Released version 4.1.1

🐛 Bug Fixes

• Message::setHtmlBody() – survives large inline data: URIs. A >500 kB base64 payload used to exhaust PCRE's backtrack limit and abort the whole send; the regex is now backtracking-free (#79)
• Message::setHtmlBody() – embeds images whose quoted src="…" or url('…') contains spaces, like "holiday photos/beach.jpg" (#97)
• Message::setHtmlBody() – embeds images whose quoted path contains parentheses, so the classic screenshot (1).png naming no longer silently breaks (#89)
• SendmailMailer – signs the full message so DKIM now covers Subject and To headers, closing a deliverability gap at Gmail, Outlook, and other strict providers (#99)
• MimePart – quotes address phrases containing special characters before MIME-encoding, producing spec-compliant headers even when names include commas, angle brackets, or quotes (#102)
• CssInliner – gracefully skips selectors the DOM engine can't evaluate; pseudo-classes and pseudo-elements like ::marker, :hover, :checked no longer break inlining
• CssInliner – tokenizer regex fixed for very long strings and invalid url() quote combinations that previously tripped the parser

Released version 4.1.0

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.
