Keep in mind that while we try to make sure each dev snapshot is stable enough for general testing, this is by definition a pre-release piece of software. Be sure to make frequent backups, or use a version control system such as Git, to preserve your projects in a case of corruption or data loss.
Dev snapshot: Godot 4.3 dev 3
I tested this, and only ran into one issue. After upgrading to Godot 4.3-dev3 (from dev2), when I tried to export a project to Android, I got an error:
editor/export/editor_export_platform.h:182 - Run: A valid Java SDK path is required in Editor Settings.
I found that this setting had no value: Editor Settings / General / Export / Android / Java SDK Path
I don't know if that's a new setting, or if it's value was cleared.
I set its value to "/usr/lib/jvm/java-17-openjdk-amd64". I figured that out by using my package manager to view the installed files for the current version of my JDK (openjdk-17-jdk and openjdk-17-jre).
Then the export worked.
