ver. 2.0.0 (major version: new CommonMark/GFM engine)

• New engine (block parser, inline parser, HTML renderer) written after the parsing strategy of the CommonMark specification, still compatible from Delphi XE3
• mdCommonMark now runs on the new engine: CommonMark 0.31.2, all the 652 examples of the specification pass
• New dialect mdGFM: GitHub Flavored Markdown 0.29 (tables, task lists, strikethrough, extended autolinks, disallowed raw HTML), all the 24 examples pass
• New dialect mdGitHub, the new default (DefaultMarkdownDialect, CreateDialect without arguments): GFM + math + GitHub alerts + mermaid, as github.com
• mdDaringFireball and mdTxtMark keep the original engine with exactly the same output (checked by snapshot tests); the new dialects are appended to TMarkdownProcessorDialect, existing ordinals unchanged
• Optional syntax as individual flags (Config.Extensions): math, GitHub alerts, mermaid, subscript, superscript, insert, mark, smart typography, {#id} heading attributes, GitHub-style heading ids, wiki links
• Math formulas: KaTeX/MathJax markup (for viewers with JavaScript, e.g. WebView2) or codecogs images (Config.MathRendering, for HTMLViewer)
• Mermaid diagrams written as <pre class="mermaid"> for mermaid.js
• Read-only syntax tree IMarkdownNode with source line ranges: TMarkdownProcessor.Parse / Render
• New safe mode for the new engine: raw HTML omitted, javascript:/vbscript:/file:/data: links emptied
• Hooks kept: codeBlockEmitter receives every code block with its whole info string (mermaid included), specialLinkEmitter the [[...]] links
• Linear time on pathological inputs; no memory leaks
• New Delphi packages MarkdownProcessor (runtime) and dclMarkdownProcessor (design-time) for Delphi XE6 to 13, with build scripts
• New non-visual component TMarkdownToHTML (all the legacy extensions enabled by default) and new VCL demo Demo\MarkdownProcessorDemo
• Updated MarkDown Support Test.md: every feature of the GitHub dialect and of the legacy extensions
• New Setup for automatic installation, with optional MarkDownToHTML.exe (32 or 64 bit)
• MarkDownToHTML.exe: new -dialect:GitHub (default) and -dialect:GFM; executables built in Cmd\Win32 and Cmd\Win64
• New DUnitX test project (Win32 and Win64): official CommonMark and GFM examples, math, alerts, extensions, safe mode, hooks, syntax tree, performance; results in Tests/CONFORMANCE.md
• Breaking changes for mdCommonMark (tables and strikethrough need GFM/GitHub, non-standard syntax off by default, new math markup, raw HTML omitted in safe mode): see docs/MIGRATION.md

• fixed tables: inline constructs no longer span cells
• updated Markdown Support Test.md file
• fixed Allow Unsafe mode

11 Jun 2026: ver. 1.4.0

• Added "-unsafe" command line option to MarkDownToHTML.exe (safe mode is the default)
• Fixed safe mode: unsafe HTML elements (script, iframe, object, applet, frame...) are now correctly escaped
• Math formulas: replaced the deprecated Google Chart API with the CodeCogs LaTeX renderer
• Math formulas: added support for centered formula blocks using the $$...$$ syntax
• Improved tables support
• TUtils.codeEncode now encodes spaces as %20
• Aligned with upstream FPC-markdown by Miguel A. Risco-Castillo

• Added support for Delphi 13
• Added command line utility MarkDownToHTML.exe

• Fixed const parameters
