- added MakeYword - wrap obsolete IDA API functions too, so that old scripts continue to work - added debugger trace related functions in idc.py BUGFIX: IDAPython would fail with a cryptic error message if there was no free space on the current disk BUGFIX: site-packages directory was missing from sys.path BUGFIX: functions for working with additional lines (LineA/LineB etc) were broken BUGFIX: GetFixup* functions from idc.py were broken BUGFIX: IDA could not start if another python27.dll was present in PATH and importing site.py for that Python installation failed BUGFIX: SaveBase() was broken BUGFIX: IDAPython would fail with a cryptic error message if there was no free space on the current disk BUGFIX: IDAPython: site-packages directory was missing from sys.path BUGFIX: IDAPython: functions for working with additional lines (LineA/LineB etc) were broken BUGFIX: IDAPython: GetFixup* functions from idc.py were broken BUGFIX: IDAPython: IDA could not start if another python27.dll was present in PATH and importing site.py for that Python installation failed BUGFIX: IDAPython: SaveBase() was broken BUGFIX: Dbg/Idp hooks automatically unhook when hook object is not referenced anymore note: these patches are already applied in IDAPython that comes with IDA Pro 6.4
