Dates show when CustomDroid first indexed each ROM for this device, not when support originally launched.
ROM availability and links come from each project. CustomDroid indexes builds, it doesn't mirror them — always download from the official project, verify the file's hash/signature, confirm it matches your exact codename, and back up before flashing.
