Ruger gave their 22/45 Lite a fashion makeover for 2013. The previous version had a gold anodized upper, some strange diagonal grooves in the barrel, and black polymer grips. The new version is anodized black with traditional straight flutes, and nicer grips.
Personally, I like the new look a lot better. The only downside is that the gold version had a flat area machined on the lower section of the barrel, which would probably be helpful for adding a bottom rail for lights & lasers.
Coming up, more updates from Ruger.
