MarkNLD This raises an important question: what would be the optimal update frequency for PHP releases?
Monthly is best. Every 1-2 months is still tolerable, since in real-world setups dedicated shared hosting servers can run for months without a reboot, so updates won’t always apply right away even if they’re pushed promptly.
What matters way more is keeping the actual software- WordPress, plugins, themes, or whatever CMS/app you’re running - updated. That’s the step most folks skip.
