For Lodestone's developers, not for use. A build of 5376705, to test and debug work in progress. It may not work.
Only Lodestone Launcher with Settings › General › Updates › Developer builds on updates to it. That setting only shows in a developer build, or once it's on. To start, install LodestoneLauncherSetup.exe (Windows), LodestoneLauncher.dmg (macOS) or a -standalone file from here, then turn it on: it then updates to the newest developer build, beta or release, whichever is newer. Turn it off to wait for a release newer than your build.
Only the newest 5 developer builds are kept; older ones are deleted.
Built from 5376705.
