Please provide a build of the current master (pre-alpha / weekly build / upcoming version)
I suggest building the current master regularly and providing it as "PHP unstable", "PHP nightly", "PHP next" or similar.
Being able to use the upcoming version of PHP with the ease and shareability of 3v4l would be great.
Both for me personally but also for the community. Edge cases of new features and reproducible crashes could be discovered earlier.
To avoid confusion and potential mess, another checkbox could be added along with "eol versions".
