7-Zip 9.34 Final is now available

Update:  It appears that the release is still an alpha for now. What has been added recently are the source codes of the release. It is not clear yet when the final release will be available.

7-Zip has been my archiving program of choice until recently. The main issue that I had with it was that its development was slow paced and that support for new archive formats such as RAR5 was not integrated as a result.

I switched to the excellent Bandizip because of it which supports the format and is as convenient to use as 7-Zip (maybe even more so).

With that said, I paid attention to 7-Zip's development to make sure that I would not miss a new version.

Today that time has come. The new 7-Zip 9.34 final has been uploaded to the Sourceforge website.

The official website has not been updated yet with information which means that the only changelog information available are for the alpha build and not the final build.

7-zip 9.34 final

If you have followed development of the program you may know that several alpha versions have been released after the release of the last final version 7-Zip 9.20 released in 2010.

This means that users of the most recent stable version 9.20 will notice many new features while users of the most recent alpha version 9.34 not as many or none at all.

The history information on the official 7-Zip website end with version 9.33 at the time of writing. Information about version 9.34 alpha are only available on the forum right now:

  • The BUG in 9.33 was fixed: Command line version of 7-Zip could work incorrectly, if there is relative path in exclude filename optiton (-x) and absolute path as include filename.
  • The BUG in 9.26-9.33 was fixed: 7-Zip could not open some unusual 7z archives that were created by another software (not by 7-Zip).
  • The BUG in 9.31-9.33 was fixed: 7-Zip could crash with switch -tcab

As you see nothing major but still useful to users who ran into those bugs. There is still a chance that features have been added after the changelog has been posted.

Here is a list of major changes implemented in the program after version 9.20 was released:

  • UEFI Bios files can be unpacked.
  • LZMA decompression speed improved.
  • More email clients supported for the compress and send to email feature.
  • Files can now be moved into archives.
  • New switches for the command line version such as rn to rename files in archives or -sdel to delete files after adding them to an archive.
  • Speed improvements when opening large archives and large folders on hard drives.
  • Multi-volume self-extracting archives now supported in 7z format.
  • Files larger than 4GB in ISO files supported.

Closing Words

7-Zip users who are running the stable version 9.20 get an upgrade to a new stable version finally after more than four years. Users of the alpha version can also upgrade to the final version but won't notice nearly as many new features than 9.20 users.

As far as RAR5 support is concerned, it is still not integrated into the program.

    There is 9.38 version here:
    I’m not sure is it final or beta.

    Thanks for the info Martin! I prefer Winrar for basic things but 7zip is MUCH better at extracting those executables, etc.

    Waiting for the portable version.

    I just tried Bandizip for awhile and finally went back to 7-Zip.
    I tried everything I could find in the setup for Bandizip to store the unzipped files in my “F:\downloads\Download Extract” folder. No matter how I setup the program, it would only extract to “F:\downloads”. I have batch files that reference this program and to change this to just “F:\downloads” would be a lot of work.
    7-Zip ,also for me, was a lot easier to find and open a file under it’s menu.

      You could move the archives into f:\downloads before extraction. This way a new folder gets created in the path whenever you extract.

    RAR5 support, or lack of it, however – truly a big deal? Does anyone use it widely enough for it to actually matter?

    Also, I suspect I’ll be 35 before 7-zip releases a new stable/final build (I’m 31 currently).

      I have yet to see an RAR5 file anywhere. 7-zip suits my needs just fine. Until RAR5 becomes more ubiquitous, I don’t think I need to worry about RAR5 compatibility.

      1. Chains The Bounty Hunter said on November 27, 2014 at 7:39 am

        I haven’t either, but I considered the possibility that Martin encounters it a lot on the mass of usenet hubs he frequents or similar.

        Personally I can’t see why support of it right now, when it’s still in initial stages of potential wide use and the creation of the .rar format itself being proprietary to WinRAR (a program I imagine most would rather pirate than pay for outright – and this is not condemning either side, so please no one take offense on that) matters. It seems just as likely that if someone has put something in a RAR5 format you want, you may be able to find it in a non-RAR5 variant.

    lol, 7zip still alpha,
    what a joke?

    I prefer Bandizip. It compresses .7z much smaller and in half of the time.

    1. Lucky Limat said on November 25, 2014 at 11:46 am

      yes , Bandizip is best

  9. anohana said on November 25, 2014 at 10:44 am

    I’ve started to testing and using 7-Zip for some months, but it looks like I’ll stay with Winrar. Yes, 7-Zip is free, but slower and very rarely produces smaller files than Winrar. So that’s why I’ll drop 7-Zip (However, I’ll test this new version for some month.).

    I’ve upgraded from the link offered here, but on the About 7-Zip popup it says it’s Alpha.

    1. Martin Brinkmann said on November 25, 2014 at 9:59 am

      It is the final version though, likely something missed by the developer.

      1. Awg said on November 25, 2014 at 11:14 am

        It’s still in alpha.

      2. Redgrave said on November 25, 2014 at 10:14 am

        I guess. Thanks for the initial heads up, it was about time for a new release :)
