Changelog

[Unreleased]

[3.0.0] - 2021-11-23

Added

Change

  • ETag generator & checker uses source image ETag when possible.
  • 304 Not Modified responses includes Cache-Control, Expires, and Vary headers.
  • dpr processing option doesn't enlarge image unless enlarge is true.
  • imgproxy responds with 500 HTTP code when the source image downloading error seems temporary (timeout, server error, etc).
  • When IMGPROXY_FALLBACK_IMAGE_HTTP_CODE is zero, imgproxy responds with the usual HTTP code.
  • BMP support doesn't require ImageMagick.
  • Save GIFs without ImageMagick (vips 8.12+ required).

Fix

  • Fix Client Hints behavior. Width is physical size, so we should divide it by DPR value.

  • Escape double quotes in content disposition.

Removed

  • Removed basic URL format, use advanced one instead.
