I am using the email composer plugin and it requires this version of Android to update to 6.2 to get the fix, otherwise the plugin can't be updated.
I am using <plugin name="de.appplant.cordova.plugin.email-composer" spec="https://github.com/katzer/cordova-plugin-email-composer.git#0.8.3" />
However there appears to be a bug in this version and to get the update it requires android version 6.2
Here you can see current supported CLI versions
Latest CLI is 6.5.0, which brings cordova-android 6.1.2. It was released 2 months ago, while the Cordova one was released 5 months ago. So it took 3 months.
Cordova CLI 7 was released a month ago, so you'll probably have to wait for around 2-3 months until you get the Phonegap CLI updated with that version, or even more as it was a major version update.
In the FAQ | PhoneGap Docs it says that the version is updated every 6 months approximately.
In the meantime, you can try to install a previous version of the plugin that doesn't require cordova-android 6.2.0.
If that doesn't work, you'll have to use another plugin (there are a few mail composer ones) or build locally.
