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