To generate a changelog using Doxygen, you can follow these steps:

1. Make sure you have Doxygen installed on your system. If not, you can download and install it from the official website.
2. Create a configuration file for Doxygen (e.g., Doxyfile) in the root directory of your project. You can use the doxygen -g command to generate a template configuration file.
3. In the configuration file, set the GENERATE_CHANGES option to YES to enable changelog generation.
4. You can also specify other options related to changelog generation, such as CHANGE_LOGFILE, CHANGE_LOG_FORMAT, and EXCLUDE_SYMBOLS. Refer to the Doxygen documentation for more details on these options.
5. Run Doxygen with your configuration file as an argument. For example, you can run doxygen Doxyfile to generate the documentation, including the changelog.
6. Check the output directory specified in your configuration file for the generated changelog file.

By following these steps, you should be able to generate a changelog using Doxygen for your project.
