EDIT: latest release of Imagick fails randomly to build for PHP 8.3 on alpine/amd64; waiting for them to tag a new release

From my understanding, the master branch of imagick works fine, but there hasn't been a release in ~2 years. There doesn't look to be any upstream activity regarding this issue and tagging a new release. At what point should we look for alternative solutions? Either by applying some workaround, or by getting rid of imagick from these images altogether? Not having php 8.3 support is a pretty big downside, especially since not all images are currently failing. What are your thoughts on this?

[le0m]

I was delaying this hoping that Imagick's devs would care to tag a new version, but as 3 months passed without any sign of them caring about this issue (namely, release a new version of the library like any normal library/project has done in the last 3/4 decades) it seems the time has come.

I'll implement a workaround in the coming days, sorry for the delay.

Don't worry about the delay! As you already said yourself, this is all due to the lack of a new version on imagick's side. But I am glad to see there is going to be a workaround, so that we can get php 8.3 versions of these images. Thanks a lot!
