I just updated to PyCharm 2016.3 and I'm having an issue that's driving me crazy (and didn't exist in 2016.2).
When I'm in the Python console, and I paste a piece of text, it's automatically adding a newline to the end:
So, for example, when I pasted '4201049297840004' into the python console, it put a new line in. Is this happening to anyone else? Is there a way to turn it off? I've tried using Command-Alt-Shift-V, and it did the same thing.
