BYOND 4.0 Version 451.1033 Release Notes

In some games, an unexpected situation was occurring in which the client was being told about objects before it knew anything about the map, causing a crash. (Kiohstuff)

Demos and libraries that are packaged incorrectly so that they do not launch a .dme file on opening, should now open the directory instead of doing nothing. (Superbike32)

Verb descriptions with a double \n caused Dream Seeker to enter an infinite loop. (Mobius Evalon)

Features

If the pager's hub-address setting (File->Preferences->Advanced) is overriden and the specified address is unreachable, the default address (currently hub.byond.com:6001) will be attempted. If that is successful, the hub-address will be set to default for subsequent attempts.

The new command ".screenshot auto", like the regular ".screenshot" command, will save a screenshot of the current map, but it does not prompt for a filename. The default skin has been updated so in the menu you will now see a "Quick screenshot" command with the F2 shortchut, and "Save screenshot as..." with a Shift+F2 shortcut which follows the old behavior.
Screenshots saved in the quick way will always be in a .png format and are saved to the user's BYOND data directory under BYOND/screenshots. The filename is in this format:
Game name YYYY-MM-DD hhmmss.png
The name of the file is partly determined by the world.name value (which appears in the user's titlebar). After the file is saved, a message will be sent to the skin's default output control.
