A pretty nice addition to [the third developer preview of the OS formerly known as Android M] is granular control over the permissions [which] each and every app requires upon installing it, giving Android users "meaningful choice of control". Just like in iOS, apps in Android 6.0 Marshmallow will only [allow] you to grant them a certain permission immediately before the app needs it and not in bulk during the installation, [as was the case] in previous Android installments.
[...] Android 6.0 Marshmallow officially introduces API Level 23, which is one of the requirements to have app permissions that can be granted on demand. All Android apps need to be updated [by their developers] so that they support the brand new API0 Level 23 libraries in order to introduce the individual granular app permissions.
SiliconANGLE notes that 6.0 is also getting native fingerprint support, a new power-saving mode, and Android Pay.
They also note
Hardly anyone with an existing Android phone will ever get to use [6.0].
[...] Android-powered devices rely on the manufacturer to update the operating system and the reality is that it rarely happens.
To put it more crudely, the Android update process is f**ked.
[...] [As Android remains open source and free to use,] Google can't force manufacturers to come to the party in terms of upgrades [any] more than it can force manufacturers to stop skinning their Android installs with their own custom user interfaces and software.
Release of Android 6.0 is expected in 2015Q4.

If it has used the old android permissions as a base, yes it would have been granular.
But instead it uses the grouped permissions that was introduced to the play store a year ago or so.
This means that you can't approve reading, but not writing something, as both are in the same category etc.
Also, there is a bunch of permissions that are accepted by default. This because Google deem them "safe".
Oh, and older apps still follow the old system of all or nothing.
