Announcing Psalm 4
I’m really happy to announce the release of Psalm 4. If you’re unfamiliar with Psalm, it’s a free & open-source static analysis tool that helps you identify problems in PHP.
It’s been almost two years since Psalm 3 was released, and a lot has happened. The PHP world has embraced static analysis in a big way – Psalm itself is over 15 times more popular. There's also a fantastic community of contributors ticketing bugs, submitting PRs and generally helping to make Psalm a really useful, well-tested tool.
PHP has changed too, with a big release – PHP 8 – coming out in five weeks’ time. I’ve spent the last few months making sure that Psalm 4 supports all the awesome new PHP 8 features.
Psalm 4 also has much better unused variable detection and it's faster, by default.
Give it a whirl, and let me know what you think!
