4.0.0
The v4.0.0 release of imgix-rails introduces a variety of improvements relating to how this gem handles and generates srcset attributes. However, in releasing this version there are some significant interface/behavioral changes that users need to be aware of. Users should note that the min_width and max_width fields (passed via tag_options), as well as the widths field, have all been moved to their own encompassing srcset_options field. This is done with the intention of providing a more organized and intuitive experience when fine-tuning how srcset width pairs are generated. See the following example demonstrating this new pattern:
<%= ix_image_tag('/unsplash/hotairballoon.jpg',
srcset_options: { min_width: 1000, max_width: 2500},
tag_options: { alt: 'A hot air balloon on a sunny day' }) %>For users migrating to version 4.0 or later, it is important that all srcset-related modifiers be passed via srcset_options, as doing so through tag_options or widths directly will result in errors. For more details on these modifiers, please see the ix_image_tag or ix_picture_tag sections.
In addition to these changes, imgix-rails is now capable of producing fixed-image srcsets. Users should note that when certain dimension information is provided, imgix-rails will produce a srcset at different screen resolutions rather than the typical width pairs. This feature provides expanded functionality to cover more srcset use cases that users can take advantage of. We are always happy to provide our users with more tools to assist them in their efforts to build out responsive images on the web.
