There are two versions of Weka: Weka 3.8 is the latest stable versionand Weka 3.9 is the development version. New releases of these two versionsare normally made once or twice a year. For the bleeding edge, it isalso possible to download nightly snapshots of these two versions.
The stable version receives only bug fixes and feature upgrades thatdo not break compatibility with its earlier releases, while thedevelopment version may receive new features that break compatibilitywith its earlier releases.
Mojave uses the APFS file system, which isn't supported by older versions of Mac OS X. We recently replaced the Mac OS X/macOS installer.dmg for WEKA 3.8.3 with one that uses the HFS+ file system instead, so that people with older versions of Mac OS X can install WEKA using the.dmg.
Weka 3.8 and 3.9 feature a package management system that makes iteasy for the Weka community to add new functionality to Weka. Thepackage management system requires an internet connection in order todownload and install packages.
Every night, a snapshot of the Subversion repository with the Wekasource code is taken, compiled, and put together in ZIP files. Thishappens for both the development branch of the software and the stablebranch. Those who want the latest bug fixes before the next officialrelease is made can download thesesnapshots.
Weka 3.8 is the latest stable version of Weka. This branch of Wekaonly receives bug fixes and upgrades that do not break compatibilitywith earlier 3.8 releases, although major new features may becomeavailable in packages. There are different options for downloadingand installing it on your system:

Hi Everyone,
I am really stuck and i have been trying to resolve this for hours! I am a a beginner so i have no idea what i am really doing! I did have WEKA 3.6 on my Mac i now what to download 3.7.13. I removed WEKA 3.6 from my mac and put it into the trash. I downloaded WEKA 3.7 oracle and apple version as to be honest i have no idea what the difference is and neither of them worked anyway! I download them and i move the files (both the folder and the icon) into my launchpad. I then eject the download. When i click on the icon to open WEKA it doesn't open. I have no idea what i have done wrong as i have downloaded WEKA 3.6 oracle version and that worked! The only thing that is different now is that i recently downloaded RWEKA onto my computer to run WEKA with R. Can someone explain to me firstly what the difference between the two downloading versions are and then in layman terms how i can download WEKA 3.7.13 so that it works! My mac has OS x yosemite v 10.10.5 and the java is up to date and is Java 8 update 73. Thanks for any help, Danielle Comments are closed.
