# Version
For information about NetHack versions, see Game history.
The #version extended command displays information about your version of NetHack. For a short one-line version information, you can press v.
Along with the version number, useful information about the set compile-time options and available windowing systems are shown. Certain things can be compiled in or out of the game; #version will show a list of all options compiled in. Within the options compiled in is a range of versions that save and bones files from the current version will be compatible with. Supported windowing systems such as tty and GUI are shown if available.

Example
Depending on your settings, using the version command might display something like the following:
