Bug 2332519

I think the issue has a larger scope than defined.
It is my understanding that all pictures taken with Apple devices running iOS 18 (the current version) and exported as originals (*.HEIC) cannot be viewed, edited, or converted on Fedora <= 41.
So a lot of users may be delighted by such an update.
Thanks a lot for looking into it.

Yeah, this has been reported on mastodon too: https://fosstodon.org/@razze@osna.social/113962353983994440
Upstream changelog for 1.18.0 says "now reads images generated by iOS 18". 1.19.0 says "The major new feature in this release is the decoding of separate image tiles and also encoding an image tile by tile" and that it supports three tiling methods; not sure the real world impact of that, but it seems useful. 1.18.x and 1.19.x updates were maintenance/bugfix.

It doesn't look like there are any ABI changes, at least the soname wasn't bumped. (I was a bit concerned about "decoding progress is signaled to the client application and decoding can be cancelled", but looking at the code for that change, it appears to only change private functions, and the 'signalling' is done via stdout). So it should be safe to update this. Technically it might be good to request an update policy exception for this - the update policy says, for stable releases, "Updates should aim to fix bugs, and not introduce features, particularly when those features would materially affect the user or developer experience" - though in this case I'd say it's a bit debatable; from one perspective the update would be "introduc[ing] features", but from another it'd be "fix[ing] bugs".

I'll poke Neal and Dominik (who seems to have been most active in updating the package lately) about this elsewhere if I can.

I think we can go ahead and just do the update. We went through compatibility checks when updating in rawhide some time ago.

FWIW, here are some sample images that don't work with 1.17.6, but start working after updating to 1.19.x: https://github.com/mastodon/mastodon/issues/31570 -> https://github.com/user-attachments/files/16734152/HEIF-images.zip . I'll mention those in the update notes for testers.

@dominik Please fast-forward the F42 branch as well?
