| HISTORY of the LZMA SDK | |
| ----------------------- | |
| 16.04 2016-10-04 | |
| ------------------------- | |
| - The bug was fixed in DllSecur.c. | |
| 16.03 2016-09-28 | |
| ------------------------- | |
| - SFX modules now use some protection against DLL preloading attack. | |
| - Some bugs in 7z code were fixed. | |
| 16.02 2016-05-21 | |
| ------------------------- | |
| - The BUG in 16.00 - 16.01 was fixed: | |
| Split Handler (SplitHandler.cpp) returned incorrect | |
| total size value (kpidSize) for split archives. | |
| 16.01 2016-05-19 | |
| ------------------------- | |
| - Some internal changes to reduce the number of compiler warnings. | |
| 16.00 2016-05-10 | |
| ------------------------- | |
| - Some bugs were fixed. | |
| 15.12 2015-11-19 | |
| ------------------------- | |
| - The BUG in C version of 7z decoder was fixed: | |
| 7zDec.c : SzDecodeLzma2() | |
| 7z decoder could mistakenly report about decoding error for some 7z archives | |
| that use LZMA2 compression method. | |
| The probability to get that mistaken decoding error report was about | |
| one error per 16384 solid blocks for solid blocks larger than 16 KB (compressed size). | |
| - The BUG (in 9.26-15.11) in C version of 7z decoder was fixed: | |
| 7zArcIn.c : SzReadHeader2() | |
| 7z decoder worked incorrectly for 7z archives that contain | |
| empty solid blocks, that can be placed to 7z archive, if some file is | |
| unavailable for reading during archive creation. | |
| 15.09 beta 2015-10-16 | |
| ------------------------- | |
| - The BUG in LZMA / LZMA2 encoding code was fixed. | |
| The BUG in LzFind.c::MatchFinder_ReadBlock() function. | |
| If input data size is larger than (4 GiB - dictionary_size), | |
| the following code worked incorrectly: | |
| - LZMA : LzmaEnc_MemEncode(), LzmaEncode() : LZMA encoding functions | |
| for compressing from memory to memory. | |
| That BUG is not related to LZMA encoder version that works via streams. | |
| - LZMA2 : multi-threaded version of LZMA2 encoder worked incorrectly, if | |
| default value of chunk size (CLzma2EncProps::blockSize) is changed | |
| to value larger than (4 GiB - dictionary_size). | |
| 9.38 beta 2015-01-03 | |
| ------------------------- | |
| - The BUG in 9.31-9.37 was fixed: | |
| IArchiveGetRawProps interface was disabled for 7z archives. | |
| - The BUG in 9.26-9.36 was fixed: | |
| Some code in CPP\7zip\Archive\7z\ worked correctly only under Windows. | |
| 9.36 beta 2014-12-26 | |
| ------------------------- | |
| - The BUG in command line version was fixed: | |
| 7-Zip created temporary archive in current folder during update archive | |
| operation, if -w{Path} switch was not specified. | |
| The fixed 7-Zip creates temporary archive in folder that contains updated archive. | |
| - The BUG in 9.33-9.35 was fixed: | |
| 7-Zip silently ignored file reading errors during 7z or gz archive creation, | |
| and the created archive contained only part of file that was read before error. | |
| The fixed 7-Zip stops archive creation and it reports about error. | |
| 9.35 beta 2014-12-07 | |
| ------------------------- | |
