Bumps mjml from 4.15.0 to 5.0.0.

Release notes

Sourced from mjml's releases.

v5.0.0

Upgrade Guide

These are the changes users need to actively consider when upgrading to MJML 5.x.x from MJML 4.x (and early MJML 5 alphas):

Highlights

  • Replaced legacy html-minifier and js-beautify with htmlnano + cssnano. [breaking change]
  • Added templating syntax sanitization (runs before PostCSS and is restored afterwards)
  • Safer, stricter handling of mj-include and ignoreIncludes [breaking change]
  • Restructured outer HTML: the <body> tag is now driven by mj-body, not the global skeleton. [breaking change]
  • mjml-browser build/minification pipeline updated
  • Better attribute consistency across components (including more flexible border-radius). [breaking change]
  • Migration helper removed [breaking change]
  • Updated toolchain: Node 20/22/24 in CI. Removed Node 16/18 [breaking change]

HTML/CSS minification & formatting

What changed

  • HTML minification now uses htmlnano instead of html-minifier.
  • CSS minification now uses cssnano presets wired via mjml-core.
  • Minification options can be added via .mjmlconfig.js

Impact [potential breaking changes]

  • Generated HTML is more aggressively minified. If you rely on exact formatting (e.g. diffing raw HTML, parsing by regex, or checking snapshots), you may see changes.
  • Some obscure html-minifier specific options used in custom tooling will no longer apply; options are now expressed as htmlnano/cssnano configs.
  • Template tags may error in PostCSS (see Template syntax handling and sanitization below)
  • Fixes this issue: mjmlio/mjml#2589

What to do

  • Review any automation that assumes pretty‑printed HTML (tests, diffs, CI snapshot comparisons).
  • If you previously passed minify/beautify flags or custom minifier options, re‑map them to the new htmlnano/cssnano config.

Notes

  • cssnano uses lite preset by default. Due to this issue: mjmlio/mjml#2919. default preset can be used if your fonts don’t contain numerals

More detail: (mjmlio/mjml#2858)

Template syntax handling and sanitization (PostCSS)

What changed

  • Template syntax (e.g. {{ }}) is now sanitized before PostCSS and with syntax restored post-processing.

Impact

  • A CssSyntaxError error will occur when applying CSS minification to files with some template syntax
  • Fixes this issue: mjmlio/mjml#2858
