When Liberation was released on the PlayStation Vita, I heartily enjoyed the opportunity to play Assassin's Creed on the go. Aveline was a great addition to the franchise, and it showed that Ubisoft could actually handle a heroine with grace.
It wasn't a flawless experience however, as it had a number of frame-rate issues among a few other technical hiccups, mostly due to the fact that it was crammed onto a portable. Here we are over a year later with the HD port, and although some of the problems confusingly remain, the overall package is a much stronger effort.
In other words, you could say the original has become...liberated.
