html_to_markdown_rust changelog

0.3.0 #

Added convertHtml, a unified conversion API that can return converted text, a typed document tree, span-aware tables, rich metadata, inline images, and non-fatal ProcessingWarning values in one pass.
Added Markdown, Djot, and plain-text output selection plus base-URL resolution, reference links, CSS selector exclusion, compact tables, and other Rust 3.15.1 conversion options.
Added typed document nodes, span-aware table models, and models for UTF-8 byte-range annotations. The Rust 3.15.1 structure collector currently leaves annotations empty and can include inline Markdown in node text. Table collection requires includeDocumentStructure: true; plain-text input can take a fast path that omits the document tree in any output format.
Corrected structured table coordinates across row-spanning cells returned by Rust 3.15.1, consistently in document nodes and extracted tables.
Expanded metadata with author, canonical and base URLs, language, text direction, Open Graph, Twitter Card, classified links and images, custom meta tags, and typed structured-data entries.
Preserved htmlToMarkdown, htmlToMarkdownWithMetadata, and htmlToMarkdownWithInlineImages for existing callers.

Updated the Rust converter from html-to-markdown-rs 2.25.1 to 3.15.1 and the native-assets Rust toolchain to 1.99.0.
Updated Native Assets to hooks 2.2.0, code_assets 2.1.0, and native_toolchain_rust 1.0.7; refreshed Dart and FFI tooling dependencies.
Raised the minimum Dart SDK to 3.13.0 and pinned development Flutter to 3.47.5 with FVM.
Kept the three public conversion functions and adapted options, metadata, and inline-image results to the unified Rust 3.x conversion API.
Fixed UTF-8 input lengths and released all FFI allocations on success and failure, including HTML buffers and embedded-NUL input.
Fixed JSON serialization of conversion options and enabled skipLinks while retaining formatted link text.
Reworked the README with installation, examples, use cases, and reproducible benchmarks.

Rust 3.x can change Markdown formatting; whitespace-only input now produces an empty string. Test output snapshots before upgrading.
Legacy script/style/comment/hidden-element preprocessing switches are deprecated because Rust 3.x no longer exposes those controls. The legacy NewlineStyle.preserve and HighlightStyle.asterisk values map to trailing spaces and bold highlighting respectively.
MetadataConfig.maxStructuredDataSize accepts 0 through 1,000,000 bytes (the upstream safety ceiling), defaults to 1,000,000, and rejects larger values. Disabled metadata fields are filtered from the result.
SVG dimensions remain optional; automatic dimension inference supports raster images.
