Release notes

Fixed

• MD007: MkDocs flavor now enforces 4-space indentation (indent=4, style=fixed) as required by Python-Markdown; conflicting user config emits a warning and is overridden (#522)
• MD013: Reflow fix no longer dedents continuation paragraphs after code blocks inside admonitions in list items (#509)
• MD025: Auto-fix now cascades heading demotion to child headings, preserving the document’s heading hierarchy (#525)
• MD070: Fence collision detection expanded to ~50 language identifiers (Python, JS, Shell, Rust, Go, YAML, etc.) where triple backtick sequences commonly appear (#518)
• MD070: Auto-fix integration now works correctly in both CLI and LSP code action paths by including a complete Fix struct on warnings
• MD046: Removed redundant nested fence detection that produced false positives on Python code blocks containing embedded markdown
• LSP: Server now publishes empty diagnostics to invalidate client cache when switching to pull mode, preventing stale errors from persisting (#517)
