That’s a standard heading for release notes or update information. To make it useful, you need to provide the content under those headings. For example:
Fixes:
* Resolved issue where app would crash on startup.
* Fixed bug causing incorrect data display in the settings menu.
* Corrected typographical error in the user agreement.
* Improved stability of the network connection.
What’s New:
* Added support for multiple user accounts.
* Implemented a new dark mode theme.
* Introduced a redesigned user interface.
* Enhanced performance with optimized code.
Provide the specifics for your “Fixes” and “What’s New” and I can help you further.
