You've reached a page on the Ren'Py wiki. Due to massive spam, the wiki hasn't been updated in over 5 years, and much of the information here is very out of date. We've kept it because some of it is of historic interest, but all the information relevant to modern versions of Ren'Py has been moved elsewhere.
Some places to look are:

This is a list of changes you may need to deal with when upgrading Ren'Py. Note that setting may cause many of these changes to be reverted, at the cost of losing access to recent features.
The default positions (left, right, center, truecenter, offscreenleft, and offscreenright) are now defined as ATL transforms. This means that showing an image at such a position will cause the position to be remembered. If you do not want this behavior, you need to redefine these positions, by adding the code:
define left = Position(xalign=0.0)
define center = Position(xalign=0.5)
define truecenter = Position(xalign=0.5, yalign=0.5)
define right = Position(xalign=1.0)
define offscreenleft = Position(xpos=0.0, xanchor=1.0)
define offscreenright = Position(xpos=1.0, xanchor=0.0)
To migrate your game from Ren'Py 6.9.2 or later, copy the directory containing your game into your projects directory. You can choose a projects directory by clicking "Options", "Projects Directory" in the Launcher. Please see the 6.9.2 release notes for information about migrating from older releases.
