+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [1.0.0] - 2025-11-13
+
+### Added
+
+**Native Slack Block Support**
+- Lists now render using Slack's `rich_text_list` format with proper visual structure
+- Code blocks use `rich_text_preformatted` for improved syntax presentation
+- Blockquotes converted to `rich_text_quote` for cleaner formatting
+- Checkbox lists display with tick (✅) and empty box (☐) emoji indicators
+- Inline formatting (bold, italic, code) preserved within list items and quotes
+
+**Media and File Handling**
+- Video block support for embedding media content
+- Automatic file attachment detection based on file extensions
+- File links converted to native Slack file blocks
+
+**Table Rendering**
+- Native Slack table blocks for both Markdown and HTML tables
+- Column alignment support (left, centre, right)
+- Rich text formatting within table cells
+- HTML table parsing with graceful handling of malformed markup
+
+### Changed
+
+**Breaking Changes**
+- List rendering now outputs `rich_text` blocks instead of section blocks with markdown text
+- Blockquote rendering uses `rich_text_quote` for simple quotes (maintains backward compatibility for complex quotes)
+- Package renamed to `@mherod/mack` namespace
+- Build output relocated from `/build/src` to `/lib`
+
+**Build System**
+- Migrated from TypeScript compiler to tsup for faster builds
+- Dual-package support (CommonJS and ESM)
+
+### Fixed
+
+- Nested list rendering now processes all content correctly
+- Blockquotes support multiple content types (lists, code, headings)
+- Character escaping limited to Slack requirements (&, <, >)
+- Horizontal rule placement no longer affects adjacent list formatting
+- Markdown parsing API updated to current marked library standards
+
+### Technical Improvements
+
+- Comprehensive error handling with custom error classes
+- Input validation and URL verification
+- UTF-8 aware text truncation
+- Recursion depth protection
+- XML parsing security (XXE protection)
+- 223 test cases with comprehensive coverage
+- TypeScript strict mode compliance
