Updating Arduino IDE


I’ve done several projects with Arduino 1.0.1 and some external libraries.
Now I want to update to 1.0.4 but do not want to break the old setup since I do not know if they will work afterwards.

What to do?
Do I need to install the new IDE in a new directory?
Will it use the old libraries or do they need to be installed again in the new environment (1.0.4) ?


PS I’m using Windows7

If you have the libraries in the default sketch folder then the new IDE should be able to use them. Just install the IDE 1.0.4 in a new directory. You can even keep the old version around just in case.
