Important information regarding EAP releases
SNAPSHOT or RC (release candidate) releases may be made available as part of an Early Access Program (EAP) to gather feedback or deliver fixes prior to a production release.
EAP releases normally pass all regression tests, but new capabilities may not be complete or stable. EAP releases may not be tested against all supported host releases.
Use with caution or when specifically directed by support.
To install a plugin snapshot:
Go to UPM Manage Apps.
Click Upload app.
Copy the URL link to the snapshot from this page and paste it into the From this URL field in the Upload app dialog.
If this fails to work, upgrade UPM to 2.18.3 or higher, or, download to your local computer, and then upload the file to install.
