1HISTORY of the 7-Zip source code 2-------------------------------- 3 424.09 2024-11-29 5------------------------- 6- The default dictionary size values for LZMA/LZMA2 compression methods were increased: 7 dictionary size compression level 8 v24.08 v24.09 v24.09 9 32-bit 64-bit 10 8 MB 16 MB 16 MB -mx4 11 16 MB 32 MB 32 MB -mx5 : Normal 12 32 MB 64 MB 64 MB -mx6 13 32 MB 64 MB 128 MB -mx7 : Maximum 14 64 MB 64 MB 256 MB -mx8 15 64 MB 64 MB 256 MB -mx9 : Ultra 16 The default dictionary size values for 32-bit versions of LZMA/LZMA2 don't exceed 64 MB. 17- 7-Zip now can calculate the following hash checksums: SHA-512, SHA-384, SHA3-256 and MD5. 18- APM and HFS support was improved. 19- If an archive update operation uses a temporary archive folder and 20 the archive is moved to the destination folder, 7-Zip shows the progress of moving 21 the archive file, as this operation can take a long time if the archive is large. 22- The bug was fixed: 7-Zip File Manager didn't propagate Zone.Identifier stream 23 for extacted files from nested archives (if there is open archive inside another open archive). 24- Some bugs were fixed. 25 26 2724.08 2024-08-11 28------------------------- 29- The bug in 7-Zip 24.00-24.07 was fixed: 30 For creating a zip archive: 7-Zip could write extra zero bytes after the end of the archive, 31 if a file included to archive cannot be compressed to a size smaller than original. 32 The created zip archive is correct except for the useless zero bytes after the end of the archive. 33 When unpacking such a zip archive, 7-Zip displays a warning: 34 "WARNING: There are data after the end of archive". 35- Some bugs were fixed. 36 37 3824.07 2024-06-19 39------------------------- 40- Changes in files: 41 Asm/x86/Sha256Opt.asm 42 Asm/x86/Sha1Opt.asm 43 Now it uses "READONLY" flag for constant array segment. 44 It fixes an issue where ".rodata" section in 7-Zip for x86/x64 Linux had a "WRITE" attribute. 45- The bug was fixed: 7-Zip could crash for some incorrect ZSTD archives. 46 47 4824.06 2024-05-26 49------------------------- 50- The bug was fixed: 7-Zip could not unpack some ZSTD archives. 51 52 5324.05 2024-05-14 54------------------------- 55- New switch -myv={MMNN} to set decoder compatibility version for 7z archive creating. 56 {MMNN} is 4-digit number that represents the version of 7-Zip without a dot. 57 If -myv={MMNN} switch is specified, 7-Zip will only use compression methods that can 58 be decoded by the specified version {MMNN} of 7-Zip and newer versions. 59 If -myv={MMNN} switch is not specified, -myv=2300 is used, and 7-Zip will only 60 use compression methods that can be decoded by 7-Zip 23.00 and newer versions. 61- New switch -myfa={FilterID} to allow 7-Zip to use the specified filter method for 7z archive creating. 62- New switch -myfd={FilterID} to disallow 7-Zip to use the specified filter method for 7z archive creating. 63 64 6524.03 2024-03-23 66------------------------- 67- 7-Zip now can use new RISCV filter for compression to 7z and xz archives. 68 RISCV filter can increase compression ratio for data containing executable 69 files compiled for RISC-V architecture. 70- The speed for LZMA and LZMA2 decompression in ARM64 version for Windows 71 was increased by 20%-60%. 72 It uses arm64 assembler code, and clang-cl is required for arm64 assembler code compiling. 73- Some bugs were fixed. 74 75 7624.01 2024-01-31 77------------------------- 78- 7-Zip uses file C/Precomp.h that is included to all c and c++ files. 79 CPP/Common/Common.h also includes C/Precomp.h. 80 C/Precomp.h defines the following macros (if _WIN32 is defined): 81 Z7_LARGE_PAGES 1 82 Z7_LONG_PATH 1 83 Z7_WIN32_WINNT_MIN 0x0500 (or higher) 84 _WIN32_WINNT 0x0500 (or higher) 85 WINVER _WIN32_WINNT 86 UNICODE 1 87 _UNICODE 1 88 if _WIN32_WINNT is defined already, C/Precomp.h doesn't redefine it. 89 90- 7-Zip now can unpack ZSTD archives (.zst extension). 91- 7-Zip now can unpack ZIP and SquashFS archives that use ZSTD compression method. 