I'm attempting to document a change that will make two things more congruent. I'd like to use a word in this way:
This change [makes similar] the two items.
The best I've been able to find by searching is "assimilate"; however, I feel that this word has unpleasant connotations in some cases and could be misconstrued. Is there a better word?
For a little more context on this specific situation: I'm making the interfaces of two different software libraries more similar. They're remaining separate libraries, but they do nearly the same thing and are now more similar in their behavior.
