@frederikbosch Every year we see each other in these type of PR's and we previously discussed it and I understand your position.

I wonder I we could maybe find a middle ground where we say, we tag support for Money PHP as soon as we have Release Candidate X? I would be happy to do the work every year.

@ruudk and so we meet again. How about #818? We add a specific job to CI for early versions (and php-src main when there is no new version?) that ignores platform reqs and allows to fail?

[frederikbosch]

But, once we can add || ~8.5.0, I am happy to merge that, fully support the version and tag it, even if the new PHP version is not a stable release yet.

@ruudk With new setup we always test dev version of PHP, but allow it to fail (|| true). This way we could see early on if there are problems with a new version. Once we can add || new-version to composer.json we can add full support to the version and tag a new release. Hopefully this is an improvement over what we had before.

@ruudk And v4.8.0 has just been tagged, with support for PHP8.5. Thanks for bringing it up and suggestion to improve the setup.

@frederikbosch Sounds like a great workflow going forward! This makes me really happy. 🎉 Thanks
