-In 20.xx, ar71xx will finally be dropped. As already relevant in 19.07, ath79 introduces vendor_model-variant scheme for image names. It also drops the board_names used in ar71xx, so the compatible (from DTS) will be used as board name instead (being equivalent to vendor,model-variant, and unique for a specific device).+In 21.02, ar71xx will finally be dropped.

 While creating the new and shiny target, we again took the opportunity to use more systematic names on devices, using less abbreviations and staying closer to the device name. This will it result in several changed names compared to ar71xx additional to just adding the vendor to the name. While creating the new and shiny target, we again took the opportunity to use more systematic names on devices, using less abbreviations and staying closer to the device name.

 +===== Support of Ed25519 SSH keys =====
 +
 +With the commit [[commit>d0f295837a03f7f52000ae6d395827bdde7996a4]] it is now possible to use Ed25519 SSH keys on regular (aka not tiny) devices. These keys are much shorter than RSA keys while being equally secure. For embedded devices this should speed up the login process as the keys are much faster processed.
