[3.0.5] - 2018-06-27

Changed

[3.0.1] - 2018-06-04

Changed

[3.0.0] - 2018-05-21

Full public release of Release Candidate 4.

Breaking changes

  • The file upload function in CDN was recently removed. We came to the conclusion that CDN should remain a delivery tool - how a user gets their assets to their storage location for CDN to serve should be up to them. There are a great number of ways to do that, including via DADI API (see https://docs.dadi.tech/api/latest).

[3.0.0-RC4] - 2018-05-16

Added

  • #346: add basic GIF support

Changed

  • #347: gracefully handle case where domains directory does not exist
  • #354: include all image options in cache key
  • #355: return fallback image when remote server returns 404
  • #357: make config properties overridable at domain level
  • #358: update @dadi/cache to version 2.0.0
  • #359: update supertest to version 3.1.0

[3.0.0-RC2] - 2018-05-02

[1.13.3] - 2017-11-02

Changed

  • #276: ensure images can be processed with no sharpening

[1.13.2] - 2017-10-25

Changed

  • fix an issue where the aspect ratio was not respected when maxWidth/maxHeight resizes were being made

[1.13.1] - 2017-10-21

Changed

[1.13.0] - 2017-10-20

Changed

  • #270: cropping modifications to make it behave more intuitively. DevicePixelRatio is now respected, along with distorting images by providing both width & height. These changes only affect resize style crop. See the documentation for more information.

[1.12.0] - 2017-09-01

The image processor used in CDN has been replaced. We are currently pinned to Node.js 6.9.2 for most CDN installations, as lwip will not build on more recent (and less vulnerable) versions of Node.js.

We’ve now implemented Sharp in CDN. It is much faster than lwip: running a test using a Buffer as both input and output, Sharp averages 29.08 operations per second, while lwip manages just 1.87 operations per second - that's around 15 times faster.

Other than improved performance, Sharp offers us a smoother transition into adding plugin support to CDN and being able to offer features such as dynamic text and image compositing.

Changed

#243: remove restriction on configuration file names #247: respond with error when loading from a URL returns no image data

[1.11.1] - 2017-03-22

Changed

  • Remote image requests that followed a redirect sometimes return a redirect header that is a path only, without protocol and hostname. Updated the wget-improved dependency to handle this case

[1.11.0] - 2017-03-21

Added

  • #209: Add post install script to copy a sample development configuration file to the application root

Changed

  • #218: Set a default file extension of JPG for remote image requests that don't include an extension
  • #223: Ensure that querystring parameters on remote URLs are retained and passed to the remote request
  • Return 403 errors from remote requests (c31a980)

[1.10.3] - 2017-03-10

Changed

  • package.json to reduce vulnerabilities (728d4ea3)

[1.10.2] - 2017-03-07

Changed

  • return file with extension when url is extension-less (5d5774c1)

[1.10.1] - 2017-03-05

Changed

[1.10.0] - 2017-02-17

Added

  • #211: run in cluster mode by default when in production (6902d119)

[1.9.0] - 2017-02-17

Added

  • add a new configuration parameter (images.remote.allowFullURL) which toggles the use of remote images from a full URL (e.g. https://cdn.com/https://another-full-url.com/image.jpg). Allowing images to be loaded from anywhere means that people can, in theory, use my instance of CDN to load, manipulate and deliver their images on their site, so I think it should be something I actively choose to enable. (1fbde477)

  • add three additional environment variables:

    • PORT: specifies the server port
    • CACHE_ENABLE_DIRECTORY: toggles directory-based caching
    • CACHE_ENABLE_REDIS: toggles Redis caching

[1.8.2] - 2017-02-01

Changed

  • ensure uploaded files have safe filenames (6b9fea42)

[1.8.1] - 2017-01-24

Changed

  • load js files and json files in workspace (ba5b4a92)

[1.8.0] - 2017-01-18

Added

[1.7.1] - 2017-01-07

Changed

  • #84: Fix bug where the first part of the path was interpreted as a recipe/route/processor

[1.7.0] - 2017-01-05

Added

"robots": "path/to/robots.txt"

Changed

  • #155: @dadi/cache module now used in place of custom caching
  • #160: Fix: image is now returned even if no query is specified
  • #177: Fix compression when changing formats from PNG to JPG
  • #181: Removed node-canvas dependency, which was only used for determining the primary colour of an image. This is now handled by node-vibrant. Removing node-canvas simplifies the install process. If interested, you can compare results from the new module with color-thief's demo page at http://lokeshdhakar.com/projects/color-thief/.
  • #182: Fix crash when caching is enabled and a JSON response is requested (e.g. /test.jpg?format=json).
  • Modified package dependencies to include the lwip dependency using the same identifying string as used by smartcrop-lwip. This fixes the problem where NPM treated the two dependencies as separate and compiled them both when installing, extending the installation process.
  • validation added to route and recipe names, to ensure they are 5 or more characters and only a mix of letters, dashes and underscores
  • creating a Recipe by sending a POST request must now be sent to /api/recipes, not /api/recipes/new
  • replaced Bluebird Promises with native Promises
  • removed Redis dependencies, as these are now handled in @dadi/cache

[1.6.2] - 2016-10-22

Changed

When specifying only two crop coordinates, the crop rectangle wasn't being correctly set.

Using v2 of the request format, cropped images should be requested as follows:

Format of parameters: ?resize=crop&crop=top,left,bottom,right

  1. specifying the full crop rectangle: http://cdn.example.com/images/taylor_swift.jpg?resize=crop&crop=0,225,312,567
  • the image is not resized; the resulting image will be 312px x 342px
  1. specifying the top left corner of the crop rectangle: http://cdn.example.com/images/taylor_swift.jpg?resize=crop&crop=0,225
  • the size of the crop rectangle is determined by the size of the image; if the original image is 800px x 600px, the crop rectangle and resulting image size will be 575px x 600px

Adding width=400 will cause CDN to resize the image after cropping.
