Release notes

Sourced from nette/di's releases.

Released version 3.2.6

A maintenance release laser-focused on type safety. Static analysis is now mandatory in CI, the codebase ships richer native and PHPDoc types, and the Tracy DI panel got a cleaner Latte rewrite. No behavioral changes – just a sturdier foundation for everything built on top.

• Native types – tightened parameter and return types across Compiler, ContainerLoader, ServiceDefinition and friends
• ContainerPanel – Tracy panel template rewritten with n:attributes for noticeably cleaner Latte syntax
• PHPStan-clean codebase – wide-ranging cleanup across DI internals so the whole tree passes strict analysis
• Richer PHPDoc – improved @param, @return and class descriptions across Compiler, Container, ContainerBuilder, Resolver, Helpers, definitions and extensions, giving IDEs and static analyzers far more to work with
• Better generic types – sharpened PHPDoc generics in autowiring, container builder, definitions and resolver
