# History:
|
|
# 0.1 Initial release
|
|
# 0.2 Added support for generating PID for iPhone (thanks to mbp)
|
|
# 0.3 changed to autoflush stdout, fixed return code usage
|
|
# 0.3 updated for unicode
|
|
# 0.4 Added support for serial numbers starting with '9', fixed unicode bugs.
|
|
# 0.5 moved unicode_argv call inside main for Windows DeDRM compatibility
|
|
# 1.0 Python 3 for calibre 5.0
