THIS IS ON THE MASTER BRANCH. The Master branch will be Python 3.0 from now on. While Python 2.7 support will not be deliberately broken, all efforts should now focus on Python 3.0 compatibility. I can see a lot of work has been done. There's more to do. I've bumped the version number of everything I came across to the next major number for Python 3.0 compatibility indication. Thanks everyone. I hope to update here at least once a week until we have a stable 7.0 release for calibre 5.0

# 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 Added Python 3 compatibility for calibre 5.0
