Can explain the difference between flowable-ui and all-in-one?

I am new to flowable. I cannot understand difference between flowable-ui and all-in-one? Because flowable-ui (docker image) can create default table and work flow not only “ui”(display), all-in-one image can also do this。
So i am confused.

all-in-one is the old docker image that bundled all UI apps in one image.
This has been changed a long time ago to ‘flowable-ui’, see release notes: Flowable 6.6.0 release, section ‘apps’

thanks for your reply. Got it!

I notice that the UI app modules were removed from flowable-engine at the end of last year, presumably due to work on V7.
While I realize these apps were never official and weren’t maintained, are there plans to re-introduce them or something similar/equivalent?
