Part of my work includes making modifications to a software application.
After making the requested modifications, I typically send an email to those in charge of user acceptance testing, informing them that they should log in to the UAT system to check the work.
In these emails I often write something like this:
The requested modifications have been completed.
But sometimes I may instead write the sentence like this:
The requested modifications are completed.
Are these both correct English? If not, please explain why.

As a simple statement of fact this is fine.
