Google has released the September security patches for the Nexus lineup. This includes the Android Nougat (7.0.0) files for the Nexus 5X (NRD90S), Nexus 9 WiFi (NRD90R), Pixel C (NRD90R), and the Nexus Player (NRD90R). If you’re still on Android Marshmallow (6.0.1), the files for the Nexus 6P (MTC20L), Nexus 5X (MTC20K), Nexus 6 (MMB30W, MOB31E), Nexus 5 (MOB31E), and Nexus 9 LTE (MOB31E) are available as well.
No one has an answer yet as to where the Android 7.0.0 update is for the Nexus 6P is. If I find out, I’ll be sure to update his post.
