Release Notes

fsprojects/FSharp.Formatting (fsdocs-tool)

v22.2.0

Changed

• Bump Suave from 2.6.2 to 3.4.6. The fsdocs watch websocket handling was migrated to Suave 3's Task-based socket API, the removed Suave.Logging usage was dropped, and clients that disconnect without a close handshake are now deregistered so a live-reload broadcast can no longer crash the watch server with an ObjectDisposedException.
• During fsdocs watch, the logo now links to the locally hosted site root (e.g. http://localhost:8901/) instead of the production URL, even when <FsDocsLogoLink> is set. Release builds are unaffected.
• The fsdocs watch console no longer logs websocket connection chatter ("New websocket connection", "WebSocket disconnected", ...) on every page reload.

Removed

• Remove docs/Dockerfile (used for mybinder.org Binder integration) and mybinder badge links from documentation pages. The Binder integration relied on a deprecated .NET 7 SDK image and a deprecated Microsoft.dotnet-interactive version; mybinder.org support is discontinued.
• Remove .ipynb (Jupyter Notebook) "run in notebook" badge links from all documentation pages and delete docs/img/badge-notebook.svg. The links linked to .ipynb outputs generated by fsdocs, but .NET Interactive (which powered those notebooks) is deprecated and has no current replacement. The .ipynb output format itself is unchanged.

v22.1.0

Changed

• Improve ProjectCracker project resolution to handle *.slnf and *.slnx. [#​1213](https://github.com/fsproject
  s/FSharp.Formatting/pull/1213)

v22.0.1

Changed

• Compile Regex instances to module-level singletons (with RegexOptions.Compiled) in PageContentList, HtmlFormatting, Formatting, Menu, and LlmsTxt. Previously a new, uncompiled Regex was constructed on every call (once per page heading, once per HTML page, once per menu item, once per llms.txt entry), incurring repeated JIT overhead. The patterns are now compiled once at module load and reused across all calls.
• Replace deprecated System.Net.WebClient with System.Net.Http.HttpClient in the image downloader used by --saveimages. Removes the #nowarn "44" suppression.
• Bump Newtonsoft.Json transitive-dependency pin from 13.0.3 to 13.0.4.
• Bump System.Memory transitive-dependency pin from 4.5.5 to 4.6.3.0
• Remove stale VersionOverride="43.12.201" on the FSharp.Compiler.Service reference in FSharp.Formatting.Markdown.fsproj; the package now uses the central pin (43.12.202) from Directory.Packages.props, eliminating the NU1605 build warning.
• Replace Enumerable.Cast<XAttribute> (LINQ) with Seq.cast<XAttribute> (idiomatic F#) in MarkdownUtils.fs, removing the open System.Linq import.

Fixed

• Fix Markdown.ToMd serialising table data rows with a hardcoded \n line separator instead of the configured newline. On Windows (where Environment.NewLine is \r\n) this produced mixed line endings in the output. Each data row is now yielded separately, consistent with how every other paragraph type works. The trailing blank line after a table was also emitting a literal "\n" string instead of the standard "" empty-line sentinel.
• Fix Markdown.ToFsx hardcoding a \n newline in the (* output: ...) comment wrapper around code-cell outputs. The configured ctx.Newline is now used, ensuring consistent line endings on Windows.
• Fix Markdown.ToMd silently dropping YAML frontmatter when serialising a parsed MarkdownDocument back to Markdown text. Frontmatter is now preserved with its --- delimiters.
• Fix Markdown.ToMd converting tight lists (no blank lines between items) into loose lists by emitting a blank line after every item. Tight lists now round-trip correctly without inter-item blank lines.
• Fix Markdown.ToMd serialising HardLineBreak as a bare newline instead of two trailing spaces + newline. The correct CommonMark representation " \n" is now emitted, so hard line breaks survive a round-trip through ToMd.
• Fix Markdown.ToMd serialising HorizontalRule as 23 hyphens regardless of the character used in the source. It now emits exactly three characters matching the parsed character (---, ***, or ___), giving faithful round-trips.
• Remove stray printfn debug output emitted to stdout when Markdown.ToMd encountered an unrecognised paragraph type.
• Fix Markdown.ToLatex producing invalid LaTeX output for level-6 (and deeper) headings. Previously the LaTeX command was an empty string, resulting in bare {content} without a command prefix. Headings at level 6+ are now serialised as \subparagraph{...}, which is the deepest sectioning command available in LaTeX.
• Fix Markdown.ToMd silently dropping EmbedParagraphs nodes: the serialiser now delegates to the node's Render() method and formats the resulting paragraphs, consistent with the HTML and LaTeX back-ends.
• Fix Markdown.ToMd dropping link titles in DirectLink and DirectImage spans. Links with a title attribute (e.g. [text](url "title")) now round-trip correctly; without this fix the title was silently discarded on serialisation.
• Fix Markdown.ToMd serialising inline code spans that contain backtick characters. Previously, InlineCode was always wrapped in single backticks, producing syntactically incorrect Markdown when the code body contained backticks. Now the serialiser selects the shortest backtick fence that does not collide with the body content (e.g. a double-backtick fence for bodies containing single backticks, triple for double, etc.), matching the CommonMark spec.
• Fix Markdown.ToMd multi-paragraph blockquote round-trip. The old code emitted a bare blank line between inner paragraphs, which CommonMark parses as closing the blockquote, resulting in multiple separate blockquotes on re-parse. Paragraph separators inside a blockquote are now emitted as > (an empty blockquote continuation line) so the round-trip preserves a single QuotedBlock.
• Fix Markdown.ToMd serialising unresolved indirect links as [body](key) (treating the reference key as a URL) instead of the correct [body][key] form. Unresolved indirect links are now preserved in their original indirect-reference form, consistent with how unresolved indirect images are handled.
• Fix Markdown.ToMd silently dropping AnchorLink spans. Named anchors (used by the API documentation generator to create in-page navigation targets) are now serialised as <a name="..."></a> inline HTML, so they survive a round-trip and remain functional when the output is later converted to HTML.

