The latest build on https://download.lineageos.org/gemini is lineage-16.0-20200419-nightly-gemini-signed.zip.
In the blog it is said that 16.0 will be moved to weekly builds. But there has been no other builds Looking at the changelog there's been a few commits, mainly security fixes.
Any idea if there will be new builds for our device? Or is it on hold for the 17.1 release?
If you look closely you can see that there haven't been any updates for all the other phones as well. This is due to an error in the build server. I don't know the specifics, but you can look at the status of the servers right here: https://status.lineageos.org/
