 # Release Notes
 <!-- markdownlint-disable MD024 -->
 
+## Unreleased
+
+### Added
+
+- **Jekyll Extensions Support** (#114): Added support for dot notation in assign tags (e.g., `{% assign page.canonical_url = "/about/" %}`) when `JekyllExtensions` config flag is enabled. This allows Jekyll-compatible template syntax while maintaining Shopify Liquid compatibility by default.
+
+- **Auto-Escape Feature** (#111): Implemented automatic HTML escaping for template output with opt-in/opt-out support via the `safe` filter. Output is automatically escaped by default when auto-escape is enabled, and can be marked as safe using `{{ value | safe }}`. Thanks [@dop251](https://github.com/dop251)
+
+### Changed
+
+- **Modernized Build Tooling** (#115): Updated golangci-lint configuration to v2 format, reorganized Makefile with comprehensive targets, and added pre-commit hooks for automated code quality checks. All existing lint and format issues have been resolved.
+
+### Fixed
+
+- Fixed trailing whitespace issues in test files
+- Resolved all golangci-lint v2 compatibility issues
+
 ## 1.3.0 (2020-02-13)
