This release introduces CssInliner – a brand-new component that brings CSS-to-inline-style conversion directly into Nette Mail. The minimum PHP version has been raised to 8.2, and static analysis is now a mandatory part of the build pipeline.

• Minimum PHP version raised from 8.0 to 8.2 – time to upgrade if you haven't already

• Improved PHPDoc types and descriptions for better IDE support and static analysis accuracy

• CssInliner – converts <style> rules into inline style attributes, making your HTML emails render consistently across email clients. Features a single-regex tokenizer, full CSS nesting support, Dom\HTMLDocument selector matching (PHP 8.4+), and automatic Outlook-compatible HTML attribute generation (bgcolor, width, align, etc.). <style> tags are preserved so @media queries keep working.
