• Version: 17.1.0

• electron-updater version: v1.14.1

• Target: macos

In a test project, I set autoUpdater.allowPrerelease = true and published it as v1.16.9-pre on GitHub as Pre-release. Then published v1.17.0-pre as Pre-release. v1.16.9-pre successfully autoupdated to v1.17.0-pre. Then I published v1.16.10 (no pre here) as Release (not pre-release) and my v1.17.0-pre got updated to it, which was unexpected.

The chain of updates:

v1.16.9-pre → v1.17.0-pre → v1.16.10

I think somewhere the version check is missing or misbehaving.
