Psalm v6

[danog]

This is the first release of Psalm v6!

Users are encouraged to switch to Psalm v6 right away, as v5 is not supported anymore.

Also announcing Psalm's new support model: you can support Psalm development by requesting a support contract from Daniil Gentili, the only active maintainer of Psalm.

Support contracts can cover full integration of Psalm into existing codebases, support for Psalm issues and development of additional Psalm features.

See here » for info, pricing and contact information.

Main highlights of Psalm v6:

• PHP 8.4 support
• Amp v3 support
• PHP-Parser v5 support
• Fully overhauled dictionaries, for much more accurate and always up to date signatures for PHP and extension functions and methods, and much simpler PHP version upgrades.
• ignoreInternalFunctionFalseReturn and ignoreInternalFunctionNullReturn are now false by default: this means Psalm now warns when a false/null return type of a native function is not explicitly checked.
• Modernization of the codebase for higher performance.
• Many other bugfixes and performance improvements.

Plugin authors should consult the changelog for info about BC-breaking changes.

Awesome! Good job!

[robchett]

Great work, looking forward to updating ASAP.

TBH I've been looking at the issues and PRs in this repo quite a lot recently, but with the update in full swing I've been intimidated on where to start, as it wasn't clear what was/wasn't considered for v6.
Just know, help is available if you want it.

• Is CONTRIBUTING.md still relevant?
• Will you be considering using the help wanted / easy problems tags again on issues?
• Is there an official place to contact you?

[danog]

Happy to hear that; CONTRIBUTING is still relevant, and I just tagged #11208 with the Help wanted tag, since I currently don't have the funding to work on Simple Property Hooks (but probably might start work on them in the coming weeks for a client anyway, will see).

You may contact me on Telegram, that's really my preferred messaging app: @danogentili

Hello,

Would you consider adding a Sponsor button for your profile/this repo? (https://github.com/sponsors)

It would make it frictionless for us and probably other organizations to support your work :)

[staabm]

Just want to say 'thank you' for working on psalm.

Its awesome to see it moving again 💝
