* The startup script (evennia.py) will now take your PYTHONPATH environmental variable into account when starting. This may resolve potential issues with Twisted on Windows with certain combinations of Python. * The INSTALL file still referred to startup.bat, which is now gone in favor of evennia.py. Thanks Ari!
