v22.0.0

Update Angular 22

It is recommended to stick with ngx-markdown v21.x.x if you are using Angular 21.

New features and enhancements

• Add support for Angular 22
• Migrate math rendering with KaTeX from katex/auto-render to marked-katex-extension fixing important rendering problems
• Deprecate MarkdownModule, which will be removed in the next major release in favour of provideMarkdown

⚠ Breaking changes

Fix for KaTeX math rendering

• KaTeX support now requires the optional marked-katex-extension package in addition to katex.
• Global KaTeX options can now be provided through the new katexOptions provider config in MarkdownModule.forRoot() or provideMarkdown() using the KATEX_OPTIONS injection token.
• Updated KaTeX installation instructions: include katex.min.css and do not rely on the old KaTeX auto-render script configuration.

Migration guidance

Remove the old KaTeX script entries and keep styles entry from angular.json:

"styles": [
+ "node_modules/katex/dist/katex.min.css"
],
"scripts": [
- "node_modules/katex/dist/katex.min.js",
- "node_modules/katex/dist/contrib/auto-render.min.js",
]

Install new extension:

npm install katex@^0.16.0 marked-katex-extension@^5.0.0 --save

If you previously used MarkdownService.render() with katex or katexOptions, move KaTeX configuration to the new provider-style setup and enable KaTeX at parse time instead.

📘 See the Math Rendering section in the README.md for more information.