92- 7-Zip now supports fast hash algorithm XXH64 that is used in ZSTD. 93- Speed optimizations for archive unpacking: rar, zip, gz, wim, cab. 94- Speed optimizations for hash caclulation: CRC-32, CRC-64, Blake2sp. 95- The bug was fixed: 7-Zip for Linux could fail for multivolume creation in some cases. 96- Some bugs were fixed. 97 98 9923.01 2023-06-20 100------------------------- 101- All external macros for compiling C/C++ code of 7-Zip now have Z7_ prefix. 102- 7-Zip COM interfaces now use new macros that allow to declare and implement COM interface. 103- The code has been modified to compile with the maximum diagnostic warning level: 104 -Wall in MSVC and -Weverything in CLANG. 105 And some warning types are disabled in 2 files: 106 - C/Compiler.h for C/C++ code warnings. 107 - CPP/Common/Common.h for C++ code warnings. 108- Linux/macOS versions of 7-Zip: IUnknown interface in new code doesn't use 109 virtual destructor that was used in previous 7-Zip and p7zip: 110 // virtual ~IUnknown() {} 111 So 7-Zip's dynamically linked shared libraries (codecs) are not compatible 112 between new 7-Zip for Linux/macOS and old 7-Zip (and p7zip). 113- Some optimizations in filters code: BCJ, BCJ2, Swap* and opthers. 114- If 7-Zip uses BCJ2 filter for big datasets compressing, it can use additional temp 115 files in system's TEMP folder. 7-Zip uses temp file for additional compressed 116 data stream, if size of such compressed stream is larger than predefined limit: 117 16 MiB in 32-bit version, 4 GiB in 64-bit version. 118- Some bugs were fixed. 119 120 12122.00 2022-06-16 122------------------------- 123- 7-Zip interfaces now support high precision (1 ns) timestamps with reserved 124 fields of tagPROPVARIANT (VT_FILETIME). 125 126 12721.07 2021-12-26 128------------------------- 129- The sorting order of files in archives was slightly changed to be more consistent 130 for cases where the name of some directory is the same as the prefix part of the name 131 of another directory or file. 132- TAR archives created by 7-Zip now are more consistent with archives created by GNU TAR program. 133 134 13521.06 2021-11-24 136------------------------- 137- Bug in LZMA encoder in file LzmaEnc.c was fixed: 138 LzmaEnc_MemEncode(), LzmaEncode() and LzmaCompress() could work incorrectly, 139 if size value for output buffer is smaller than size required for all compressed data. 140 LzmaEnc_Encode() could work incorrectly, 141 if callback ISeqOutStream::Write() doesn't write all compressed data. 142 NCompress::NLzma::CEncoder::Code() could work incorrectly, 143 if callback ISequentialOutStream::Write() returns error code. 144- Bug in versions 21.00-21.05 was fixed: 145 7-Zip didn't set attributes of directories during archive extracting. 146 147 14821.04 beta 2021-11-02 149------------------------- 150- 7-Zip now reduces the number of working CPU threads for compression, 151 if RAM size is not enough for compression with big LZMA2 dictionary. 152- 7-Zip now can create and check "file.sha256" and "file.sha1" text files 153 that contain the list of file names and SHA-1 / SHA-256 checksums in format 154 compatible with sha1sum/sha256sum programs. 155 156 15721.03 beta 2021-07-20 158------------------------- 159- The maximum dictionary size for LZMA/LZMA2 compressing was increased to 4 GB (3840 MiB). 160- Minor speed optimizations in LZMA/LZMA2 compressing. 161 162 16321.02 alpha 2021-05-06 164------------------------- 165- 7-Zip now writes additional field for filename in UTF-8 encoding to zip archives. 166 It allows to extract correct file name from zip archives on different systems. 167- The command line version of 7-Zip for macOS was released. 168- The speed for LZMA and LZMA2 decompression in arm64 versions for macOS and Linux 169 was increased by 20%-60%. 170- Some changes and improvements in ZIP, TAR and NSIS code. 171 172 17321.01 alpha 2021-03-09 174------------------------- 175- The command line version of 7-Zip for Linux was released. 176- The improvements for speed of ARM64 version using hardware CPU instructions 177 for AES, CRC-32, SHA-1 and SHA-256. 178- The bug in versions 18.02 -
