+### Fixed
+- **Infinite Scroll Functionality**: Fixed missing `loadMoreIfNeeded()` function that was causing ReferenceError and preventing proper batch loading
+- **HTML Rendering Bug**: HTML code snippets now display as syntax-highlighted code instead of rendered HTML by properly encoding HTML entities
+- **Search Navigation**: Fixed sidebar navigation for unloaded snippets by adding `ensureSnippetLoadedAndScroll()` function
+- **Batch Loading Logic**: Implemented proper viewport-aware initial loading (max 3 batches) to prevent loading all snippets at page load
+
+### Added

+- **Enhanced Tag Detection**: Improved Docker workflow to fetch all tags before checkout for better reliability
+
+### Changed
