+## Major Improvements
+
+### Code Quality & Reliability
+* Added comprehensive error handling to all scraping functions with informative error messages
+* Implemented input validation across all functions
+* Added graceful handling of NULL inputs and empty results
+* Scraping functions now provide detailed warnings when extraction fails
+
+### Documentation
+* Added complete roxygen2 documentation to all functions
+* Improved function descriptions with parameter details and return values
+* Added usage examples and implementation details
+* All internal functions now properly documented with @keywords internal
+
+### Testing
+* Set up testthat testing framework
+* Added unit tests for all extraction functions
+* Added data validation tests to ensure data quality
+* Added input validation tests for main scraping function
+* Created test suite for edge cases and error handling
+
+### GitHub Actions & Automation
+* Updated all GitHub Actions to latest versions (checkout@v4, cache@v3, setup-r@v2)
+* Improved workflow to skip commits when no new data is available
+* Enhanced commit messages to show number of new episodes added
+* Added helper script to count new episodes for informative commit messages
+
+### Package Infrastructure
+* Updated .gitignore with standard R package exclusions
+* Added NEWS.md for tracking package changes
+* Updated DESCRIPTION with testthat dependency
+* Improved RoxygenNote to version 7.2.3
+
+### Data Quality
+* Maintained existing speaker name normalization
+* Preserved incremental scraping functionality
+* Kept multi-format output support (RDS, RDA, Parquet)
+
+## Bug Fixes
+* Fixed potential crashes from NULL HTML responses
+* Improved handling of malformed or changed website structure
+* Better error messages for debugging scraping failures
