Microsoft adds Time Travel Debugging (TTD) to Windbg

Time Travel Debugging is now available in WinDbg Preview

We are excited to announce that Time Travel Debugging (TTD) features are now available in the latest version of WinDbg Preview. About a month ago, we released WinDbg Preview which provides great new debugging user experiences. We are now publicly launching a preview version of TTD for the first time and are looking forward to your feedback.[…]

As I hear, TTD has been used at Microsoft internally for years, just now getting this feature out to the public. Though they are not identical in implementation, GDB has had reverse execution for a while.
