PeaZip project development change log




PeaZip 7.3.2 introduces support for more file types, and adds the ability to auto-configure Rar.exe (if available on the system, separately installing WinRAR due RarLab's licensing terms) for creation of RAR files through PeaZip's GUI choosing "Custom" format.
7.3 line open by default archives containing non-blocking errors, and adds BLAKE2S and BLAKE2B hash functions.
Archive date/time can be optionally set equal to most recent file in archive, confirmation for deletion can be optionally skipped, new 7z fast and 7z fastest presets were added, and both Brotli and Zstandard can now be set to enhance compression using more memory (see fast compression benchmark page).
PeaZip for Windows is now supported from winget package manager, and is available as MSIX app package.
PeaZip for Linux is now available as DEB and RPM for generic x86-64 systems.

A total of 210 file extensions can now be managed by PeaZip.

Translations are available in over than 30 languages, any help is welcome to translate PeaZip to new languages and to maintain current localizations up to date, so please consider taking the time to give a look to translations directory for newer language files and for any resource useful for translators.

PeaZip 7.x change log (current version)

2019 12 01 .. CURRENT
2020 06 23
7.3.2
CODE
Various fixes

FILE MANAGER
Added support to more file extensions:
.cramfs compressed ROM/RAM file system images
.ext, .ext2, .ext3, and .ext4 filesystem images
.hfsx filesystem images
.qcow, and .qcow2c QEMU disk images
.scap, and .uefif firmware files
.mub, .pkg, and .ppmd compressed files
Archive browser now will automatically ask for password to open files with unreadable TOC, for all formats supporting TOC encryption, e.g. archives encrypted with "Encrypt also file names" option
Fixed browsing of encrypted ARC files
Fixed: can now delete files within WIM archives

EXTRACTION and ARCHIVING
[Prototype] Support for RAR compression if WinRar 64 or 32 bit is installed in the system (Windows)
Setting Custom compression type optionally aut-configures PeaZip to use RarLab's Rar.exe as compressor; if libre_directive option is set to 2 (most restrictive, not allowing closed archive formats), rar creation will be not allowed in any case
Rar.exe will be set to use PeaZip's work dir as other backend binaries
For RAR archives it is possible to set
compression level, from store to maximum
action: new archive, add, update, freshen, sync with disk
spanning in multiple volumes
password, optionally with two factor authentication (password + keyfile)
create RAR5 or legacy RAR4 archive
(RAR5) set dictionary size 1..1024 MB
(RAR5) use BLAKE2 hash instead of CRC checksum
Create self extracting RAR
Solid archive
Recovery records
Save files open for writing
Save NT security information
Save NTFS streams
Set archive time to last modified object
Improved support for more RAR options is planned in future, to allow efficient RAR creation from PeaZip GUI, providing RarLab's WinRar is installed in the system and Rar.exe is available.

please note PeaZip does not implement any autonomus RAR creation feature, which is prohibited by RarLab's licensing for RAR, and only passes parameters to Rar.exe if separately installed by the user from RarLab's packages

Delete is triggered after extraction only in case of complete extraction (extract all)
Added option to set archive time from most recent file in archive, for all 7z/p7zip formats
Added option to improve Brotli compression using more memory at cost of small impact on speed (archives created with this option may not be compatible with some Brotli decompressors)
Added option to improve Zstandard compression using more memory at cost of small impact on speed
Added new advanced options to custom compression settings files, keeping compatibility with setting files created with older versions
Presets were rebuilt accordingly new format
Two new presets: Medium compression with 7z fast, and Fast compression with 7Z fastest
It is now possible to cancel all tasks of a sequence in the case one of the archiving / extraction task fails

WINDOWS & LINUX INSTALLERS

2020 04 27
7.2.1
BACKEND
PEA 0.70
(Linux) UPX 3.96
Please note: updating UPX in Windows packages triggered false positives from multiple antimalware, consequently the update was removed from Windows packages restoring UPX 3.95.
This is not, in any way, a fault of UPX, which is and remains a legitimate and safe software, but being one of the tools that may be employed by malware to compress binary payload, it is regarded as higly suspicious by most anytivirus, and in the past it triggered several false positives for PeaZip for Windows, almost at each update, taking months to be corrected from antivirus teams - and some of false positives are not yet fixed after years, nor the feedback mails were ever answered.
For the future I'll consider about introducing UPX support as a separate plugin, so it can be stripped from main package, and manually updated by end user, to keep it up to date e.g. in the case security issues surfaces on older UPX versions.
If you want to use last version of UPX on PeaZip for Windows, please replace the executable manually, until same syntax is honored the executable can be freely replaced.

CODE
Built with Lazarus 2.0.8
(Windows) Updated custom SendTo menu links for working with 32 and 64 bit systems, packed in SendTo.7z in program's path

EXTRACTION and ARCHIVING
Fixed: advanced compression settings was not preserved after direct creation of archive form context menu
Fixed; various issues with new advanced compression settings mechanism
(Windows) Fixed drag and drop extraction of items with names containing characters non valid for filenames
Context menu Add to 7Z and Add to ZIP now uses compression settings from PeaZip configuration rather than default compression settings, unless a specific level of compression is stated (i.e. Add to 7Z ultra)

WINDOWS & LINUX INSTALLERS
(Windows) Added context menu entries to encrypt to 7Z format (checked by default), and to add to 7Z format with fastest compression (unchecked by default)

Presets for archive creation / conversion are now rewritten to use new compression setting mechanism, new presets supersedes both old presets and favourite formats menu entries
Presets are saved in PeaZip\res\presets folder, in PeaZip's program path; apart for being saved separately they are standard compression setting files and can be used as such
To customize an existing preset with a custom compression settings file, copy the desired custom compression settings file in presets folder, in place of one of the existing preset files
Optionally, editing the compression setting file is possible to change its displayed file name, the name that will be shown by PeaZip in presets menu
New presets: ZPAQ ultra, ZPAQ, ARC, Brotli, Zstandard
