v0.9.0 is the next major release.

Timetable: to be announced.

👉 Changelog

⚠️ Breaking Changes

• linkify: linkify is now a default plugin and uses linkify-it 6, with fuzzy matching off by default. Bare domains (www.example.com) and user:pass@ URLs are no longer linked. Use linkify({ fuzzyLink: true, urlAuth: true }) to restore the old behavior. With registerDefaultPlugins: false, autolinking is now off. Upgraded markdown-exit to 2.1 (#549)
• parser: removed the deprecated html option. Use registerDefaultPlugins: false and register html() yourself (#557)
• html: HTML attribute values are now decoded the way browsers decode attributes (e.g. ?a=1&copy=2 stays as written) (#511)
• utils: removed the decodeHTML re-export from comark/utils. textContent(node, { decodeUnicodeEntities }) is now textContent(node, { decodeHTML }), where you pass the decoder yourself (#511)
• @comark/html: @comark/html/render no longer re-exports all of comark/render. Import render, renderMarkdown, renderFrontmatter and resolveAttributes from comark/render or comark/utils. Output is always HTML, and components only get the html and comment handlers (#517)

Deprecations

• The linkify parser option is deprecated in favor of registerDefaultPlugins with linkify() (#549)
• The headings plugin is renamed to title-description, and its plugin name is now 'title-description' (#554)
• renderMath(), validateMath() and MathConfig.throwOnError will be removed in next rmajor (#510)
