=one_best_centermost.
• Custom New Relic metrics are now reported as timescales. Metric names have been changed from imgproxy.X to Custom/imgproxy/X.
• Changed log formats. Option and argument names now match those in the documentation.
• (docker) imgproxy and its dependencies are now built on Ubuntu 22.04. Linux packages exported from Docker images now require a minimum libc version of 2.35.

Removed

• Removed deprecated IMGPROXY_CONCURRENCY config. Use IMGPROXY_WORKERS instead.
• Removed deprecated --keypath and --saltpath CLI arguments. Use IMGPROXY_KEY and IMGPROXY_SALT environment variables instead.
