Mini Is there a 2.10 or newer Firmware for Mini - Mark 4 HW?

Hi all.

I am currently at FW 2.8.1 with Kobo Patcher.
I am a little confused about the Firmwares.
I don't like to loose the Patcher, so I update manually.
Is there a 2.10 FW or newer for my Kobo Mini available - including Patcher?
It should be Mark 4 Firmware, but the thread above says nothing about the mini.
