This is on my MT1300. The main issue that I have with this release is that you cannot setup a flash card as a overlay. Well you can, just don’t reboot — meaning you have to do everything manually post boot. /etc/config/fstab correctly shows my card mounting to /overlay but on reboot, /dev/mtdblock6 gets mounted to /overlay regardless of anything I try to do. I cannot for the life of me override this like I was able to with release 2. GL.iNet folks - please provide some suggestions.
Try the Post #9 procedure in this thread:
I do not work for and I am not directly associated with GL.iNet
That seemed to make things worse… (accounted for different device with the script).
For whatever reason /dev/mtdblock6 is now mounting to /rom/overlay and /dev/mmcblock0 isn’t automounting anywhere…
I’ll try downgrading to release 2 later unless there are other ideas on how to resolve this issue.

Looks like 4.3.6 release 3 “stable” branch has been pulled from the site for the MT1300. Latest beta is back to release 2 and the stable back is showing as 3.216. So back to release 2 it is for me. Next time I’ll wait a couple weeks before upgrading and having to go through this mess of an upgrade. Hopefully, downgrading resolves the aforementioned issues. I’ll report back.
It was removed not because of bugs, but because of the upgrade.
Reverting to release 2 fixed my issue. I don’t know the difference between release 2 and release 3 but there is something that breaks the ability to mount a flash card as overlay. Please double check on this prior to any further releases.

You can see from the block info that mtdblock6 goes from trying to mount on /overlay/rom in release 3 to just being a type="jffs2" in release 2
