|
---|
8 |
|
---|
9 | 9.17 2010-10-04
|
---|
10 | -------------------------
|
---|
11 | - IStream.h::IOutStream::
|
---|
12 | STDMETHOD(SetSize)(Int64 newSize) PURE;

16 |
|
---|
17 | 9.09 2009-12-12

19 | - The bug was fixed:
|
---|
20 | Utf16_To_Utf8 funstions in UTFConvert.cpp and 7zMain.c
|
---|
21 | incorrectly converted surrogate characters (the code >= 0x10000) to UTF-8.
|
---|
22 |
|
---|
23 |
|
---|
24 | 9.05 2009-07-05
|
---|
25 | -------------------------

28 |
|
---|
29 | 9.04 2009-05-30

33 |
|
---|
34 | 9.02 2009-04-23
|
---|
35 | -------------------------
|
---|
36 | - Bug was fixed: if swap2 filter was requests at compression,
|
---|
37 | 7-zip used swap4 filter instead (but id was swap2), so archives were incorrect.
|
---|
38 |
|
---|
39 | 4.61 2008-11-23
|
---|
40 | -------------------------
|
---|
41 | - Bug in ver. 4.58+ was fixed:
|
---|
42 | 7-Zip didn't use any -m* switch after -mtc, -mcl or -mcu for .zip archives.
|
---|
43 | - Bug in .CAB code was fixed. 7-Zip didn't show some empty files,
|
---|
44 | if .CAB archive contains more than one empty file.
|
---|
45 |
|
---|
46 |
|
---|
47 | 4.59 2008-07-27
|
---|
48 | -------------------------
|
---|
49 | - Bug was fixed:

|
---|
51 | allocated range in some rare cases.
|
---|
52 |
|
---|
53 |
|
---|
54 | 4.59 alpha 2008-05-30
|
---|
55 | -------------------------
|
---|
56 | - BUGS was fixed:
|
---|
57 | 7zOut.cpp: 7-Zip incorrectly wrote size of property records in some cases.
|
---|
58 | 7zIn.cpp: 7-Zip incorrectly work with archive, containg archive properties.
|
---|
59 |
|
---|
60 | 4.58 alpha 9 2008-04-29
|
---|
61 | -------------------------
|
---|
62 | - BUG was fixed: 7-Zip showed incorrect timestamps in ISO files.
|
---|
63 |
|
---|
64 |
|
---|
65 | 4.58 alpha 8 2008-04-15
|
---|
66 | -------------------------
|
---|
67 | - BUG in 4.58 alpha 5/6/7 was fixed:
|
---|
68 | LZMA encoder worked incorrectly, if lp != 0.
|
---|
69 | - Unicode (UTF-8) support for filenames in .ZIP archives. Now there are 3 modes:
|
---|
70 | 1) Default mode: 7-Zip uses UTF-8, if the local code page doesn't contain required symbols.
|
---|
71 | 2) -mcu switch: 7-Zip uses UTF-8, if there are non-ASCII symbols.
|
---|
72 | 3) -mcl switch: 7-Zip uses local code page.
|
---|
73 | - Now it's possible to use -mSW- and -mSW+ switches instead of -mSW=off and -mSW=on
|
---|
74 |
|
---|
75 |
|
---|
76 | 4.58 alpha 7 2008-04-08
|
---|
77 | -------------------------
|
---|
78 | - BUG was fixed: BZip2Encoder and BZip2Decoder used CEvent objects without
|
---|
79 | creating, when BZip2 code was called with one thread (with -mmt1 switch or with
|
---|
80 | default switches on single thread CPU).
|
---|
81 | - .lzma support.
|
---|
82 | - RPM and NSIS support was improved.
|
---|
83 | - LZMA now stores only (2 << n) or (3 << n) dictionary size value to LZMA properties.
|
---|
84 |
|
---|
85 |
|
---|
86 | 4.58 alpha 6 2008-03-27
|
---|
87 | -------------------------
|
---|
88 | - NTFS time extra in ZIP.
|
---|
89 | - New item property - kpidTimeType - VT_UI4 (0 - NTFS, 1 - Unix, 2 - DOS).
|
---|
90 | - Static CRC table is not required now for Lzma Encoder (in Lz MatchFinder).
|
---|
91 |
|
---|
92 |
|
---|
93 | 4.58 alpha 5 2008-03-19
|
---|
94 | -------------------------
|
---|
95 | - Creation time (-mtc switch) for .7z archives
|
---|
96 | - LZMA encoder was converted to ANSI-C
|
---|
97 |
|
---|
98 |
|
---|
99 | 4.58 alpha 3 2008-02-25
|
---|
100 | -------------------------
|
---|
101 | - Speed optimizations for LZMA decoding. Now it uses C code instead of C++.
|
---|
102 | - 7-Zip now has 128 MB dictionary limit for 32-bit version:
|
---|
103 | It's for speed optimization: kNumLogBits = 9 + sizeof(size_t) / 2;
|
---|
104 | - TAR: 'D' link flag support.
|
---|
105 | - 7-Zip now can unpack multivolume RAR archives created with
|
---|
106 | "old style volume names" scheme (-vn switch) and names *.001, *.002, ...
|
---|
107 | - Fixed bugs:
|
---|
108 | - 7-Zip FM could not copy / move files to root network folders like \\COMPNAME\FOLDERNAME\
|
---|
109 | In case of move it removed original files.
|
---|
110 | - SFX-WIN: if there are errors, it still could return 0.
|
---|
111 | - ZIP (.XPS file) isZip64 && thisDiskNumber16 == 0xFFFF.
|
---|
112 | - ZIP name updating:
|
---|
113 | If zip file contains extra field and you try to change properties of files,
|
---|
114 | 7-zip tries to delete all extra fileds (except for WzAES).
|
---|
115 | And that code could hang.
|
---|
116 | - 7-Zip GUI didn't suggest BZip2 dictionary size used in previous run.
|
---|
117 | - If creation time stamp was included in .RAR archive, 7-zip used creation time stamp
|
---|
118 | as modification time stamp.
|
---|
119 |
|
---|
120 | 4.58 alpha 2 2007-12-31

---|
180 | fixed version:
|
---|
181 | data = _matchFinder.GetPointerToCurrentPos(_matchFinderObj) - 1;
