Use enable = ["ALL"] to explicitly enable all rules. * Fixed - MD013: Skip mkdocstrings autodoc blocks (::: module.Class with indented YAML options) during paragraph reflow (#396) - MD013: Implement trailing-word replacement for non-strict mode — reflow now correctly handles lines where the last word pushes past the limit - MD044: Skip proper name checking when link text is itself a URL (starts with http://, https://, or www.), matching markdownlint behavior (#395) ------------------------------------------------------------------- Tue Feb 10 05:51:52 UTC 2026 - Johannes Kastl - Update to version 0.1.17: * Fixed - Config: enable = [] is now correctly treated as "disable all rules" instead - of being silently ignored - MD013: Preserve MkDocs admonition markers (!!!, ???, ???+) during text - reflow instead of stripping them from continuation lines - MD033: Escape regex special characters in allowed-elements config values — - square brackets and other metacharacters were being interpreted as regex patterns - MD036: Only flag emphasis as heading-like when it forms a standalone paragraph - (surrounded by blank lines), matching markdownlint behavior * Changed - MD045: Made diagnostic-only — auto-fix removed because meaningful alt text - requires human judgment. Automated placeholders derived from filenames (e.g., - "User Profile image") are harmful for accessibility. The rule now reports missing - alt text without offering to fix it. - CI: Pass version in pre-commit dispatch payload * - Update to version 0.1.16: * Added - MD013: semantic-line-breaks reflow mode (preview) — breaks lines at semantic - boundaries using a cascading strategy: sentence boundaries first, then clause - punctuation (, ; : —), then English break-words (and, or, but, - which, that, because, etc.), then word wrap as fallback - (#388) * Fixed - MD013: Fix panic on multi-byte characters (smart quotes, em dashes) in - semantic line break sentence boundary detection - MD013: Preserve element adjacency during reflow — text directly adjacent - to shortcodes, code spans, or links (e.g., v{{< shortcode >}}) is no longer - split across lines - MD013: Use actual line length instead of URL-stripped length for line-length - checks — lines were incorrectly passing when long URLs inflated the real length - MD013: Preserve Quarto/Pandoc div markers (::: {.class}) during text reflow - instead of reflowing them into surrounding paragraphs - MD001: Track fixed heading level in check() for idempotent fixes — repeated - --fix runs no longer produce different output for multi-level heading violations - MD032: Idempotent fix for ordered non-1 list followed by unordered list - MD032: Use fix() method in proptest and allow convergence within 3 passes - MD062: Bail out when unmatched angle bracket masks closing paren, preventing - false positive warnings on valid link syntax - MD009: Strip all trailing Unicode whitespace in a single pass instead of - handling each whitespace character separately - GitHub Action: Support multiple space-separated file paths in path input - docs: Fix YAML typo, indentation, and --no-exclude descriptions - (thanks @JonathanWillitts in #385) - config: Handle markdownlint default key and boolean rule semantics in - .markdownlint.json compatibility - (#389) * Changed - reflow: Extract block boundary helpers to deduplicate paragraph detection logic -

MD011: Intelligent URL vs text detection in reversed links - Smarter classification of link components as URL or text - Reduces false positives in edge cases like (Generic)[link] - Correctly handles (http://url)[text] vs (text)[#anchor] - Improved heuristics for ambiguous single-word patterns - MD013: Preserve HTML blocks in list items during reflow - HTML blocks inside list items are now preserved during auto-fix - Prevents broken indentation and tag structure - Better handling of complex nested content * Changed - Architecture improvements for pre-computation pattern - LintContext now owns shared data structures - Rules consume pre-computed data instead of duplicating work - Consistent binary search APIs for range lookups - Foundation for future optimizations - Update to version 0.0.168: * Added - CLI: Support for Quarto (.qmd) and RMarkdown (.rmd/.Rmd) files - Added support for .qmd (Quarto), .rmd and .Rmd (RMarkdown) file extensions - Enables markdown linting for data science and scientific documentation workflows - Particularly useful for Jupyter-based publishing and reproducible research documents - LSP: will_save_wait_until for proper auto-fix on save - Implemented LSP textDocument/willSaveWaitUntil capability - Provides proper auto-fix on save support in compatible editors - More reliable than textDocument/didSave approach - Ensures fixes are applied before file is actually saved to disk - MD033: LSP Quick Fix to remove HTML tags while keeping content - New code action removes HTML opening and closing tags while preserving inner content - Helps convert inline HTML to plain text when needed - Available through editor Quick Fix menu (Ctrl+. or Cmd+.) * Fixed - MD013: Skip auto-fix for list items containing HTML tags - Prevents broken auto-fix when HTML tags are present in list items - HTML structure (indentation, tag hierarchy) is now preserved -
