 # Changelog #
 
+## Version 3.13.3 ##
+
+🛠️ Bug fixes:
+
+* **Git report utility**: Fixed UnicodeDecodeError on Windows when commit messages contain non-ASCII characters
+  * The `guidata.utils.gitreport` module now explicitly uses UTF-8 encoding when reading Git command output
+  * Previously, on Windows systems with cp1252 default encoding, Git commit messages containing Unicode characters (emoji, accented characters, etc.) would cause a `UnicodeDecodeError`
+  * Fixed by adding `encoding="utf-8"` parameter to all `subprocess.check_output()` calls in `_extract_git_information()`
+  * This ensures proper decoding of Git output which is always UTF-8 encoded, regardless of the system's default encoding
