As of 0.3.1, I will be dropping NeoForge support for older versions, and only update for the latest version, since NeoForge download counts are always relatively lower than Fabric, especially on older versions. So basically every version I update to WILL have a NeoForge version, only odler versions (1.20.1, 1.21.1, 1.21.4 etc.), when I update them, will not have NeoForge versions.
