All notable changes to MetonaEditor will be documented in this file.

[0.2.1] - 2026-07-25

Added

• Reference link/image resolution: Full support for [text][ref] and ![alt][ref] syntax with [ref]: url definitions.
• Right-click context menu: Built-in undo/redo/cut/copy/paste/selectAll with custom item support.
• RTL (Right-to-Left) CSS support: Full RTL layout for Arabic, Hebrew, Persian and other RTL languages.
• Japanese (ja) and Korean (ko) locales: Complete translations for all 60+ UI keys.
• Divider position persistence: Split-view divider ratio saved to localStorage and restored on reload.
• Regex search support: Toggle regex mode in search panel with .* button.
• Export HTML with embedded CSS: exportHTML now includes minimal CSS styles for standalone viewing.
• beforeChange / afterChange lifecycle hooks: Instance and global hooks that fire around content changes.
• copyAsMarkdown() / copyAsHTML() APIs: Copy editor content to clipboard as Markdown or rich HTML.
• New test suites: tests/index.test.ts (global API) and tests/styles.test.ts (CSS injection).
• 684 tests (up from 610), 9 test suites (up from 7).

Changed

• autoSave plugin refactored: Uses closure-based state per instance instead of this context, preventing state conflicts when the same plugin object is shared across multiple editors.
• Plugin install() now receives options as second argument for cleaner API.
• RTL locale detection improved: Now detects RTL by language prefix (e.g., ar-SA → RTL).

Fixed

• Reference link syntax [text][ref] now correctly resolves to links instead of raw text.
• Reference image syntax ![alt][ref] no longer produces empty src="".
• autoSave plugin state isolation when used across multiple editor instances.
• Footnote definitions no longer incorrectly consumed by reference definition parser.
