FOSS gamedev and creative worlds

So why as some of you might know I have recently switched to Linux(LOVIN IT!). I have also started playing singleplayer. I really like my map and was just wondering if I will be able to play on this map on 0.4.8 with all the newest features? This is the first time I have ever played on singleplayer so this is why I have never posted something like this before. Please help!

Cant wait for 0.4.8!!! :D

Everything in the newest version will work in an older world. The only time where you'd need a new world is if something new was added the the map generator.

Simple answer: Yes.
