How does one get updates for BB customizations?

I customise my own Debian Stretch image based off a console image dated 04 Apr 2018. I just stumbled upon bb-customisations in this repo:

Question: Do I get these customisations if I just simply do a sudo apt upgrade? If no, how do I get the latest snapshot of these customisations? Is there any downside to using an old console image? Thanks!


With regards to the customisations, they are in deb package bb-customisations. So apt upgrade does the job

$ sudo dpkg -S /etc/udev/rules.d/60-omap-tty.rules
bb-customizations: /etc/udev/rules.d/60-omap-tty.rules
