LineageOS now has a changelog available for BlueJay: https://download.lineageos.org/bluejay/changes/And although no downloads are listed at https://download.lineageos.org/bluejay you can download an official build here:https://mirrorbits.lineageos.org/full/bluejay/20230103/lineage-20.0-20230103-nightly-bluejay-signed.zipI have not tested the build as I am satisfied with GrapheneOS and don't want to go on an adventure.
