  title="...") are no longer flagged as incorrectly capitalized. Text content between
  tags continues to be checked as usual (#​443)

v0.1.24

Compare Source

Fixed

• MD013: GitHub Flavored Markdown alert markers (> [!NOTE], > [!WARNING], etc.)
  are now preserved as non-wrappable boundaries during blockquote reflow — previously
  the alert type was merged with the following content line, corrupting the alert block
• MD013: Reflow now wraps blockquote paragraphs (including lazy continuation lines)
  in fmt/check --fix, with deterministic style preservation and LSP manual reflow
  parity (#​437)
• MD013: Italic and bold paragraphs that exceed the configured line length are now
  reflowed correctly; previously only plain text paragraphs were wrapped
  (#​441)
• MD013: GFM task list checkboxes ([ ], [x], [X]) are now preserved as
  non-wrappable marker prefix during reflow, preventing - [ ] [long url](...) from
  being corrupted to - []\n [long url](...)
  (#​436)
• MD013: List continuation lines are now normalized to the canonical marker-length
  indent during reflow instead of inheriting any over-indentation from the source
  (#​439)
• MD013: Reflow no longer introduces double blank lines when an HTML block
  (e.g. <details>) captures a trailing blank line — previously this caused MD012
  violations in large documentation repos
• MD030: Byte offset computation for ordered list markers inside blockquotes was
  incorrect, causing fixes to insert spaces at the wrong position and be non-idempotent
• MD044: Names configured in names are no longer falsely flagged inside HTML
  attribute values when the name appears adjacent to underscores (e.g. test_image)
  (#​443)
• MD048: Fence-length disambiguation when converting between backtick and tilde
  styles now correctly handles blocks where an interior same-style sequence would
  otherwise close the outer block early under CommonMark rules; the 0–3 space indent
  limit is enforced for fence markers per CommonMark §4.5
• CLI: --flavor gfm, --flavor github, --flavor commonmark, --flavor qmd,
  --flavor rmd, and --flavor rmarkdown are now accepted (previously rejected by
  the argument parser despite being valid in config files)
  (#​440)
• stdin: Inline config directives (<!-- rumdl-disable-next-line -->,
  <!-- rumdl-disable --> / <!-- rumdl-enable -->, <!-- markdownlint-disable -->,
  etc.) are now respected when reading from stdin (rumdl check -); previously
  all such directives were silently ignored, causing false positives in editor
  integrations such as nvim-lint that pipe content via stdin
  (#​445)

v0.1.23

Compare Source

Added

• MD033: Relaxed fix mode that converts HTML tags with extra attributes (e.g. target, rel, width, height) by dropping non-essential attributes during conversion. Event handler attributes (on*) are never dropped. Enable via config.
  (#​397)

Fixed

• Fix mode: Rules depending on ctx.source_file (MD057, MD074) no longer silently skip validation during re-lint, preventing false "no issues found" results and exit code 0 when violations remained
  (#​435)
• Fix coordinator: Non-convergence now reports the conflicting rules, observed cycle path, and concrete remediation steps (unfixable/disable/config options)
• MD012: Blank line sequences adjacent to ATX or Setext headings are now skipped, preventing conflicts with MD022's lines-above/lines-below settings
  (#​429)
• MD063: Proper-name preservation now uses unicode-safe case-folding with title/sentence/all-caps handling and link text coverage
  (#​431)
• Import: Generated TOML output no longer has a trailing blank line
  (#​433)

Added

• Config: Per-directory configuration resolution — place .rumdl.toml in
  subdirectories to override settings for specific paths
• MD075: New rule to detect orphaned table rows and headerless pipe content
  (#​426)

Fixed

  YAML when checking for title field
  (#​427, thanks @​Nathan-Furnal)
• MD054: Match warning message with rule configuration option
  (thanks @​eread in #​421)

  canonical format and accept snake_case, kebab-case, and uppercase variants.
  Affected rules: MD003, MD046, MD048, MD049, MD050, MD055, MD060, MD063
  (#​428, thanks @​eread)
• Config: Fix root detection and cross-file rule resolution for
  per-directory configs
