Does 15.10 beta upgrade automatically to introduce a recent fix?

Hello,
During beta2 I flagged up a bug that UK and US international keyboard variants were not functioning properly.
https://bugs.launchpad.net/ubuntu-mate/+bug/1506609
Martin fixed this with impressive reactivity (thanks!!) and left the comment “Fixed in the current Ubuntu MATE 15.10 daily.”

A week or two later, I’m still waiting for this fix to appear on my system but it still hasn’t arrived. A couple of other posts confirm this should happen with a simple apt-get dist-upgrade - which I’m doing several times a day.

So will it arrive? Or do I need to make changes on my system e.g. delete a config file somewhere so that the fix replaces it?

Thanks for your replies. I’m eagerly awaiting the ability to type French accents on my UK keyboard!
Merci,
D.
