We've recently covered some odd releases for CyanogenMod on Android, where the custom ROM was resurrecting some forgotten devices from the dead with updates that their original manufacturers wouldn't dare release for them. This isn't the case with these additions / upgrades to the CM lineup.
First, the T-Mobile LG G4 (h811) started getting its first CM13 nightlies a couple of days ago. Given that Marshmallow is just now heading to the Tmo G4 officially, Cyanogen is keeping up with LG on this one — albeit with a probably less stable release.
Second, the T-Mobile LG V10 (h901) got its first nightly yesterday, but this time it's for CyanogenMod 12.1 which is based on Android 5.1. It's the same version that's currently running on the V10, which still hasn't seen an official update to Marshmallow.
The links to both devices' CM pages can be found at the source below. And don't forget to grab the GApps package corresponding to your device and Android version so you can have access to all of Google's stuff on your newly flashed ROM.
