What's the difference between these 32-bit installers?

xampp-linux-5.5.19-0-installer.run
xampp-linux-1.8.3-5-installer.run

I see the file sizes are different, but did not find any explanation as to the difference in content.
Not sure which to install.

The version numbers are explained: viewtopic.php?f=13&t=69838
