DYRL stands for Do You Remember Love... which was the movie version of the Macross movie.
The movie actually fits within the continuity of Macross as it is supposed to be a movie *within* the macross universe, taking place well after the actual events of SDF Macross... hence the updated tech... the movie uses valks available at the time.. upgraded models.
The Macross itself was also retrofitted after the conclusion of Space War which, if you'll recall the end of the series, left the SDF-1 heavily damaged. Also, the two maritime ships that made up the SDF's "arms" were replaced with those space carriers ARMD. the bridge and main guns were also upgraded.
There's a pinned thread in the movie/tv section that should answer your continuity questions.
