Make a new release

[johanbrandhorst]

Version 1.4.1 was released in May, and it's about time we have another release. We might want to wait for #671 since that would be nice to have in a new release as well, but we shouldn't wait too long.

I'm going to cut a new release later today, so #671 will have to wait until the next release.
