Composer resolves to highest versions (except phpunit)

@TomHAnderson, I see that this hasn't moved in a while. I'm likely to need it sooner or later. Is there anything I can do to help things along?

[edit: I've followed the trail a little further, and I see that you're running into some of the same interlocking Laminas dependency changes that have been causing trouble on my end as well... we may just have to keep waiting for some things, but if you need Laminas-related help to make progress, feel free to call on me and I'll do what I can as time permits.]

@demiankatz We cannot provide support for ORM 3 in a new minor release. The reason is stated in doctrine/DoctrineModule#833. We need to switch DoctrineModule from doctrine/cache to psr/cache, which results in a BC break. I have, however, prioritized support for PHP 8.4, which will be available with 6.3.0, as soon as laminas/laminas-serializer#73 is merged and released.

Thanks, @driehle, I definitely understand that a major release will be needed for ORM 3. I appreciate the incremental progress on minor releases in the meantime, but I'm also willing to help out as needed to get to the next major version (though I also realize that there's some uncertainty about the future of Laminas modules in general; maybe what will ultimately be needed is something of an entirely different shape... I'm still watching and waiting to see how everything ends up developing).
