OpenPLi does not release “stable” versions, in general we consider the nightly builds stable enough to be used on a daily basis. If for some reason there’s an issue with a specific receiver, this receiver will appear in the “Notice” section in the sidebar of this page, together with a link to a forum post explaining the issue. This link will also appear at the top of this page, as a reminder you are about to download an image that is considered unstable.
You can find the latest firmware images for your receiver in the appropriate section below. Instructions for flashing firmware can be found in the installation section of the documentation.
