v0.25.0

• Discord-flavored Markdown by @​liamwhite in kivikakk/comrak#421
  • Three new extensions and two render options are added:
    • extension.underline adds support for __underlined__ text.
    • extension.spoiler adds support for ||spoiler|| text.
    • extension.greentext adds support for image board-style >greentext, which isn't transformed into a blockquote.
    • render.ignore_setext disables parsing setext-style headings.
    • render.ignore_empty_links causes links with no text (like [](https://github.com/kivikakk/comrak/blob/HEAD/xyz)) to remain in the text as-is.
• nodes: add From impls for AstNode. by @​kivikakk in kivikakk/comrak#424
  • Back by popular demand: AstNode::from(NodeValue).
  • Also added is AstNode::from(Ast), if you have sourcepos.
• AST validation by @​yannham in kivikakk/comrak#425
  • The AST is validated when formatting a document as CommonMark in debug builds.
• Address autolink edge cases. by @​kivikakk in kivikakk/comrak#426
  • Autolinks had many edge cases where output differed from upstream cmark-gfm. These have been fixed by following upstream's parser design closely.
• shortcodes: capture all known aliases. by @​kivikakk in kivikakk/comrak#427
  • We didn't parse shortcodes containing numbers or +. We do now.
• Support both upstream CommonMark and GFM's differences in the base spec. by @​kivikakk in kivikakk/comrak#428
  • GFM modifies even base CommonMark output somewhat. We now support and validate against both.
• cm: count ol items from start of each list. by @​kivikakk in kivikakk/comrak#429
  • Ordered list item numbers are normalised on formatting back to CommonMark.
• arena_tree: panic if iterator invalidation causes trouble. by @​kivikakk in kivikakk/comrak#437
  • arena_tree would silently stop iteration when trying to proceed from a child that had lost its parent. It now panics instead, as the old behaviour is incorrect and impossible to notice.
• broken reflink callback updates & big cleanup. by @​kivikakk in kivikakk/comrak#438
  • The broken reference link callback has been moved into ParseOptions (which now takes a lifetime, meaning Options does too).
  • The callback now takes a struct containing both the normalised reference, and the original text, and the return value has changed from a 2-tuple to a struct for clarity.
  • parse_document_with_broken_link_callback has been marked deprecated.
• Inline sourcepos fixes. by @​kivikakk in kivikakk/comrak#439
  • Inline sourcepos was provided on a best-effort basis, but there are multiple correctness issues which can't be fixed without significant work.
  • Inline sourcepos is no longer reported in HTML output. It remains in the AST and in XML output, but it is not reliable. See the PR for details.
  • Link sourcepos is slightly better than it was when it spans multiple lines.
