For the former, it's a bit tough to track as forthcoming update schedules can be sporadic in nature and would therefore be challenging to track in real time. Not saying it is an impossibility, but a challenging forecast to reliably predict each time with certainty.
The latter, as in the latest Dev log, uses can just search the thread and input "Dev Log" as the keyword and they can then view for themselves when the latest Dev log was dropped. Not sure if it would be worth updating the OP of the thread with those details, but good suggestion either way