Added

• Introduce --panel-background and --panel-border CSS custom properties in fsdocs-default.css. These decouple panel/component colours (copy-code button, blockquotes, sidebar, page menu, dialogs, tooltips, API tables) from --header-background/--header-border. Both variables default to the header values, so existing themes are unaffected; themes that need a different colour for content panels can now override --panel-background and --panel-border independently. #​1156
• Add tests for Markdown.ToFsx (direct serialisation to F# script format), which previously had no unit test coverage.
• Add tests for Markdown.ToPynb (direct serialisation to Jupyter notebook format), which previously had no unit test coverage.
• Add round-trip tests for HardLineBreak and HorizontalRule character preservation in Markdown.ToMd.
• Add direct unit tests for Markdown.ToLatex, which previously had no unit test coverage. Tests cover headings (all six levels), inline formatting (bold, italic, inline code), links, images with captions, lists (ordered and unordered), code blocks, blockquotes, tables with bold headers, horizontal rules, LaTeX special character escaping, inline math, and display math.

v22.0.0

Fixed

• Fix spurious 'fsi' is not defined error during literate script type-checking when scripts use fsi.AddPrinter or related APIs. The FSharp.Compiler.Interactive.Settings.dll reference is now explicitly added to the type-checker options. #​1139
• Fix literate script comment parser prematurely closing (** blocks when the markdown text contained nested (*** ... ***) references (e.g. in backtick-quoted command examples), causing subsequent content to be silently dropped from HTML output.
• Add missing [<Test>] attribute on Can include-output-and-it test so it is executed by the test runner.
• Add regression test confirming that types whose name matches their enclosing namespace are correctly included in generated API docs. #​944
• Fix crash (failwith "tbd - IndirectImage") when Markdown.ToMd is called on a document containing reference-style images with bracket syntax. The indirect image is now serialised as ![alt](url) when the reference is resolved, or in bracket notation when it is not. #​1094
• Fix Markdown.ToMd serialising italic spans with asterisks incorrectly as bold spans. #​1102
• Fix Markdown.ToMd serialising ordered list items with incorrect numbering and formatting. #​1102
• Fix Markdown.ToMd not preserving indented code blocks: bare code output was re-parsed as a paragraph. Indented code blocks are now serialised as fenced code blocks, which round-trip correctly.
• Fix Markdown.ToMd serialising *emphasis* (italic) spans as **...** (bold) instead of *...*. #​1102
• Fix Markdown.ToMd serialising ordered list items with 0-based numbering and no period (e.g. 0 first) instead of 1-based with a period (e.g. 1. first). #​1102
• Fix HtmlElement SVG serialisation: LinearGradient now renders as <linearGradient> and RadialGradient now renders as <radialGradient> — both previously emitted the invalid tag <radient>.

Changed

• fsdocs build now pre-computes the navigation menu structure (filter/group/sort) once per build rather than once per output page, reducing work from O(n²) to O(n) for sites with n pages. The filesystem check for custom menu templates is also cached per build. #​1129
