No new version will be released until Cosmic is ready.
Edit: I don’t intend to badmouth S76 here. I love PopOS, it’s the distro that made me a Linux fulltimer. Cosmic looks great so far. However the last major release of PopOS was in early 2022.
Isn’t this pretty much the Ubuntu LTS schedule? Linux Mint has been tracking the LTS as well.
Pop!_OS has released 37 versions based on Ubuntu Jammy, though. Soon to be 38.
