Handling folds in Spyder

Spyder 4.0.1 is released, which supports code folding. If you are using anaconda, use

conda update --all

to get it.

(Spyder maintainer here) You can install the first beta of Spyder 4 to get code folding.

If you use Anaconda, you need to use the following commands:

conda update anaconda

conda update spyder

or if you use pip, then you need to run

pip install -U --pre spyder

This beta is quite stable and it has been tested for more than a year.
