The March 9 patch said 1.58 is a rebase of the game.
Can someone tell me what that means?
All the changes merged into the EXE file directly, instead of tons of modification files ducttaped on to the EXE.
Means smaller file size, and faster load times, with a few less technical issues.
In-game patches are random stuff you throw into your garage, and eventually clunk a large portion of it. So you take a day every few months just to tidy everything up, clean the mess, throw away trash or redundant stuff, and now you can enter your garage again without tripping over random stuff.
The rebase do the same thing, but to your game files. Basically, every patch just “adds up” to the base game, but it forces the game to check a lot of stuff to load before the game starts. A rebase just merge it all in the original .exe file and the game don’t need to turn half dozen boxes to find out how to load that skin added in the last event.
In general, it’s a good thing. Except that you basically have top redownload the whole game again when this happens, which is why they don’t do it frequently.
Quoted for emphasis. Probably wouldn’t’ve used a garage metaphor; but something more like different colored jean patches.
But the above is the best response.
