The first phase focuses on limiting API access to known users — iwd, cryptsetup (for TrueCrypt/VeraCrypt), and libkcapi — while identifying unknown users to avoid breaking existing software abruptly. The change proposal still needs FESCo approval but is expected to pass given upstream direction. The post also notes that iwd is currently unmaintained upstream, with users advised to migrate to wpa_supplicant. ## Full article daily.dev links to this article rather than hosting it.
