|
||
# Changelog
|
||
# 0.01 - Initial version
|
||
# 0.02 - Huffdic compressed books were not properly decrypted
|
||
# 0.03 - Wasn't checking MOBI header length
|
||
# 0.04 - Wasn't sanity checking size of data record
|
||
# 0.05 - It seems that the extra data flags take two bytes not four
|
||
# 0.06 - And that low bit does mean something after all :-)
|
||
# 0.07 - The extra data flags aren't present in MOBI header < 0xE8 in size
|
||
# 0.08 - ...and also not in Mobi header version < 6
|
||
# 0.09 - ...but they are there with Mobi header version 6, header size 0xE4!
|
||
# 0.10 - Outputs unencrypted files as-is, so that when run as a Calibre
|
||
# import filter it works when importing unencrypted files.
|
||
# Also now handles encrypted files that don't need a specific PID.
|
||
# 0.11 - use autoflushed stdout and proper return values
|
||
# 0.12 - Fix for problems with metadata import as Calibre plugin, report errors
|
||
# 0.13 - Formatting fixes: retabbed file, removed trailing whitespace
|
||
# and extra blank lines, converted CR/LF pairs at ends of each line,
|
||
# and other cosmetic fixes.
|
||
# 0.14 - Working out when the extra data flags are present has been problematic
|
||
# Versions 7 through 9 have tried to tweak the conditions, but have been
|
||
# only partially successful. Closer examination of lots of sample
|
||
# files reveals that a confusion has arisen because trailing data entries
|
||
# are not encrypted, but it turns out that the multibyte entries
|
||
# in utf8 file are encrypted. (Although neither kind gets compressed.)
|
||
# This knowledge leads to a simplification of the test for the
|
||
# trailing data byte flags - version 5 and higher AND header size >= 0xE4.
|
||
# 0.15 - Now outputs 'heartbeat', and is also quicker for long files.
|
||
# 0.16 - And reverts to 'done' not 'done.' at the end for unswindle compatibility.
|
||
# 0.17 - added modifications to support its use as an imported python module
|
||
# both inside calibre and also in other places (ie K4DeDRM tools)
|
||
# 0.17a- disabled the standalone plugin feature since a plugin can not import
|
||
# a plugin
|
||
# 0.18 - It seems that multibyte entries aren't encrypted in a v7 file...
|
||
# Removed the disabled Calibre plug-in code
|
||
# Permit use of 8-digit PIDs
|
||
# 0.19 - It seems that multibyte entries aren't encrypted in a v6 file either.
|
||
# 0.20 - Correction: It seems that multibyte entries are encrypted in a v6 file.
|
||
# 0.21 - Added support for multiple pids
|
||
# 0.22 - revised structure to hold MobiBook as a class to allow an extended interface
|
||
# 0.23 - fixed problem with older files with no EXTH section
|
||
# 0.24 - add support for type 1 encryption and 'TEXtREAd' books as well
|
||
# 0.25 - Fixed support for 'BOOKMOBI' type 1 encryption
|
||
# 0.26 - Now enables Text-To-Speech flag and sets clipping limit to 100%
|
||
# 0.27 - Correct pid metadata token generation to match that used by skindle (Thank You Bart!)
|
||
# 0.28 - slight additional changes to metadata token generation (None -> '')
|
||
# 0.29 - It seems that the ideas about when multibyte trailing characters were
|
||
# included in the encryption were wrong. They are for DOC compressed
|
||
# files, but they are not for HUFF/CDIC compress files!
|
||
# 0.30 - Modified interface slightly to work better with new calibre plugin style
|
||
# 0.31 - The multibyte encrytion info is true for version 7 files too.
|
||
# 0.32 - Added support for "Print Replica" Kindle ebooks
|
||
# 0.33 - Performance improvements for large files (concatenation)
|
||
# 0.34 - Performance improvements in decryption (libalfcrypto)
|
||
# 0.35 - add interface to get mobi_version
|
||
# 0.36 - fixed problem with TEXtREAd and getBookTitle interface
|
||
# 0.37 - Fixed double announcement for stand-alone operation
|
||
# 0.38 - Unicode used wherever possible, cope with absent alfcrypto
|
||
# 0.39 - Fixed problem with TEXtREAd and getBookType interface
|
||
# 0.40 - moved unicode_argv call inside main for Windows DeDRM compatibility
|
||
# 0.41 - Fixed potential unicode problem in command line calls
|
||
# 0.42 - Added GPL v3 licence. updated/removed some print statements
