Just because updating software takes time, and deepin stuff is limited in manpower.
If you do need a fast update, come join them, or make donation. Otherwise, do no expect them as what the GIANT (Google, M$, Apple) do.

I understand that. I just wonder exactly what they (or other distros for that matter) do that takes time. Is it that they test the software, like firefox so it doesn't brake Deepin or do they adapt the software somehow to Deepin.
I am mostly curious, not meant to be criticism per se, if anyone perceived it like that. Personally I just dont use the store to install software that I want the latest version of. Besides, Deepin has this wonderful "Deepin package manager" that installs .deb files with the latest version ridiculously easy. For example Vivaldi and Firefox, and once you've done that they update themselves and you don't have to be dependent of the Deepin store for that.

You can Manually Update Browser and Other App too.

Additional info:

I tested firefox 62 via debian unstable repository and it has problem.

From 15.8 planning

Preview Repository        Users can directly experience the latest deepin features, and the updates from the Debian upstream repository.

Personally I don't feel software repositories are updated too slowly (and they shouldn't be updated too frequently, in means of a reliable distro). The latest versions usually have more bugs than the stable versions, so they break things easily. That's why I switch from Arch (and Manjaro) to deepin (and Mageia).
