🔗 PHPStan 2.3: Leap in performance, generics improvements, detecting unused variables, and more!

Since the release of PHPStan 2.3.0, users have experienced a staggering leap in performance with a reduction in analysis time for large codebases. For example, what previously took 60 seconds for WordPress now fits in just 8 seconds, thanks to the introduction of PHPStan Turbo. This version employs optimizations like C++ re-implementations and smart caching techniques, drastically improving analysis efficiency. Additionally, PHPStan now enhances generics support, allowing for precise type inference and fixing long-standing user issues with scalar generalization. Another notable change is the detection of unused variables, which helps catch potential bugs due to forgotten assignments. Overall, PHPStan 2.3.0 not only boosts performance but also enriches type-checking capabilities for developers, making their coding experience smoother and error-free.
