HISTORY of the LZMA SDK
|
||
-----------------------
|
||
|
||
19.00 2019-02-21
|
||
-------------------------
|
||
- Encryption strength for 7z archives was increased:
|
||
the size of random initialization vector was increased from 64-bit to 128-bit,
|
||
and the pseudo-random number generator was improved.
|
||
- The bug in 7zIn.c code was fixed.
|
||
|
||
|
||
18.06 2018-12-30
|
||
-------------------------
|
||
- The speed for LZMA/LZMA2 compressing was increased by 3-10%,
|
||
and there are minor changes in compression ratio.
|
||
- Some bugs were fixed.
|
||
- The bug in 7-Zip 18.02-18.05 was fixed:
|
||
There was memory leak in multithreading xz decoder - XzDecMt_Decode(),
|
||
if xz stream contains only one block.
|
||
- The changes for MSVS compiler makefiles:
|
||
- the makefiles now use "PLATFORM" macroname with values (x64, x86, arm64)
|
||
instead of "CPU" macroname with values (AMD64, ARM64).
|
||
- the makefiles by default now use static version of the run-time library.
|
||
|
||
|
||
18.05 2018-04-30
|
||
-------------------------
|
||
- The speed for LZMA/LZMA2 compressing was increased
|
||
by 8% for fastest/fast compression levels and
|
||
by 3% for normal/maximum compression levels.
|
||
- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in
|
||
Windows 10 because of some BUG with "Large Pages" in Windows 10.
|
||
Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).
|
||
- The BUG was fixed in Lzma2Enc.c
|
||
Lzma2Enc_Encode2() function worked incorretly,
|
||
if (inStream == NULL) and the number of block threads is more than 1.
|
||
|
||
|
||
18.03 beta 2018-03-04
|
||
-------------------------
|
||
- Asm\x86\LzmaDecOpt.asm: new optimized LZMA decoder written in asm
|
||
for x64 with about 30% higher speed than main version of LZMA decoder written in C.
|
||
- The speed for single-thread LZMA/LZMA2 decoder written in C was increased by 3%.
|
||
- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,
|
||
if there are multiple independent data chunks in LZMA2 stream.
|
||
- 7-Zip now can use multi-threading for xz decoding,
|
||
if there are multiple blocks in xz stream.
|
||
|
||
|
||
18.01 2019-01-28
|
||
-------------------------
|
||
- The BUG in 17.01 - 18.00 beta was fixed:
|
||
XzDec.c : random block unpacking and XzUnpacker_IsBlockFinished()
|
||
didn't work correctly for xz archives without checksum (CRC).
|
||
|
||
|
||
18.00 beta 2019-01-10
|
||
-------------------------
|
||
- The BUG in xz encoder was fixed:
|
||
There was memory leak of 16 KB for each file compressed with
|
||
xz compression method, if additional filter was used.
|
||
|
||
|
||
17.01 beta 2017-08-28
|
||
-------------------------
|
||
- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
|
||
7-Zip now uses additional memory buffers for multi-block LZMA2 compression.
|
||
CPU utilization was slightly improved.
|
||
- 7-zip now creates multi-block xz archives by default. Block size can be
|
||
specified with -ms[Size]{m|g} switch.
|
||
- xz decoder now can unpack random block from multi-block xz archives.
|
||
- 7-Zip command line: @listfile now doesn't work after -- switch.
|
||
Use -i@listfile before -- switch instead.
|
||
- The BUGs were fixed:
|
||
7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.
|
||
|
||
|
||
17.00 beta 2017-04-29
|
||
-------------------------
|
||
- NewHandler.h / NewHandler.cpp:
|
||
now it redefines operator new() only for old MSVC compilers (_MSC_VER < 1900).
|
||
- C/7zTypes.h : the names of variables in interface structures were changed (vt).
|
||
- Some bugs were fixed. 7-Zip could crash in some cases.
|
||
- Some internal changes in code.
|
||
|
||
|
||
16.04 2016-10-04
|
||
-------------------------
|
||
- The bug was fixed in DllSecur.c.
|
||
|
||
|
||

|
||
-------------------------
|
||
- 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
|
||
-------------------------
|
||
- 7zr.exe now support AES encryption.

- New small SFX module for installers (SfxSetup).
|
||
|
||
|
||

|
||
-------------------------

||
- The BUG in LZMA SDK 9.* was fixed: LZMA2 codec didn't work,
|
||
if more than 10 threads were used (or more than 20 threads in some modes).
|
||
|
||
|
||
