We have three types of firmware builds in rusEFI:

• Release builds more tested monthly-ish. Those do not change often. You can find them on the download page.
• Nightly builds are available at https://github.com/rusefi/rusefi/releases along with previous releases.
• Snapshot builds are available roughly 20 minutes after developers make changes, sometimes more broken. Anything "I've just changed XXX" is a snapshot build. The current snapshots are at https://rusefi.com/build_server/.

We avoid the term "latest" since it could mean both "latest RELEASE" and "LATEST snapshot". Please do not use the term "latest" in context of rusEFI binaries.
