Het compressieformaat 7z wordt steeds meer gebruikt voor het comprimeren van bestanden. Het programma p7zip is speciaal geschreven voor verschillende Unix-, BSD- en Linux-platformen en biedt volledige ondersteuning voor het 7z-formaat. De ontwikkelaar heeft een nieuwe versie uitgebracht met 4.53 als het versienummer, deze loopt gelijk met het programma 7-Zip op het Windows-platform. De lijst met aanpassingen ziet er als volgt uit:
Version 4.53:Version 4.52:
- From Windows version of 7-zip 4.53:
- The bug in 7-Zip 4.48 - 4.52 beta was fixed: 7-Zip could create .ZIP archives with broken files.
- Some bugs were fixed.
Version 4.51:
- From Windows version of 7-zip 4.52:
- 7z now can unpack Compound files (msi, doc, ...).
- Some bugs were fixed (CAB decompressing)
- lzma (CPP/7zip/Compress/LZMA_Alone) is now multi-threaded.
- fixed #632912 : Extracting large directories takes quadratic time (this bug was not fully fixed ...)
- fixed : "7za x -odirectory archive.7z" now works even if "directory" is a symbolic link.
- makefile.linux_s390x added : support for Linux on IBM z/Series Mainframe with s390x CPU (thank y_stephen)
- fixed crashes on BeOs with the flag "@filename"
- cleanup in the makefile : defining LITTLE_ENDIAN or BIG_ENDIAN is not needed anymore
Version 4.49:
- From Windows version of 7-zip 4.51:
- Bug was fixed: 7-Zip 4.50 beta could not open some .7z archives.
- From Windows version of 7-zip 4.50:
- New switch for command line version: -ssc[-] enables/disables case-sensitive mode for file names.
- Speed optimizations for AES encryption.
- Some bugs were fixed.
- fix built of test_emul
- contrib/gzip-like_CLI_wrapper_for_7z/p7zip now supports commands like:
p7zip -- -name
p7zip "file name"
p7zip file1 file2 file3
p7zip -d file1.7z file2.7z file3.7zVersion 4.48:
- From Windows version of 7-zip 4.49:
- 7-Zip (7z) now can unpack WIM archives
- fixed : On Sparc Solaris, core dump during "7z a -sfx exe.x dir" with p7zip compiled with makefile.solaris_sparc_CC_32
- some code cleanup
- On HPUX, p7zip can get the number of CPU and the size of the memory.
- From Windows version of 7-zip 4.48:
- Encryption strength for .7z format was increased. Now it uses random initialization vectors.
- Some bugs were fixed.
- fixed #1729236 : Makefile infrastructure not safe for parallel compilation (if your make command understands -C and -j4, copy makefile.parallel_jobs over makefile)
- Now the executables are not built with the PIC (position-independent code) flag.
7z.so are still built with the PIC flag.
7za and 7zr are now faster than 7z with 7z.so.
7za, 7zr and 7r are now smaller.- contrib/gzip-like_CLI_wrapper_for_7z/p7zip now supports spaces in filename and use 7za instead of 7z.
- contrib/qnx630sp3 added to support QNX built (thanks to termterm)
