+## [1.3.0] - 2025-08-23
+
+### Changed
+- **Standardized Default Absence Codes:** Replaced the initial Spanish absence codes (e.g., "LICENCIA MÉDICA") with a set of universal, English-language defaults (e.g., "Sick Leave", "Vacation"). This provides a more consistent out-of-the-box experience for new users.
+- Refactored the data initialization script (`init_data.py`) by extracting the default codes into a constant, improving readability and maintainability.
+
+### Removed
+- Removed the unused `ABSENCE_CODES` list from the `config.py` file. This eliminates redundancy and establishes the database as the single source of truth for absence codes.
