This update further improves handling of ostree installer images. We 'correct' the image dicts for the images the current Pungi release is producing (the filenames have been improved to have -ostree- in them, but the type is still boot). When synthesizing image dicts for releases without metadata, we catch more ostree installer cases to assign the dvd-ostree type to.

This update also will find many more images for Alpha, Beta and stable releases. This is because when these releases are synced to the public mirrors, they are actually split into two trees. Most of the bits go into the 'main' tree, which is found under /fedora/ on the mirrors, but some lesser-used deliverables are split into a separate tree found under /alt/ on the mirrors. Previously, fedfind was not aware of this and would only find images in the 'main' location, it did not find any of the images that were split off to the alt location. Now, fedfind does find these images.

If you use the fedfind CLI, you do not need to do anything special; queries for Alpha, Beta and stable releases will now show these images where they did not before.

If you have code using the fedfind module, be aware that the MirrorRelease subclasses now have a alt_location property which is the full URL to the top-level location of the alt tree for the release, and in the synthesized metadata and thus also in the all_images list, the image dicts have an additional property, alt, which indicates whether the image is the main tree or the alt tree. To get the correct URL for an alt image, concatenate its path with the release's alt_location property. If you only deal with non-split releases that have metadata - like the nightly composes - nothing should change for you.
