# 2.6 - Better handling of non-K4PC/Mac ebooks
# 2.7 - Better trailing bytes handling in mobidedrm
# 2.8 - Moved parsing of kindle.info files to mac & pc util files.
# 3.1 - Updated for new calibre interface. Now __init__ in plugin.
# 3.5 - Now support Kindle for PC/Mac 1.6
# 3.6 - Even better trailing bytes handling in mobidedrm
# 3.7 - Add support for Amazon Print Replica ebooks.
# 3.8 - Improved Topaz support
# 4.1 - Improved Topaz support and faster decryption with alfcrypto
# 4.2 - Added support for Amazon's KF8 format ebooks
# 4.4 - Linux calls to Wine added, and improved configuration dialog
# 4.5 - Linux works again without Wine. Some Mac key file search changes
# 4.6 - First attempt to handle unicode properly
# 4.7 - Added timing reports, and changed search for Mac key files
# 4.8 - Much better unicode handling, matching the updated inept and ignoble scripts
# - Moved back into plugin, __init__ in plugin now only contains plugin code.
