Changelog

This file contains all notable changes to imageproxy. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Changed

updated docker image to use go1.12 compiler and build imageproxy as a go module.
options are now sorted when converting to string. This is a breaking change for anyone relying on the option order, and will additionally invalidate most cached values, since the option string is part of the cache key.

Both the original remote image, as well as any transformations on that image are cached, but only the transformed images will be impacted by this change. This will result in imageproxy having to re-perform the transformations, but should not result in re-fetching the remote image, unless it has already otherwise expired.

Removed

removed deprecated whitelist flag and Proxy.Whitelist struct field. Use allowHosts and Proxy.AllowHosts instead.

0.8.0 (2019-03-21)

Added

added support for restricting proxied URLs based on Content-Type headers (#141, ccbrown)
added ability to deny requests for certain remote hosts (#85, geriljaSA)
added userAgent flag to specify a custom user agent when fetching images (#83, huguesalary)
added support for s3 compatible storage providers (#147, ruledio)
log URL when image transform fails for easier debugging (#149, daohoangson)
added support for building imageproxy as a go module. A future version will remove vendored dependencies, at which point building as a module will be the only supported method of building imageproxy.

Changed

when a remote URL is denied, return a generic error message that does not specify exactly why it failed (7e19b5c)

Deprecated

whitelist flag and Proxy.Whitelist struct field renamed to allowHosts and Proxy.AllowHosts. Old values are still supported, but will be removed in a future release.

Fixed

fixed tcp_mem resource leak on 304 responses (#153, Micr0mega)
